There are black insects on the leaves of house flowers. Pests of indoor plants and measures to combat them. Methods for identifying and preventing thrips

Scale insects (Pseudococcidae) are the common name for homoptera insects of the suborder Coccidae, uniting representatives of the family of lamellar, giant, paired and mealybugs, as well as felt insects - they are close relatives of the scale insect. These pests affect citrus fruits, amaryllis, azaleas, asparagus, cacti, lemons, palm trees, fuchsias, grapes, camellia, cissus, gerbera, oleander, philodendron, anthurium, monstera, hibiscus, Kalanchoe, cactus. They settle on shoots, stems, leaves, ovaries and fruits of plants, significantly slowing down their growth and development. Methods for controlling mealybugs are in our publication.

What do mealybugs look like?

Mealybugs, or, as they are popularly called, hairy lice, - sucking insects, clearly visible to the naked eye. They got their name from the white cotton wool-like waxy secretions. Larvae and adult females suck young shoots, leaves, and buds. They greatly retard plant growth. The common citrus mealybug also attacks the root system.

Insects are very mobile and move well at almost any age, covered with a white powdery waxy coating, often with waxy plates along the edge. Dimensions 3-6 (0.5-12) mm, depending on the type.

Sexual dimorphism is pronounced (when individuals of the same species have two forms that differ in physiological characteristics). Males have wings (usually the first pair), normally developed limbs, and an abdomen with two tail filaments. There is no mouthparts (males do not feed as adults).

In a number of species, legs are reduced or absent. The oral apparatus is sucking. Most insects lay eggs; in some species, females are viviparous. The eggs are laid in a white cotton wool-like facial sac. Fecundity is very high; many forms give 2, sometimes up to 4 generations per year.

Larvae of the 1st instar (vagrants) actively move along the food plant and can be carried by the wind. Having attached themselves to the plant, the larvae lose mobility; After molting, the larvae of the next instar again look for places to feed. Adult females of some species can actively crawl along the food plant. Before oviposition, many forms leave the feeding area and go into shelter.

There are over 1,600 species of scale insects in the world fauna; they are distributed everywhere, but mainly in the tropics. Among the scale insects there are many pests of fruit, industrial, ornamental crops and greenhouse plants. The most famous are the greenhouse lamellar bug, the Australian grooved bug (a pest of citrus fruits, a quarantine object), the bamboo bug, the citrus bug, the seaside bug, the grape bug, the Comstock bug (a mulberry pest), and the olive pollinia.

Some species of scale insects secrete useful substances used in the paint and varnish industry (varnish scale bug and cochineal, which produces red paint - carmine).

Mealybugs are easily recognized by their white cotton wool-like waxy coating; as a rule, they are clearly visible to the naked eye. Sugary discharge (honeydew) and a sooty fungus settling on it are the following symptoms of damage.

Prevention

Conducting regular inspections for pest damage, primarily in the off-season and on plants that are especially susceptible to insect damage, such as croton, ficus, cacti, succulents, and some types of orchids. This pest is afraid of moisture and prefers dry conditions.

Fighting methods

Mild defeat is not difficult to cope with. Using a soft brush or cotton swab dipped in soapy water, clean the plant from bugs and the white cotton-like secretions they form, and then spray three times with an interval of 7-10 days with a solution of green soap (10-15 g per 1 liter of water), tobacco infusion , infusion of garlic or decoction of cyclamen. Alcohol treatment or treatment with a pharmacy tincture of calendula gives a good effect.

In case of severe damage, in addition to manual destruction, spray at intervals of 7-14 days with one of the following preparations: Aktara, Biotlin, Calypso, Confidant, Confidor, Mospilan, Tanrek, Fitoverm. You may have to try several different medications and choose the one that works best.

Folk remedies

  1. Horsetail tincture. It is very good to water and spray sick plants with horsetail tincture. Horsetail is sold in pharmacies and is used as a diuretic, blood purifier, etc. The German name is Schachtelhalmtee.
  2. Oil spray for spraying. 1 liter of water is mixed with 2 tablespoons of olive oil, and then the emulsion is applied to the plant (best by spraying).
  3. Alcohol solution with soap. Treatment of the plant with a mixture consisting of 15 grams of liquid soap, 10 ml of denatured alcohol (Brenspiritus) and 1 liter of warm water can also be successful.
  4. Garlic tincture. Take 4-5 cloves of garlic per 0.5 liters of water. The water must be brought to a boil, and the garlic must be finely chopped or squeezed. Then the garlic must be poured with boiling water and left for at least four hours. The infusion is filtered and applied undiluted with a brush to the leaves.

Chemicals

The best time to use chemicals is when the newly hatched eggs leave the womb or egg sac. They are not yet covered with protective wax and are very vulnerable.

The difficulty of fighting mealybugs lies precisely in the fact that different generations of insects are on the plant at the same time, so a one-time application of an insecticide kills only young individuals, and after some time new ones hatch. In this regard, the use of drugs should be repeated several times every 7-14 days. The higher the stage of development of the larvae, the more difficult it is to fight them.

Currently, stores sell a huge number of chemicals, including in the form of sprays and sprays. After applying them to the plant, the protective chemical begins to be absorbed and enters the plant juices. Insects suck out this juice and are poisoned.

Preparations that, in addition to biologically active substances, also contain oil, have proven themselves to be very effective in the fight against mealybugs. However, there are a number of disadvantages here. These products should only be applied to affected areas and to areas that are considered potential insect hideouts.

When using sprays, before use, you must carefully read what the minimum distance to the plant should be when applying, since the spray can greatly damage the leaves.

You can also find protective granules and so-called root sticks on sale. Here it must be borne in mind that, in addition to protective substances, these products also contain fertilizer, so before use it is necessary to carefully study their composition, since the roots of many types of plants are very sensitive to various types of salts and can burn very quickly. For such species these drugs are not acceptable. Sometimes diluting the drug in water can help in order to deliver fertilizer and medicine to the roots in a lighter form.

When controlling mealybugs, it is necessary to repeat chemical exposure procedures to prevent the emergence of a new, more resistant generation, so you should carefully monitor the re-exposure period indicated on the package.

Types of Mealybugs

Bristle Mealybug

Bristle Mealybug (Pseudococcus longispinus) - females and larvae harm plants. The body of an adult female is 3.5 mm long, oval in shape, orange or pinkish in color, covered with a white coating. The mealybug has well-developed legs, thanks to which they can easily move from plant to plant. Females are viviparous. They usually accumulate in the form of colonies on the underside of leaves, on branches, in leaf axils and on young shoot tips.

The bristlebug is a fairly large insect, easily noticeable on the plant due to the white powdery coating that covers its body and the white waxy formations in the form of cotton balls. Damaged leaves turn yellow and fall off. Shoots are stunted in growth. Scale insects crawl under the bark of citrus fruits and under the scales of bulbs of bulbous plants. Plants damaged by scale insects are severely depressed, stunted in growth, leaves turn yellow and fall off. Sooty fungi can settle on the secretions of scale insects.

Grape mealybug

Grape mealybug (Pseudococcus citri) - the body of the female is broadly oval in shape, pink or yellowish in color, covered with a white powdery coating. Legs are well developed. Males are very rare. The hatched larvae settle throughout the plant, on shoots, on leaves along the main veins. When severely damaged, scale insects form huge colonies that suck out all the juices from the plant. The leaves turn yellow, the shoots dry out. Sooty fungi settle on the secretions of scale insects.

Primorye mealybug

Primorye mealybug (Pseudococcus affinis) - is one of the most common types of scale insects. The body of an adult female is elongated-oval, 3-4 mm long, 2-2.5 mm wide, grayish-pink in color, covered with a white powdery coating. Legs are well developed.

Males are much smaller, winged, and fly all summer. Females lay eggs in egg sacs, which are a white, fluffy, shapeless mass of waxy cobweb secretions. Typically, oviparous females hide in secluded places: cracks in the bark, in twisted leaves, in the forks of branches. The larvae are small, mobile, yellow, completely devoid of waxy coating.

They quickly spread throughout the plant and are spread by wind, humans and animals to other plants. The larvae turn into an adult insect in 1-1.5 months. By sucking out all the juices from the plant, they cause stunting and then death of the plant. Damaged plants grow poorly and do not bloom. Sooty fungi settle on the secretions of scale insects. The leaves turn yellow and fall off.

We hope that our tips for dealing with scale insects will help you! We are waiting for your comments!

Root pests of cultivated plants are the most insidious insects. Gardeners and vegetable gardeners cannot always notice or anticipate their appearance in a timely manner, and only by stunted growth can root damage be diagnosed.

By sucking the juice and boring through the rhizomes, insects deprive the plants of the opportunity to receive nutrients from the soil. Gradually, foliage and young shoots die off, plants wither and die.

Getting rid of multiplying pests is quite difficult. The easiest way to protect beds and flower beds is preventative treatment of the roots before planting.

Click beetle larvae

Centipedes

Centipedes are natural orderlies of the garden and vegetable garden. However, their accumulation becomes a big problem.

The main diet of insects is the remains of rotting vegetation. But when there is a lack of food, they begin to become interested in various cultural plantings. For example, strawberries.

The safest way for humans to fight is to set up traps. Near the beds, holes are dug into which wire cages with carrots or potatoes are placed.

Large colonies of insects can be destroyed by treating the soil with a solution of Aktellika, Fitoverma or Aktary.

In strawberry and strawberry beds, treatment is carried out before the berries ripen.

Earthworms

Earthworms are the main soil formers that contribute to soil aeration and moisture.

They feed on plant remains, but pose some danger to immature garden and flower crops. Actively moving in the ground, worms can damage thin roots and cause plants to dry out. Indoor flowers can suffer the most from worms.

It is almost impossible to fight these insects in open ground. But it’s quite easy to protect indoor flowers from their effects. To do this, place the pot in a bowl of water for eight minutes. The worms begin to choke and crawl out on their own.

Many lovers of ornamental plants may notice small black dots on the underside of the leaf. And only a few know that these are thrips on indoor plants - small pests that become especially aggressive in spring and summer, causing great harm to the crop. Pests suck sap from flowers and leaves and also transmit viral diseases. As a result of their influence, flowers fall off, leaves dry out, and secretions of their vital activity appear, on which sooty fungus can settle.

  2. Signs of thrips damage to flowers
  3. Methods for identifying and preventing thrips
  4. Methods for controlling thrips

Most often it goes to dracaenas, varieties of palms, ficus, citrus, roses, monstera and laurel. Lesions in the form of black dots are not the only manifestation of the disease; viral infections that spread to nearby healthy flowers are also observed.

Flower thrips are dipterous insects whose length ranges from 0.5 to 5 mm. Young pests are colored green, yellow and pale yellow; adult individuals are found in black, sandy and brown shades. In this way, the insects manage to camouflage themselves, making them difficult to detect. The larvae are too small, lay eggs, and have a gray or light tint.

There are many types of this pest. Thus, one of the most dangerous for ornamental crops is the Western Californian flower thrips, which is an individual up to two millimeters long, located in buds, inflorescences, and on leaves. The pest likes to settle on indoor plants such as roses, gerberas, chrysanthemums, cyclamens, etc. Given the location of thrips on indoor plants, their treatment is difficult, since most of the population is inaccessible to chemical influence.

Signs of thrips damage to flowers

Characteristic signs of plant damage by pests are:

  • the presence of yellow spots on the surface of the sheets at the beginning of infection;
  • the appearance of silvery dotted streams at further stages of disease development (not necessary for all types of insects);
  • on the lower part of the leaf there may be an accumulation of yellow and brown spots, as well as black dots;
  • Over time, spots and lines merge;
  • holes may appear at the site of the lesions, leaves wither and fall off;
  • when the buds are infected with Western flower thrips, deformation of the inflorescences is determined. So, roses have flowers that remain closed.

Pronounced viral symptoms of crop disease are:

  • yellowish or brownish round spots on the leaves;
  • the stem is covered with a black or brown coating;
  • Damage to the leaf bases in the form of necrosis is observed.

From the beginning of the infection process to the appearance of signs of activity of the Californian color triplex, 1-2 weeks pass, during which a new generation is formed.

Methods for identifying and preventing thrips

For early identification and detection of insects, it is recommended to regularly inspect flowers and leaves of crops, especially from the underside. When visually examining, it should be taken into account that, for example, Western California flower thrips likes to be located in the most illuminated areas, gathering on flowers and the top leaves. Blue and yellow sticky traps will help you identify thrips on indoor plants.

Preventive care for pets involves cleaning them from dust, spraying them, you need to ensure that the air is not very dry, that is, maintaining sufficient humidity in the room.

Too much nitrogen fertilizer promotes the development of flower thrips. An insect can get into an apartment with bouquets brought from the street. It is quite difficult to remove pests from buds and flowers, since it is necessary to shake them off and hit them on a table with white paper placed on it, on which the insects will remain.

Methods for controlling thrips

It is quite difficult to get rid of thrips on indoor plants, so at the first signs of the disease it is necessary to isolate the crop and clean it of infected elements (leaves, flowers).

At the initial stages of infection, you can wipe the plant with a solution of laundry soap using a soft sponge. This measure will not eliminate the pest, but will only reduce its population. It is recommended to leave the flower in soap under a plastic bag for some time.

Treatment with water with a few drops of machine oil, kerosene or foliage polishing agent diluted in it is effective. However, it should be remembered that such products are harmful to the plant, so their use on crops with thin and delicate leaves is excluded. Leathery leaves can be wiped 3-4 times with alcohol.

In case of severe damage to flowers by pests, it is impossible to do without treating thrips on indoor plants with the help of chemicals. The number of such products is quite large: Fitoverm, Mospilan, Aktara (as a sprayer or added to the root), Confidor, Intavir, Dantop, Apache, etc. Specialized stores may offer products under different names. A drug such as Spintor, an insecticide of natural origin, has proven itself to be quite effective.

The most important thing when purchasing chemicals is to carefully study the instructions for use, and before processing, wash the plant with water. Chemical treatment will have to be carried out not just once, but in several stages. In the period between manipulations, flower stalks must be removed.

If, after treating the crop against Western flower thrips with an insecticide, the pest returns again, then there is no need to despair. It's worth trying another remedy. After all, the effects of drugs are different; perhaps another drug will be more reliable and effective.

If the infection is mildly affected by flower thrips, you can try traditional methods of protection. For example, mix 85 gr. garlic, passed through a garlic press, 50 ml. mineral or vegetable oil with 10 ml. laundry soap and 950 ml. water. The mixture should sit for 24 hours. Before use, you need to dilute the solution in a ratio of 1 to 19 with water, that is, 950 g. take 50 ml of water. mixtures. Spray the plant with the resulting substance.

Spider mites

The most common pest of indoor flowers. Characteristic signs of damage: if the leaf is exposed to light, pinpoint punctures, whitish or yellowish, are visible. Gradually they merge into spots. The leaves turn pale and acquire a grayish tint. Then the leaves dry out and completely lose color. This is a typical pattern, but in some cases the leaves turn red or bronze. In some plants, the leaves do not change shape even when the spots are large, in other cases they are severely deformed and curled.

The leaves turn yellow, cobwebs appear on the flowers, dots appear on the leaves as if pricked by a needle, the flowers do not grow, the tops of the shoots wither - these are signs of spider mites. Advice from experienced gardeners on how to fight ticks using folk remedies or chemicals.

Oribati mites

A package of orchids arrived, and there were black bugs, like ticks, running around quickly. Who is this?

Oribatid mites or oribatids are soil arthropods. By 2015, more than 7,000 species of oribatid mites have been described. Who are they - pests or beneficial living creatures? Do we need to destroy them, what means should we use to fight them? What to do if orchid mites have settled in orchid pots.

Thrips on indoor flowers are not uncommon; they enter our home from the street, garden flowers, purchased indoor plants, and cut flowers (from bouquets). They spread very quickly on house plants, sucking juices from them, contaminating the leaves with skins and excrement. Thrips is dangerous because it has several stages of development, some of which are secretive - females lay eggs directly in the leaf tissue, and nymphs hide in the ground. In addition, eggs and nymphs have integuments that protect them from the action of contact insecticides. Therefore, the fight against thrips takes place in several stages.

Close-up photo of thrips - pest

Silver spots, discolored areas appear on the leaves, the shoots dry out and become deformed, the plant does not bloom, the leaves turn yellow, small black drops or crumbs appear on the surface of the leaves - these are signs of thrips. Look at photos of the pest and compare it with your plant.

From the point of view of indoor floriculture, the danger of scale insects is that due to parthenogenesis - the birth of females without fertilization, scale insects can reproduce all year round, producing about 5-6 generations, the process of changing generations is continuous. At the same time, males among indoor scale insects are extremely rare, but if they appear, for some reason they are very scary. Someone begins to think that this unknown, terribly gluttonous creature. In fact, the development cycle of scale insects, with or without males, is no different. The males themselves do not harm the plants - they simply have nothing to eat. In fact, male scale insects hatch for a single mission - fertilization, therefore, all they have are eyes, wings and genitals.

Mealybug

The bristlebug or mealybug is a small insect that lives on plants. Its body is covered with a white, waxy coating, which makes clusters of pests look like cotton balls.

Scale insects cause serious damage to indoor plants, and it is quite difficult to remove them at home. What to look for: If the leaves turn yellow and fall off, the shoots are stunted, small white spots are visible on the stems or under the leaves. Scale insects climb under the bark of indoor fruit exotics, under the scales of bulbs of hippeastrums and other bulbous plants, and hide in the fluffy hairs on the stems of begonias. Sooty fungi can settle on the secretions of scale insects.

Close-up photo of mealybug - pest

You won’t always notice this pest right away: scale insects can hide for a long time in the root zone, near the surface of the ground, or in the axils of leaves.

And only when the colony of scale insects grows numerous and voracious will the pests be noticeable on the leaves. But by this time, as a rule, the plant withers, turns yellow irrevocably and dies.

Whitefly

Whitefly is a pest of indoor and garden plants; all species easily reproduce in an apartment; some species quietly winter in mid-latitudes and breed under our windows in the spring. The whitefly especially loves celandine, which grows under our windows, and in gardens it spoils any vegetables, especially cabbage, and berries.

How to identify the pest - photo of whitefly, measures to combat whitefly.

At home, aphids can cause harm all year round. They multiply quite quickly, forming colonies that cover more and more territory. But unlike mites, aphids are large pests and are easy to see with the naked eye. Aphids focus on the most tender parts of the plant - the tops of shoots, buds, flowers. For many plants, the easiest way is to prune the affected shoots and tear off the flower stalks. For plants that form a rosette, wash the leaves with a sponge and green soap, and clean the leaf axils with a cotton swab dipped in alcohol.

If aphids are very rampant on indoor flowers, spray the plants with any insecticide. The following drugs will help you: Aktara, Confidor, Tanrek, Fitoverm, Inta-Vir, Iskra, Iskra-Bao, Deciss and other drugs.

Green potassium soap is also an indispensable helper in gardens - it has no odor and is not poisonous to people. Potassium soap should be diluted at the rate of 20 g of liquid green soap per 1 liter of water. Spray secluded places especially carefully - the tops of shoots, leaf axils, apply a foam cap on the buds. Do not rinse off the soap solution!

Nematode

The nematode comes in various types; the root one usually forms spherical growths or swellings. Stem or leaf nematodes do not form swellings, but cause severe deformation of leaves, stems, and buds. Flowers, as a rule, do not even open. Begonias, gloxinias, ficuses, and ferns suffer greatly from nematodes. Their leaves wrinkle, seem to shrink, turn brown between the veins, young ones grow immediately twisted and ugly.

Some types of nematodes also form galls on flowers; nematode damage is often accompanied by symptoms of bacterial infections.

Fungus gnats

Sciarides or fungus gnats are small annoying midges that appear in flowers and fly throughout the apartment. They do not harm themselves, they do not eat the flowers, but mosquitoes are a sure sign that the plants are systematically flooded. You need to check the soil in pots with flowers, because if you do not eliminate waterlogging, the roots of the plants may rot.

If mosquitoes manage to lay eggs in the soil, they hatch into larvae that feed on rotting organic matter and can partially damage plant roots.

Mining flies

The larvae of these flies gnaw out the core of the leaves, leaving discolored patterns of passages on them - min. They damage the leaves of trees, shrubs, including conifers, and herbaceous plants; in indoor conditions they can affect violets (Saintpaulias), succulents (euphorbia, sedum), hibiscus syngonium and other plants...

Root mites

Root and onion mites feed on the underground part of plants - they gnaw out bulbs and feed on succulent roots. They are detected at a stage when the plant has already been severely damaged - growth is inhibited, the leaves turn yellow, buds and flowers do not form, sometimes one-sided drying out of the crown occurs - in individual branches, but more often the plant has general signs of starvation - chlorosis. Often, wounds on the roots and bulbs become infected, and the plant becomes infected with fusarium.

High soil moisture promotes more rapid proliferation of root mites. Very often, affected indoor plants, especially small and tender ones, die. The best prevention is soil disinfection and quarantine of all purchased plants.

Occasional pests: woodlice, weevil, enchitraea, caterpillars

There are pests that appear quite rarely in flower pots - these are enchytraea; woodlice and earthworms can be brought in with the soil for planting plants; weevils or woodlice can get into the house from garden soil. If you have something crawling in your pot, look here, you might recognize the pest...

Many of them are not as dangerous as they seem, and sometimes not dangerous at all, for example, poduras or enchitraea can eat rotting plant roots, but in themselves do not cause the death of indoor flowers. Plants die from overwatering and putrefactive infections.

Poduras, springtails, springtails

Some small white fleas are jumping in pots with indoor plants. Gray worms swim in the tray after watering. Small brown spiders crawl around the roots. All these are soil inhabitants - springtails, springtails and podura. Harmless, in essence, inhabitants of soil rich in humus and organic matter. They come to our house with soil from the garden or store-bought soil. But as long as the soil moisture is moderate, the bugs are not visible. When the soil inside the pot does not dry out for many days, the roots of the plants begin to rot, and the duras multiply in large numbers.

Podura is a sign of poor care for indoor plants, systematic waterlogging, frequent watering, or incorrectly selected soil (too moisture-intensive, heavy, non-porous).

No one can avoid the appearance of indoor pests: neither a novice gardener nor an experienced one. Some, scale insects or aphids, attack many types of indoor plants, others are more selective and prefer certain species and in certain conditions. For example, mites rarely harm the ficus benjamina, but the scale insect eats it with pleasure.

If pests are detected, you must first get rid of them mechanically by wiping the leaves and stems with a sponge soaked in a soap solution. It is imperative to remove damaged buds, flowers, leaves and shoots; if the leaves begin to turn yellow or become stained, they will not recover. If the pest is noticed on only one plant, it is better to isolate the flower pot and watch the rest.

Try not to use insecticides unless absolutely necessary, especially toxicity class 2. All pest control chemicals are unsafe for humans and animals (birds and fish). All of them release toxic substances to one degree or another. Therefore, if it is possible to fight pests with folk remedies, i.e. herbs, onion peels, as well as biological plant protection products, then you should definitely try them first.

Currently, the issue of using pesticides (plant protection products against diseases and pests) is approached quite carefully, but so far we can see warnings on the packaging of chemicals about precautions, and they cannot be completely safe.

Folk remedies for pests of indoor plants

  • Yarrow - 80 g of dry crushed leaves, pour 1 liter of boiling water and leave for 36-48 hours, spray against aphids, thrips, mites.
  • Tobacco, shag - leave 40 g in 1 liter of water for two days, strain and dilute with another 1 liter of water, spray against aphids and thrips.
  • Onions - leave 15 g of chopped onions in 1 liter of water for 5-7 hours in a tightly closed container, spray against aphids and mites.
  • Celandine during flowering - infuse 300-400 g of fresh or 100 g of dry celandine in 1 liter of water for 24-36 hours, spray against false scale insects, aphids, thrips.
  • Kerosene -2 g per 10 liters of water + 40 g of laundry soap - against thrips and mites.
  • Dandelion officinalis - 300-500 g of crushed roots or fresh leaves are infused for 2 hours in 10 liters of warm water, filtered and sprayed against thrips and mites.
  • Marigold flowers - pour a glass of dried flowers into 1 liter of warm water, leave for 2 days, filter and spray the affected plants against thrips.
  • Alder leaves - a glass of dry alder leaves is poured with one liter of boiling water and left for 24 hours. Then it is heated to 50 °C and kept in this infusion before planting the bulbs and tubers for 5 minutes. In this way, root mites are prevented.
  • Wood ash - 1 cup of ash is infused in 5 liters of water, then a quarter of a piece of grated laundry soap is added there, sprayed against ticks and thrips.

Are your flowers getting sick even though you comply with all the conditions? In this case, you should suspect a pest! In home conditions, which are often far from natural, flowers are more vulnerable. Online diagnostics will help you recognize ticks, aphids, scale insects, etc. Pests of indoor flowers: photos, signs and methods of combating them.

Spider mite

The most common and insidious pest! Spider mites thrive on indoor plants, especially in winter and early spring. Heating, dry air and high temperatures create favorable conditions for its reproduction. Considering that this flower beetle is very prolific, it can easily migrate to other “neighbors”!

The tick is an arachnid and can look different. The most common types are common spider mites, red mites and cyclamen mites.

Signs

Regardless of the type of mite, the results of its activity cause the death of the leaf! The harmful insect feeds on flower sap, sucking it from leaves and young shoots. This immediately affects the appearance of the flowers: they lose their brightness, richness, and fade. On some plants, yellow spots appear, which gradually lead to yellowing of the foliage, on others, the leaves dry out at the edges and become deformed. Often, a tick can leave behind a cobweb, which is visible in the gap between the branches and leaves. And sometimes you can see the pests themselves! Thus, the common white mite is visible to the naked eye on the inside at the base of the leaf. The cyclamen mite prefers fluffy plants, and the red mite even settles on the petals of flowering plants.

Risk group
The common mite mainly affects decorative deciduous trees: hibiscus, ficus Benjamin, fuchsia, citrus fruits, dracaenas, tradescantia, adenium, ivy. Although it is dangerous for all indoor flowers, succulents are less susceptible to its effects.

The cyclamen mite prefers plants with fluffy leaves - cyclamen, violets, gloxinia. The red mite can settle on any plant, but its favorite delicacy is flowering species - roses, balsams, callas, orchids, and citrus fruits.

Treatment and prevention

Most mites cannot tolerate high air humidity, so the best prevention is regular spraying (not only the top, but also the underside of the leaf) and a warm shower. If pests are already present on the plant, you can wash the leaves with a solution of laundry soap. In summer, if possible, take flowers out into the garden or onto the balcony! At first, spraying with a solution of green soap can help!

If the mite has managed to spread widely and damage the leaves, you will have to resort to the help of acaricides - chemical preparations to combat mites. These include “Akarin”, “Agrovertin”, “Inta-vir”, “Vertimek”. “Neoron” destroys not only mites, but also their larvae, and “Fitoverm” is the safest for plant microflora. To prevent the tick from returning, you need to correct mistakes in care!

Scale insect and false scale insect

Insects from the family of scale insects, whose body is covered with a shield. This feature not only determined the name of the pest, but also made it invulnerable to spraying with chemicals. But unlike the previous representative, the scale insect does not move; on the contrary, having attached itself to the plant, it remains motionless. So it's easy to spot!

Scale insects are sucking insects; they, like leeches, suck out the sap of the plant, while secreting a sticky liquid that clogs the pores, preventing the flower from breathing. The false scale insect is a close relative of the scale insect, surpassing it in size. By the way, this harmful family has many varieties: they are round, oval, white, brown, brown from 2 to 7 mm in size.

Signs

Affected flowers lag behind in growth and development, shed leaves and buds. Scale insects on indoor plants literally “stick around” the branches and even the main trunk, and can also hide in the axils of the leaves. Externally, these pests look like droplets of wax, or growths! Small scale insects form clusters that resemble plaque along the stems and leaf veins. As a result, leaves and even branches may die, first becoming covered with red-brown or yellow spots. Scale insects are especially dangerous for young shoots!

Risk group
Deciduous plants (especially ferns, asparagus, ivies, lemons, begonias) are most often chosen as the location of the scale insect, but it can also appear on succulents (ficus, zamioculcas), and also often affects orchids.

Treatment and prevention

Provoking factors for the proliferation of scale insects are dry air and lack of light, characteristic of the winter period. They can also enter the apartment from the street! Weakened, diseased plants, in which metabolic processes are disrupted for one reason or another, are a real bait for scale insects. Healthy flowers with strong immunity are protected from these pests!

First of all, it is necessary to remove dead parts and also remove all visible scale insects. This can be done with a warm shower, a soft sponge (or soft brush) and laundry soap. An alternative would be to soak a cotton swab soaked in lemon juice or vinegar solution. Alcohol can burn an already damaged plant, and oil will clog the pores!

At this stage, you can get rid of older individuals that are not affected by insecticidal sprays. To destroy scale insects and their larvae that are invisible to the eye, it is better to play it safe and additionally treat the plant with insecticides. For these purposes, the drugs “Aktara”, “Aktellik”, “Arrivo”, “Fitoverm” are used. The most gentle method of control is a solution of green soap, but it is effective in the initial stages!

Thrips

Another type of sucking pests, which, unlike the previous ones, for the time being hide in the thickness of the leaf. The fact is that the larval stage occurs inside the leaves, where thrips reproduce. By the time they grow up and find themselves outside, they will already have time to do quite a lot of damage to the plant! The development cycle lasts about 20 days, after which the larvae turn into insects with small elongated bodies measuring 1.5 mm, which easily fly from branch to branch and are capable of infecting all specimens in the home collection.

Thrips disrupt the structure of the leaf plate, the leaf becomes deformed, loses color, darkens or becomes discolored and gradually dies. In addition, adult insects, like scale insects, leave behind sticky secretions that clog the pores of the plant and can provoke fungal diseases.

Signs

In the initial stage, thrips are not difficult to identify by the characteristic markings on the leaves. Chaotic light dots, “strokes” and entire paths appear on the surface of the sheet, which gradually spread, and ultimately can merge into one large whitish spot! Adult insects can also be seen with the naked eye - they have a dark oblong body, are able to fly, and when they land on a flower, they leave behind a silvery trail of sticky secretions.

Risk group
The pest is omnivorous, but its favorite plants are palm trees with large leaves, citrus fruits and even succulents (ficus rubber, hoya, monstera, aspidistra, laurel, eucharis, syngonium, senoplia).

Treatment and prevention

The main thing is to notice the first signs of the appearance of thrips on indoor plants in time, so that they do not have time to develop from larvae. In this case, you can stop the process with insecticides by spraying and root treatments. After all, being inside the leaf, pests become invulnerable to external disinfection, which is why they water it at the root! But to prevent insects from appearing outside, the above-ground part is sprayed.

At the initial stages, green vegetable soap copes well with this task (it can be bought in flower and garden stores). If thrips has severely affected the plant, use the preparations “Aktara”, “Dantop”, “Apache” (for root treatment), as well as “Fitoverm”, “Intavir” (for external treatment).

The website flowery-blog.ru advises regularly inspecting the inside of the leaves, spraying the plants, and ventilating the room. Thrips can appear even in summer, but they, like other pests, choose weaker flowers as their “target”.

Mealybug

These pests are popularly called “hairy lice”; they are the closest relatives of scale insects and are also sucking insects. They were nicknamed so for their appearance - the clusters look like cotton wool. Mealybugs on indoor plants love young shoots, leaves and buds! It sucks out the juice, severely inhibits the growth of plants, causes the death of its parts, young shoots, shedding of buds, buds, drying out and deformation of shoots and leaves.

This enemy sometimes hides in the axils of the leaves, becoming invisible, but multiplies very quickly, so it spreads to the soil, shoots and even roots. More than 2,000 species of scale insects are known in nature; all of them pose a danger to plants! In indoor culture, it is the white mealybug that is most often found.

Signs

The bug is bad at hiding; it is revealed by white cotton-like secretions in which the female insects lay eggs! Usually, clusters of them can be seen in the axils of new leaves, on young shoots. In addition to the “pieces” of cotton wool, you can also notice the pests themselves - they are not large, about 3 mm in size, also white in color, with an oblong body.

Risk group
It’s impossible to say exactly which plants the scale insect loves! Its target can be both decorative foliage species, succulents and even cacti. For example, monstera, chrysolidocarpus, nolina, Kalanchoe, anthurium, camellia, azalea, clivia, amaryllis, hibiscus, asparagus.

Treatment and prevention

It’s not difficult to exterminate an unexpected guest at first! It is enough to wipe the leaves, remove the white coating and disinfect the affected areas. This can be done using a cotton swab or a soft brush. A soap solution is suitable for cleaning, and for subsequent disinfection - calendula tincture, or any herbal alcohol infusion. A good preventative measure is to spray with a solution of green soap. This will help prevent relapse!

In case of severe damage by scale insects, more radical therapy is needed - watering and spraying with insecticides - "Aktara", "Vermitek", "Intavir", "Tsvetofos", "Fitoverm". If the bug has managed to spread, it is better to completely replace the soil in the pot, after first inspecting and washing the roots with running water.

It is necessary to periodically inspect the flowers for the presence of an evil insect. Especially young leaves and shoots! The scale insect does not like humidity, so spray and wipe the plants more often.

Whitefly

A sucking insect, about 3 mm long, similar in appearance to a white moth. It reproduces quite quickly, laying eggs in groups on the inner surface of the leaf. Adult insects also stay in groups, sucking juices from leaves and young branches - the most tender parts! As a result, the leaves become discolored, turn yellow and fall off.

These houseplant pests can fly, but they usually sit lazily on the inside surfaces of leaves until disturbed. While feeding, these nasty flies leave waste products on plants, which subsequently become the basis for the development of fungus. Most often, the whitefly can be seen in the summer; it is also a garden pest and a frequent visitor to greenhouses.

Signs

Recognizing whiteflies on flowers is as easy as pie: white larvae remain on the underside of the leaf, forming groups, as well as a characteristic whitish coating. At this stage it is easiest to deal with the pest!

Risk group
Most often, plants with delicate leaf plates and thin epithelium become victims of whiteflies. These are nephrolepis, tradescantia, pereromnia, fuchsia, pelargonium, ficus Benjamin, abutilon, balsam.

Treatment and prevention

At the larval stage, the insect can be eradicated by spraying with insecticides, the most effective of which is Aktara. “Agravertin”, “Inta-vir”, “Akarin”, “Fitoverm” are also suitable. If the insects have already turned into moths, spraying alone is not enough, because the white moth is very mobile. In this case, use adhesive tapes that catch flies. They will become traps for flying whiteflies!

Like other aggressors, this one also loves dry air and warmth. Spray and wipe the leaves more often, inspect them from all sides to catch the pest in time, ventilate the room more often.

Outwardly, it is also similar to a moth, but differs in color (from light green to black), the size of adult insects is about 3 mm. Lives in large colonies, mainly on garden flowers! An indicator of the spread of aphids in garden conditions are ants, which absorb the sweet secretions of aphids. These secretions attract other insects and serve as a provoking factor for the development of fungal diseases.

Aphids on indoor plants can be found in the summer. Feeding on their juice, aphids infect young shoots, interfere with development and growth, and cause deformation of old leaves and leaf fall. A plant attacked by aphids quickly dies! Therefore, it is important to have time to get rid of the insect before it multiplies greatly. Aphids and other pests of garden flowers.

Signs

The appearance of aphids can be observed on the apical shoots, buds, and young branches that the adult pest adheres to. As a result, the leaves curl and become deformed. Aphids do not always know how to fly; there are also wingless individuals! Aphid larvae usually hide on the lower surface of the leaf.

Risk group
Like whiteflies, aphids select plants with delicate foliage. The most vulnerable are decorative deciduous species with small leaves.

Treatment and prevention

The treatment is also similar to the previous case! Timely treatment with insecticidal and antifungal drugs (Akarin, Aktara, Iskra-bio, Inta-vir, etc.) can help. It is important to quarantine the plant in time and inspect those near it, because aphids move easily!

If the insect did not manage to occupy the entire plant, you can cope without toxic drugs - give the flower a warm shower using laundry soap, or spray it with a solution of green soap.

Caring for indoor plants

To grow indoor flowers, you need to be familiar with the basic rules of caring for them. Some plants require minimal attention, others (rare or tropical specimens) are very capricious. The slightest mistake leads to their death or loss of their presentable appearance.

First of all, the gardener must know how to get rid of pests. There are quite a lot of types of them. Appear on house flowers: aphids, thrips, scale insects, false scale insects, spider mites, mealybugs, fungus gnats, root mites.

1 Harmful and persistent aphid

The simplest and most common pest is aphids. It comes with or without wings. Individuals are egg-shaped. Dangerous due to rapid reproduction. They don't have to have a female nearby. Most often, “clones” simply appear. In terms of species, pests are very diverse; they can be yellowish or even black.

Aphids are capable of sucking sap from a plant. At the same time, the pests release poison. After the toxin gets on the leaves, they become twisted and deformed. After some time they die off. The tops of the plant become twisted. The shoots stop growing.

The waste products of aphids (aphids) heavily contaminate the leaf blades of flowers. As a result, the normal functioning of crops is disrupted.

Aphids are carriers of various viruses. They are transmitted through the pest's saliva. Infection causes enormous damage to plants.

It is very easy to notice signs of damage on plants. Pests settle in large colonies, most often on the fleshy, juicy and most tender parts of the plant. They leave behind a residue. If there are a lot of aphids, then their larvae can make the plant weak and dilapidated.

If pests are detected, it is best to bathe the plant in the shower and then spray it with a special preparation designed to combat aphids. A week later, for prevention, the plant is treated again.

Types of palm-like indoor plants and their care

2 Thrips

Thrips are found almost every day. If you pick up an onion and remove the top husk, you can see the second layer. If it is sticky and unpleasant to the touch, and has a silvery tint, then the harmful effects of thrips are observed.

Noticing pests on a plant is not so easy. Its features are:

  • elongated body (dimensions can be up to five millimeters);
  • unremarkable color (can be black, gray or brown).

Thrips are omnivores. They can devour with appetite both a delicate rose and a prickly cactus. Plant tissue damaged by pests dies. In its place, black dots and large holes form. The leaves fall and wither. The plant loses its presentable appearance.

As a preventative measure you should:

  • humidify the air in the room (this type of pest does not like moisture);
  • inspect the leaves both on the underside and on the surface;
  • Give flowers showers from time to time.

After getting rid of the problem, the flowers are treated with a systemic fungicide. This type of pest is capable of transferring diseases from one plant to another.

Diseases of indoor flowers and ways to combat them

3 Scale insect, false scale insect

There are many varieties of scale insects. They feed on any crops. Once on the plant, they begin to secrete a sticky liquid on which the sooty fungus can settle.

The body of an adult insect has a hard waxy shield. This feature of the pest makes it resistant to the effects of drugs, so spraying does not always help. Young individuals do not have such protection; it is a little easier to deal with them.

Individuals (regardless of age) cause serious damage to the plant. They feed on its juice. Even poisonous crops are susceptible to their attack.

After the pest appears, the young shoots of the plant begin to dry out. After this, the flower stops sprouting new shoots. It pours and the stems turn yellow and then fall off. If you do not get rid of the scale insects at this stage, you may lose the plant.

For prevention, you should spray the plants and ventilate the room. If possible, you need to cut off the affected part of the flower. Specialized stores sell drugs designed to kill this type of insect. Inspection should be done every few days.

4 Spider mite

Spider mites appear unexpectedly. It is almost impossible to notice it until the plant itself shows that it is sick - spots appear on the leaves.

At the first sign of a pest, white dots can be seen on the back of the leaves. After this, the leaves dry out, may turn yellow, and the buds become deformed.

How active a tick will be directly depends on the temperature in the room. The higher she is, the more he likes it. If the conditions for the pest are not very suitable, then the females may begin to hide in the soil, under fallen leaves, or in potted cracks.

When caring for plants, it is better to collect fallen leaves, wipe them with a damp sponge, or bathe the flowers in warm water. The surest way to fight is to spray with a solution of effective drugs that can be found in pharmacies or in specialized stores. It is best to use several types of poisons. Such ticks adapt to them very quickly, and after a while they are not afraid of them.

5 Mealybug

Mealybug is another pest of indoor plants that belongs to the sucking insects. The length of the individual reaches three and a half millimeters. It has an oval-shaped body with growths, whitish or pinkish in color. Such a pest can settle either in the axils of the leaves or on the stem itself.

The insect has only one pair of wings. Its larvae are able to penetrate the roots of plants. Scale insects protect laid eggs with secretions that have a cotton-like structure.

Mealybugs pierce the leaves and buds of the plant, and then suck out its juice. They do this until the crop dries out. Young insects cause particular harm. This is explained by their mobility and the need for nutrients necessary for active growth. Those plants that have the misfortune of being attacked by pests shed their leaves. Their shoots begin to lag behind in development and growth.

During puberty, males' oral apparatus atrophies. They stop drinking the juices of the plant.

Scale insects secrete a liquid that promotes the development of sooty fungus. You can fight the pest manually, armed with a cotton swab. With its help, adults are removed. After this, you should carry out the procedure of spraying with preparations that will help destroy small specimens.

6 Fungus gnat (sciarids)

This pest is a black and gray insect with a narrow body and a rounded head. An adult is unable to harm the plant. The danger comes from larvae that live in moist soil. They gnaw at the tender roots of the plant. After this, the crop begins to hurt, stops blooming, and withers. The plant may even die.

If there are a lot of midges, they begin to feed on the above-ground parts of the plant. Young shoots are destroyed first.

To identify this harmful insect, you need to carefully examine the soil in which the flower grows. If no mosquito larva comes into view, then everything is fine. It will be enough to simply destroy those insects that fly. To do this, resort to sticky tape or dichlorvos. If larvae are found, then you need to treat the soil with special powders, which can be recommended to the flower owner in the store. Barguzin is perfect for wrestling.

To avoid the appearance of pests, you do not need to heavily moisten the soil. The plant should be kept in dry conditions.

7 Root mites

Root mites are small in size. They are very tenacious, so it is not so easy to remove them.

The most famous is the bulb mite. He prefers to be on the bulbs of flowers such as: gladioli, hyacinths, tulips.

The pest lays a huge number of eggs after eating away the tissue inside the bulb. Subsequently, the bulb disintegrates and becomes soft and loose.

This type of tick loves a moist environment. The best way to prevent this is to store flower bulbs and tubers in a cool, dry place. In such an environment, such ticks are much less likely to survive and reproduce.

There are mites in almost any substrate. They may even be useful. Thanks to them, the microflora living in the soil can function normally. There are even predators that are ready to eat other plant pests, but these types of mites are not dangerous for the flowers themselves.

The best way to control pests is to prevent their spread. When purchasing, you need to carefully inspect the plant. At home, wash it and place it away from others for observation. It is not recommended to bathe plants together in the same container, place them on the same tray, swap trays, or place them too closely. All this increases the likelihood of pest spread. The soil for transplanting crops must be sterilized. To increase the resistance of flowers, compliance with growing and care conditions is important.

When using chemicals, you must strictly follow the recommendations set out in the instructions, as well as take precautions when working with them. You should choose the safest drugs.

If the treatment does not help and pests appear on the plant again, do not despair. The methods of action of the drugs are different and, perhaps, another remedy will be more effective.

It is impossible to guarantee protection from all pests. But you need to approach flower growing wisely. If you treat plants with care, attention, and devote enough time to caring for them, then the house will always be green. Insects will not be able to significantly harm the flora if the owner does this.

There are quite a few pests on indoor plants. Most often they are very small and not always immediately noticeable. They live and reproduce both in the soil and on parts of the plant itself. If pests of indoor plants appear and measures are not taken against them, then the flowers begin to wither, turn yellow, and then die altogether.

What needs to be done to save pets? First of all, find out what harmful insects have infested the flowers. To do this, a thorough examination of the plant itself and the soil is carried out. After this, they begin a merciless fight using various methods. Remember, any delay is fraught with disastrous consequences.

Insects live in the soil (on roots), on leaves, stems, and gnaw buds.

Pests of indoor plants

Plants react to each pest in a special way: they can change the color of leaves and slow down their growth. When visually examining a houseplant, you can notice changes in the leaves and stems.

The appearance of white spots

White spots are a signal of the appearance of:

  • Mealybug or rootbug. You need to examine all parts of the flower. If you notice “cotton” lumps, it means there is a pest.
  • When whiteflies appear, the leaves become sticky and may fall off.
  • The presence of a red spider (clover) mite can be determined by the whitish mesh, spider mite by the cobweb. Leaves with a large number of insects die off.

What do yellow spots signal?

If yellow spots appear on the leaves, you need to inspect the leaves. If fingers stick to them, these are marks left by scale insects. The cause may be the appearance of enchytraea. Tiny white worms live in the soil right at the root.

Brown spots

The presence of brown, brownish spots on the bottom of the leaf and white streaks on top indicates the action of thrips.

Deformation of green parts of the plant

If the shoots and leaves on the flowers begin to deform, it means that the flower is affected by aphids or cyclamen mites. Aphids leave behind sticky residues. It sucks the juice from indoor plants, which can cause them to dry out. If dust appears on the leaves below, they curl—the mite is in control.

Withering

The cause of drooping leaves and shoots is fungus gnats, leaf or root-knot nematodes.

Description of pests

Pests of indoor plants can cause harm and lead to the death of green spaces if they are not dealt with. Let's look at the most common insects and their destructive activities.

Spider mite

Spider mites are the most common “guest” on indoor plants. Due to their small size, they cannot be seen with the naked eye. You need to examine the lower part of the flower, because these pests do not tolerate light and moisture. Insects may appear in a dry and hot room. In such conditions, the development of spider mites is rapid.

If you have geraniums or palm trees, then they need to be inspected constantly. Insects pierce the tender part of the leaves and suck out the juice. As a result, the leaves become faded and crumble.

Aphid

Aphids can be seen despite their small size. They come in black and green. Insect colonies multiply rapidly: the female lays at least 150 larvae, which after 7 days themselves enter the reproduction stage.
Females of the third generation have the ability to fly. They move onto any indoor plants and lay larvae. Diseases are transferred to flowers on their paws, for example, different types of flower mosaics. Getting rid of aphids is not as easy as it seems.

Shields

Scale insects on indoor plants are a dangerous pest; they love to settle on cuttings, leaves, and stems. It is not difficult to detect: it is flat, oval, with the lower part of its body tightly adjacent to the substrate.

These pests are different. Real scale insects hide under their shells, just like turtles. False scale insects do not have this possibility, since this part of the body is inseparable.

The favorite colors of these pests are:

  • lemons;
  • oranges;
  • tangerines;
  • oleanders;
  • ivies;
  • palm trees

Scale insects settle on the lower part of the leaf. Colonies develop quickly. Slowly moving dots appear on the leaves, somewhat reminiscent of plaques. The leaves around their habitat turn yellow. Insects suck out the juice of tender plants and shoots, depleting the plant. If you do not start a timely fight, indoor flowers die.

Thrips

Ficus and palm trees are affected by a small jumping beetle - thrips. The females make holes in the leaves or flower buds and lay eggs. The damage is microscopic and impossible to notice with the naked eye. A signal that thrips are on indoor plants is a silvery pattern appearing on the leaves. The insects themselves live on the back side of the leaf.

White Podura

These creatures can also jump. This is a soil insect that lives directly in pots. It is distinguished by an elongated body, on which sparse hairs are visible. There are antennae on the head. Most often they appear in soils rich in humus.

The basis of nutrition is plant residues, but it does not disdain the living root system. It is clear that the eaten roots can no longer cope with their function, the plant slows down its growth and may die.

Mealybugs

These are white worms; they love the back of the leaf in the places where the vein runs. Females are large, up to half a centimeter, very fertile. They build houses for their offspring that look like balls of cotton wool, and lay eggs in them. The hatched larvae are mobile and quickly conquer space on the flowers.
Flower growers who grow cacti need to constantly inspect the plants for signs of mealybugs. These pests of indoor plants prefer them and it is necessary to take immediate measures to combat them.

Whitefly

Whiteflies are, by and large, greenhouse insects. If you purchased flowers in these places, do not be lazy to examine them carefully. Even one female whitefly on indoor plants will produce huge offspring in a short time. Then the question will arise of how to fight. The pest's favorite flowers are fuchsias, ferns, and geraniums. The two-millimeter insect feeds on plant sap, and as a result it weakens and withers.

Fungus gnats

It often happens that flower growers notice small flies flying around their flowers, but do not attach any importance to it. And in vain, because the fly lays larvae in moist, fertile soil. The larvae are microscopic, so their appearance is not immediately noticeable. The danger of insects is that the smallest creatures feed on the root system of plants. As a result, the flower dies.

How to control pests on indoor plants

Many novice gardeners are wondering how to deal with pests of indoor plants. The answer to this is important, since insects multiply rapidly, time must not be wasted.

There are different ways to help get rid of pests:

  1. mechanical;
  2. biological;
  3. folk;
  4. chemical.

If pests of indoor plants are correctly identified, and measures to combat them will be effective.

Mechanical

You need to start with the measures that are safest for humans, especially since they often help a lot. Before starting work, you should disinfect and sharpen your tools. All damaged leaves and shoots are cut off, and the cut areas should be sprinkled with activated carbon.
Bugs and visible larvae are selected manually: scale insects, slugs, caterpillars. Leaves with pests such as aphids can be wiped with a cotton pad. A contrast shower and spraying with water helps get rid of pests living on the green parts of the plant.

Biological

How to fight harmful insects with biological means? Such preparations are created based on plants. Most often used:

  • "Fitoverm";
  • "Agrovertin";
  • "Iskra-Bio".

Before use, you should read the instructions. Since they destroy pests, they contain poison in small doses. The plants are treated early in the morning and left in a shaded place until all parts of the plant are dry. The room where the treatment was carried out is ventilated. You need to wash all exposed parts of the body with warm water and detergent.

Traditional methods

If indoor plant pests appear, treatment can be carried out with time-tested folk remedies. For this purpose, decoctions and infusions are prepared from:

  • yarrow;
  • chamomile;
  • dandelion;
  • marigolds;
  • nettle;
  • garlic;
  • Luke;
  • peels of oranges, tangerines, lemons.

These environmentally friendly and harmless plants can effectively destroy harmful insects. Steamed citrus peels can be buried in the soil. Insects don't like their smell.

An infusion of tobacco, stove ash, a solution of potassium permanganate, furatsilin or soda works well. To prevent the liquid from immediately draining from the plants, laundry soap is added to it.

Chemical

When using chemical pest control products, rapid success can be achieved. It is better to resort to their help as a last resort if other methods have not given a positive result. It should be remembered that such products are unsafe for humans and beneficial insects. You need to work with chemicals with the window open, removing children and animals from the room. In addition, when working you need to use personal protective equipment. After work, you need to thoroughly wash your hands and face.
The treated plants are placed in the shade until the solution is completely dry. The area where the treatment was carried out must be washed with hot water and detergents.
Remember that chemicals are toxic, therefore, they should be stored in places inaccessible to children and pets.
Popular and effective remedies for pests of indoor plants:

  • "Karbofos";
  • "Chlorophos";
  • "Syphos";
  • "Trichlorometaphos";
  • "Pyrethrum";
  • "Decis";
  • "Fury."

They are capable of destroying almost all harmful insects.

Getting rid of harmful insects

Shchitovka

The shell of insects makes them invulnerable even to toxic drugs. If there is a large concentration of pests, you should clean them with a toothbrush and moisten them with alcohol.
The best chemicals to use are:

  • Actellicom;
  • Detis;
  • Intavir.

Getting rid of thrips

If thrips appear on flowers, they must be urgently isolated from healthy plants and treated. Place flowers in a cool room with high humidity.

An adult insect can be destroyed with special preparations:

  • Karbofos;
  • Spark-bio;
  • Fitoverm.

Thrips eggs survive safely in the soil. Treatment alone will not be enough. Repeat in a week, just by this time a new batch of pests will hatch. It is advisable to replant the plant in a new pot and fresh soil. To avoid transferring the larvae to a new container, the roots are washed with clean water.

People have long used garlic infusion to get rid of thrips. You can take a different route: spread chopped garlic on the soil, cover the flower with cellophane and leave for 2-3 hours. Repeat the procedure every other day until complete destruction.

Plants will be healthy if timely prevention is carried out and the rules for caring for each indoor flower are followed.
Use high-quality soil; be sure to disinfect it before planting. Purchase your indoor flowers from reliable sellers. It is easier to prevent the appearance of pests than to fight them.

All living beings are susceptible to diseases and attacks from enemies, and indoor plants are no exception. Not only improper care and unfavorable conditions contribute to the withering of plantings. There are also pests of indoor plants that pose a serious threat to your “green friends.” This article will tell you about the most common types of such insects.

Many flower lovers are familiar with tiny white moths, whose body length is no more than 2 mm. A distinctive feature of the pest is a yellowish body and two pairs of pollinated wings:

Thanks to the sucking mouthparts of the plant's sap, as a result it gradually withers and may even die.

On a note!

Greenhouse dwellers prefer hibiscus, pelargonium or begonia. It is enough for just one individual to appear, so that after a while the houseplant is attacked by an entire population of whiteflies. Therefore, when detected.

Aphids

In nature, there are both wingless and winged individuals. They can enter the house through a window, along with purchased plants, or even in a bouquet of flowers brought.

Hairy aphids

Mealybugs, or hairy aphids as they are also called, are considered one of the most dangerous pests. These white worms live on the stems and the back of the leaves where the veins pass. Their presence is indicated by a cobweb-like white coating, as well as the sticky liquid they secrete.

Female pests are highly fertile. They lay eggs in secretions that resemble balls of cotton wool. After a while, mobile larvae appear from them, which very quickly spread throughout the plant. Therefore, having discovered traces of the presence of mealybugs, it is necessary to get rid of them urgently.

Root scale insects

Root bugs also pose a threat to the root system of plants. Pests live in the ground or on the lower part of the stems, which is why a whitish coating appears on them. Not very active females are much larger than males (reach up to 2.5 mm). They have a cylindrical body covered with a waxy coating. Females lay clutches of eggs in special chambers created from their own mold-like secretions.

The males bear a close resemblance to the whitefly. They stop feeding as adults, and therefore die rather quickly. That is why entire generations of insects are female.

On a note!

The presence of insects inhibits the growth of flowers, the leaves begin to fade and wrinkle. Infected plants are also susceptible to fungal diseases.

Shields

A serious danger to the plant is the false scale insect, the distinctive feature of which is the absence of a waxy shell. Female insects are larger in size (up to 5 mm); unlike males, they do not have legs and wings. The body of females is covered with a convex shield, which can be either elongated or round in shape.

Sucking pests settle on the stem or along the veins on the back of the leaf. There is also a hemispherical false shield, distinguished by its large dimensions and volume. Ferns, asparagus and myrtles especially suffer from it. Below is a photo of pests of indoor plants.

Podura white

  • have an elongated body covered with sparse hairs;
  • 3 pairs of legs;
  • long mustache;
  • prefer moist soil, compost and humus.

Soil pests feed on plant residues and will not refuse the living root system. This slows down the growth of the plant and can lead to its death.

Spider mites

Spider mites are one of the most common and dangerous pests of indoor plants, which many gardeners have had to deal with. The small, barely noticeable insect is difficult to see without a magnifying glass. Lives on the underside of leaf blades. It multiplies quickly under favorable conditions, namely when there is dry and warm air in the room.

Evidence that the plant is affected by mites is:

  • light spots formed after pricking leaf blades and sucking juices from them;
  • the presence of the finest cobwebs covering the surface of the leaves, which is why they acquire a silver-gray color and fall off over time.

Chinese roses, geraniums and palm trees are especially affected.

Thrips

Thrips are small insects, no more than 1.5 mm in length, that are black or dark brown in color. The lower part of the body is reddish-yellow. Pests of indoor plants live on the back side of leaves. They lay eggs in microscopic holes made in leaves and flower buds.

On a note!

The presence of thrips on a houseplant is signaled by a silvery pattern that insects leave on the leaves.


Fungus gnats (sciarids)

Often around indoor flowers you can see small (up to 0.5 cm) flies, which are called fungus gnats. Sexually mature ones infect flowers and carry the larvae of other pests. In addition, they lay eggs in the roots of plants, from which after a while larvae emerge - dangerous pests of indoor plants in the soil. Whitish worms damage the root system of the crop, causing its death.
