Houseplants Published: May 22, 2012 Reprinted: Last edits:

There are a lot of indoor flowers in our office, but lately, almost all of them have got black small midges. They swarm over plants, crawl on the ground in pots. At first, the employees and I were confused, not knowing how to get rid of them. Imbued with this problem, each of us told our friends about it, and as a result, we had a whole list of "folk" ways to fight flower midges. I bring this unique selection of tips to your attention.

But first, it would be nice to know where these midges come from.


Sciarids or, in a popular way, flower gnats appear as a result of excessive moisture of the plant, when the soil does not have time to dry out between waterings. This usually happens in the winter. The midges themselves are not dangerous for the plant on which they have settled (they more irritate the owners of the flower), but their larvae can damage the root system. If there are so many larvae in the pot that you can see them with the naked eye, you will have to transplant the affected plant into new soil, disinfected and treated with special means from flower midges.

IMPORTANT! Do not confuse fruit and flower moksha. How to distinguish them - look at the photo of a flower and fruit midge.

Prevention of the appearance of flower midges

Follow a few simple rules and sciarids will never appear in your plants:

  • periodically loosen the soil in the pot;
  • do not allow frequent and prolonged waterlogging of the soil;
  • do not forget to inspect the leaves of plants, and if you find sick, immediately remove them;
  • do not experiment with irrigation water. "Tea", "meat", "coffee" water is a real delicacy for a flower midge.

From personal experience: the best preparation for a flower midge - Mukhoed Helped 100%, there were no more midges.

So, midges start from excess moisture. To avoid stagnation of water in the substrate, water it when the upper part dries at least 1-1.5 centimeters. Use only soft water for irrigation. To soften the water, you can boil it, defend it, freeze it, acidify it with peat.

How to deal with flower gnats (sciaridams)

  • Here is one of the most economical ways. You will need 4 matches to process a medium sized flower pot. Stick each match with the head into the ground, lightly water the soil. Remove and inspect matches periodically - as soon as the sulfur disappears, insert new ones. On average, matches can cope with midges in four "shifts".
  • Method number 2. Water a flower affected by midges with a weak solution of potassium permanganate (do not overdo it - a strong concentrate can burn your plant!).
  • Method number 3. Use a mild soapy water solution for watering.
  • Method number 4. Recipe for German florists: chop 3 heads of garlic and pour a liter of boiling water. The mixture should stand for at least four hours, then sprinkle the strained garlic infusion on the plant itself and water the soil in the pot. This method is suitable for those who will not be confused by the smell of garlic in the apartment.
  • Method number 5. Eat the orange and tear the skin into pieces and stick them into the ground.
  • Method number 6, also with garlic: cut a few cloves lengthways and spread them all over the ground, cut down.
  • Method number 7. Amateur flower growers advise using the "Raptor" in the fight against flower midges. They say it helps.
  • Method number 8. Use a Mashenka-type insect repellent pencil. You can put shavings from a pencil directly on the ground and draw a few lines on the pot itself.
  • If you are not a fan of folk methods, use store products: "Thunder-2", "Bazudin", Mukhoed.


  1. Plant Pest Information

Sections: Pests Houseplant pests

With garden soil, a huge number of different pests can get into flower pots. But most often, three types of insects start to breed in them:

    fruit flies - fruit or fruit flies that look like small flies

Drosophila in nature are ubiquitous, feed on plant sap, decaying plant debris. Fruit flies are characterized by a short life cycle and extraordinary fertility.

Sciarids are relatively little studied and include up to 20,000 species. The most famous are mushroom, cucumber, potato, greenhouse. In this biological species, adults do not feed, and the larvae eat fungal mycelium, the roots of higher plants, and decaying plant tissues.

Whiteflies, or aleurodids, live on the underside of leaves and feed on plant sap. Some of their species are dangerous quarantine pests.

Types of midges, their description and photos

There are several types of mosquitoes that can settle in indoor flowers. To successfully fight them, you need to know which midges attacked the plant.

Puffs, or springtails, light midges (white, yellowish, brownish), small in size. They usually appear in winter or spring, when, due to the cool temperature, the rate of evaporation of moisture in pots decreases.

Sciarids, larger midges (up to 3 millimeters), with a black body. The midges themselves are safe, but their larvae gnaw at the root system. Also, their appearance can lead to the compaction of the substrate in pots, which impairs the air exchange of the root system.

How to get rid of midges

The first thing that needs to be learned when starting a fight is that the war should be on two fronts at once: against flying individuals, and against their larvae.

Mechanical methods

If such an extraordinary way of removing midges, such as buying an insectivorous nepentes, is difficult for you, use traditional methods of struggle.

Drying or replacing soil

It is assumed that the midge will leave the dry soil devoid of irrigation. But it is unlikely that plants will thank you for this method. It is enough to dry only the top centimeters of the soil between waterings. Larvae do not live deeper than four centimeters, so the affected soil is changed to sterile or dried in its upper part. Soil replacement is especially often used against sciarids, because their larvae are able to "sleep" for a long time in non-irrigated soil, waiting out a drought.


While the flyers are resting on the flower leaves, you can try to suck them in with a powerful stream of air. A tightly packed garbage bag is thrown away from your home. The vacuum cleaning method is unlikely to help one hundred percent, so repeat the procedure periodically and combine with other methods.


Slowly but surely fly insects will be caught by fly sticks with a tasty smell. In winter, these weapons are not available in stores, so you can make such traps yourself. To do this, it is enough to grease fabric ribbons with honey or thick jam.

A trap made from the bottom of a plastic bottle will also help. Place the apple core inside, and tie the top tightly with cellophane. The holes made in the film will allow midges to get inside, but the insects will not be able to get out back.

But you can lure springtails out of the soil with the help of a cut potato. White larvae will gladly stick around the wet cut of the nutritious tuber, and then they can be destroyed without problems.


The moisture-loving flowers are immersed together with the pot under water in a high basin. The larvae of harmful springtails will float to the surface, making them easy for you to catch.

Application of insecticides

Heavy artillery capable of taking down the enemy at all levels is modern chemistry. Neo-Dichlorvos, Raid, Raptor and other aerosols will get rid of flying insects. In order for the effect to be one hundred percent, it is important to repeat the treatment of the room after a week.

The larvae inhabiting the soil are eliminated by spilling the soil twice with solutions of Karbofos, Aktara, Agravertin, Inta-vira, Aktellik, Fitoverma or Kinmix. Between the procedures, they stand for a week, and after each of them, they do not water the plants with anything else for four days.

You can use the scattering of granules of Thunder-2, Bazudin, Kapkan or Pochin. When watering, they will dissolve and gradually destroy the larvae.

Folk remedies

Adding soap or celandine juice to the watering liquid is an old but sure way of eco-friendly pest control. There are many other methods.

Garlic, dill, tobacco, orange peel

Anything that smells strong will help to discourage flying individuals from the flowerpot. If you don't want to spoil the look of the soil with pieces of organic matter, it will be enough to grease the edges of the pot with anise oil. However, if there are already eggs in the soil, the technique will have no effect.

The plant can be sprayed with garlic tincture. The orange peel is dried and placed in a flower pot.

You can even get rid of midges with the help of dill. The twigs are stuck into the soil. Sprinkle tobacco on the ground in a pot.

Potassium permanganate, sulfur, ammonia

A light pink solution of potassium permanganate is a reliable way to kill the larvae.

Important! Increasing the concentration of the drug during watering can damage the flower roots.

Sulfur is extracted from old-fashioned match heads. They are stuck directly into the ground. When watering, the sulfur will gradually transfer to the ground.

Ammonium is placed in a small container near the flower. Its pairs will drive away flying individuals far.

Ash and activated carbon

Activated carbon tablets are crushed into powder, which is sprinkled with potting soil. Furnace ash is also spread over the surface. An adult midge will not make its way to the ground through a layer of a couple of centimeters to lay its eggs there. Ash, plus everything, will rid the soil of acidity and fertilize the flower.

Folk remedies for midges in indoor flowers

The flower grower must understand that if midges appear in indoor flowers, and especially flying midges, there is a high probability that the attack will soon spread throughout the entire home flower garden. And although adults do not gnaw leaves or drink plant sap, they lay eggs, from which very voracious larvae hatch. Noticing midges climbing around a green pet, it is necessary to take comprehensive measures: remove excess moisture, treat with insecticides and transplant into uninfected soil.

Let's consider in detail how to get midges out of indoor flowers:

  1. Step 1 - adjust the humidity. It makes sense to start fighting black flies only after the top layer of soil in the pot dries out at least 2 cm.
  2. Step 2 - open the hunt for adult insects. To do this, we use purchased or homemade (from yellow paper covered with a layer of honey) Velcro strips or a regular vacuum cleaner.
  3. Step 3 - we destroy the larvae in the soil. The easiest, but at the same time costly and time-consuming, way is to transplant the plant into a new pot with clean soil. But with a small scale of defeat, it makes sense to use one of the available means to fight the larvae: ammonia, match sulfur, garlic, potassium permanganate, vinegar, tobacco, etc.

Ammonia from midges on indoor flowers

An excellent option than treating indoor flowers from midges is ammonia available in any first-aid kit. Dissolve 50 grams of ammonia in 4 liters of water and get an excellent 2-in-1 product - a midge repeller in indoor flowers and nitrogen fertilizer. It can be used to process the aerial part of flowers from a spray bottle and destroy adults, as well as for root dressing and the simultaneous destruction of larvae and eggs of pests. Repeat watering spraying can be done at intervals of 7-10 days until a stable effect is achieved.

Potassium permanganate from midges in flowers

Another tool that helps not only get rid of unpleasant flying tenants, but also significantly strengthen green pets is potassium permanganate. So that the remedy does not harm the delicate root system of plants, potassium permanganate from midges in flowers is used, a solution that has a pale pink color. This concentration is sufficient to slow down putrefactive processes and leave pests without food. To achieve the effect, the plant is watered with it at least twice, each time allowing the soil in the pot to dry thoroughly.

Acetic acid from midges on home flowers

Ordinary vinegar will help to ward off midges that have bred in indoor flowers forever. We dilute 1 teaspoon of table or apple cider vinegar in 1 liter of clean, settled water and we will get an effective remedy than poisoning midges in flowers. In addition to the insecticidal, the vinegar solution has another useful effect - the leaves of plants after such treatment acquire a healthy shine and gloss. A solution of vinegar can be used for protective spraying or prophylactically wiped on the leaves of indoor flowers.

Tobacco from midges in flowers

An effective and inexpensive remedy against midges in flowers is tobacco. Its pungent smell scares away insects and prevents them from laying eggs. There are two ways to use tobacco. In the first case, the soil in the pot is carefully loosened, and then a layer of tobacco is spread on its surface. In the second, an infusion is prepared from it, pouring 40 grams of raw materials with 1 liter of boiling water and, after cooling, water the earth in the affected pots. This tool has a strong odor, so it is not suitable for all growers.

Cinnamon from midges in indoor flowers

As you know, midges in indoor flowers feed on rotting organic matter. To leave them without food, to slow down the putrefactive processes, ordinary cinnamon will help. Like tobacco, it can be used for sprinkling the surface of the soil and as a solution. If you are looking for how to water indoor flowers from midges, and at the same time significantly improve the overall atmosphere in your home, then there is nothing better than cinnamon, which has a pleasant aroma and stimulating effect.

The soil should be loosened regularly so that as much oxygen as possible penetrates the root system.

Question answer

What causes midges in indoor flowers?

A common reason is that they could appear when a plant is transplanted into purchased land, which has already been infected with eggs and larvae. In addition, midges could simply fly in the summer or autumn from the window and settle in your flowers. One way or another, the main factor in the emergence and reproduction of sciarids and fruit flies is moist, overflowing soil, which attracts midges and creates favorable conditions for the transformation of sleeping eggs into larvae. By the way, fruit flies could get into your apartment along with purchased vegetables, fruits or fly to the smell of a stale product, and only after that they choose your flower pots.

Why are midges in flowers dangerous?

Adults themselves are harmless, but their larvae, feeding on the juice of the roots, destroy the plant. Flower midges are especially dangerous for seedlings and young plants.

What to do to prevent midges in indoor flowers from starting up?

Watering the plants as 2 cm of the top layer of the earth dries up, as well as periodic loosening and timely removal of diseased leaves. Moderate watering will make the soil less attractive to oviparous adult midges and less fertile for larval development.
