Spider mites

The most common pest of indoor flowers. Typical signs of damage: point punctures, whitish or yellowish, are visible in the lumen of the leaf. They gradually merge into spots. The leaves turn pale, acquire a grayish tint. Then the leaves dry out, completely lose color. This is a typical picture, 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 strongly deformed, curled.

Thrips

Thrips on indoor flowers are not uncommon, they get into our house from the street, with garden flowers, with purchased indoor plants and with cut flowers (from bouquets). They spread very quickly on houseplants, suck out juices from them, contaminate 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 covers that protect them from the action of contact insecticides. Therefore, the fight against thrips takes place in several stages.

Shield

From the point of view of indoor floriculture, the danger of scale insects is that due to parthenogenesis - hatching of females without fertilization, scale insects can reproduce, all year round, giving out about 5-6 generations, the process of generational change goes on continuously. At the same time, males among indoor scale insects are extremely rare, but if they appear, for some reason they are very frightening. Someone begins to think that this is an unknown, terribly gluttonous creature. In fact, the developmental cycle of scale insects, with or without males, is no different. By themselves, males do not harm plants - they simply have nothing to eat. In fact, male scale insects hatch for the sole mission of 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 bloom, from which the accumulations of pests look like cotton balls.

Worms 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. Worms climb under the bark of indoor fruit exotic plants, under the scales of bulbs in hippeastrum and other bulbous plants, hide in the fluffy hairs on the stems of begonias. Sooty fungi can settle on the secretions of worms.

This pest is not always immediately noticeable: the worms can hide for a long time in the root zone, near the surface of the earth, in the leaf axils.

And only when the colony of worms grows numerous and voracious, the pests will be noticeable on the leaves. But by this time, as a rule, the plant withers, irrevocably turns yellow 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 from spring reproduce under our windows. The whitefly is especially fond of celandine, which grows under our windows, and spoils any vegetables, especially cabbage, and berries in the gardens.

aphid

Aphid

At home, aphids can be harmful all year round. They multiply rather quickly, forming colonies that cover an ever larger territory. But unlike ticks, aphids are large pests, they are easy to see with the naked eye. Aphids focus on the most delicate parts of the plant - tops of shoots, buds, flowers. For many plants, it is easiest to cut off the affected shoots and tear off the peduncles. For plants that form a rosette, wash the leaves with a sponge with green soap, and clean the leaf axils with a cotton swab dipped in alcohol.

If aphids are very much roaming on indoor flowers, spray the plants with any insecticide. You will be helped by: Aktara, Confidor, Tanrek, Fitoverm, Inta-Vir, Iskra, Iskra-Bao, Deciss and other preparations.

In gardens, green potash soap is also an irreplaceable assistant - it does not smell and is not poisonous to people. Potash 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 the shoots, the axils of the leaves, apply a foamy cap to the buds. Do not wash off the soap solution!

Nematode

The nematode is of various types, the root usually forms spherical growths or swellings. Stem or leaf nematodes do not form swellings, but cause severe deformation of leaves, stems, buds. The flowers, as a rule, do not even open. Begonia, gloxinia, ficus, ferns suffer greatly from the nematode. Their leaves wrinkle, as it were, shrink, turn brown between the veins, the young grow immediately twisted, ugly.

Some types of nematodes also form galls on flowers, often a nematode infection is accompanied by symptoms of bacterial infections.

Mushroom gnats

Sciarids or mushroom mosquitoes - small annoying midges start in flowers, fly all over the apartment. By themselves, they do not harm, flowers do not eat, but mosquitoes are a sure sign that plants are systematically flooded. You need to check the ground in pots with flowers, because if waterlogging is not eliminated, the roots of plants can rot.

If the mosquitoes have time to lay eggs in the soil, larvae hatch from them, feeding on rotting organic matter, which can partially damage the roots of plants.

Miner flies

The larvae of these flies gnaw out the core of the leaves, leaving on them discolored patterns of moves - min. The leaves of trees, shrubs, including conifers, and herbaceous plants are disfigured; in room conditions, violets (Saintpaulias), succulents (milkweed, stonecrop), hibiscus syngonium and other plants can be affected …

Root mites

Root and onion mites feed on the underground part of plants - they gnaw out bulbs, feed on juicy roots. They are found at the stage when the plant has already suffered greatly - growth is inhibited, the leaves turn yellow, buds and flowers do not form, sometimes there is a one-sided drying of the crown - with separate branches, but more often the plant has common signs of starvation - chlorosis. Often, an infection gets into the wounds on the roots and bulbs, and the plant becomes ill with fusarium.

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

Accidental pests: wood lice, weevil, enchitrea, caterpillars

There are such pests that appear quite rarely in pots with flowers - these are enchitrea, wood lice, earthworms can be brought in with soil for planting plants, weevils or wood lice can get into the house from the garden soil. If you have someone crawling in a pot, take a look here, you might recognize a pest …

Many of them are not as dangerous as they seem, and sometimes they are not at all dangerous, for example, podura or enchitrea can eat up decaying plant roots, but in themselves they are not the cause of the death of indoor flowers. Plants die from overflow and putrefactive infections.

Puffins, springtails, collembolans

In pots with indoor plants, some white little fleas are jumping. Gray worms float in the pan after watering. Small brown spiders crawl near the roots. All these are soil dwellers - collembolans, springtails and suckers. Innocuous, in essence, the inhabitants of the soil rich in humus and organic matter. They come to our house with soil from the garden or with storey soil. But as long as the soil moisture is moderate, 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, the podura reproduce in large numbers.

Puffiness is a sign of a violation of indoor plant care, systematic waterlogging, frequent watering, or improperly selected soil (too moisture-absorbing, heavy, non-porous).

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

If pests are found, you must first get rid of them mechanically, wiping the leaves and stems with a sponge dipped in soapy water. It is imperative to remove damaged buds, flowers, leaves and shoots, if the leaves begin to turn yellow or become stained, they will no longer recover. If the pest is seen only on one plant, it is better to isolate the flower pot, observe the rest.

Try not to use insecticides, especially 2 classes of toxicity, without urgent need. All pest control chemicals are unsafe for humans and animals (birds and fish). All of them, in one way or another, emit toxic substances. Therefore, if there is an opportunity to fight pests with folk remedies, i.e. herbs, onion husks, as well as biological plant protection products, you must definitely try them first.

Currently, the use of pesticides (plant protection products from diseases and pests) is approached quite carefully, but so far we can see a warning on the packaging with chemical preparations about precautions, and they cannot be completely safe.
