If small midges are bred on orchids, you have to choose ways to deal with them. To do this, you should know exactly what kind of insects started on the indoor flower.
How to get rid of small midges on an orchid
Description of pests
The first step in effective insect control is identifying the species. Small midges on orchids can destroy the plant.
Sciarids
Another name for the parasite is mushroom mosquitoes. They are noticed when a dark flock has appeared over the plant. Black and deep gray small midges in orchids are 4 mm long. Due to 2 transparent wings, they look like mosquitoes. The appearance of the black cyriad is observed in autumn and spring, when it is damp and cool indoors. There is no harm to the plant from adults, but the larvae infect the roots of the plant, going deeper to a depth of 1 cm into the ground. The affected shoots and roots are quickly colonized by rot. As a result, the flower dies.
Whiteflies
If midges have started up in the orchid and fly over the flower, gathered in small white flocks, these are whiteflies. In appearance, these are point white insects up to 2 mm in length. The pest lays the larvae on the back of the leaves and along the entire length of the stem, leaving yellow streaks behind. During the full development cycle, the larva affects more than 50% of young processes. The affected flowerpot deforms the shape of the stem. The leaves gradually dry out.

Fruit flies
Tiny midges in orchids with a yellow body color and red eyes are called fruit flies. They appear on the plant in any season. From eggs, adults grow in just 6 days. The size of an adult insect ranges from 5 mm. Often the appearance of these pests coincides with the process of feeding flowers and introducing food residues. Drosophila starts the process of plant decay.
Thrips
The elongated striped gnats on orchids with appressed wings are called thrips. They live both on the ground, where they hide, and on the leaves, from which they feed. After the invasion of the parasite, the plant is covered with many black dots or a silvery film. The insect is especially active at night, so it is difficult to diagnose during the day.
Due to the large number of bites, the affected plant gradually dries out. Pest larvae infect only leaves. If small midges are bred in the soil of the orchid, urgent measures are taken to get rid of them: the reproduction of pests occurs as soon as possible.
Top dressing with drugs
Before using chemicals, it is worthwhile to clearly recognize which midges are in the orchids. Correct identification of the parasite increases the chances of fighting it.
You can get rid of midges in orchids using the following control methods:
- Sciarids. Plants are processed in 3 stages. To destroy the insect on the leaves and stems, the well-known preparations "Reid", "Raptor" or "Neo Dichlorvos" are used. Under such conditions, the earth is necessarily etched with chemical preparations tapa "Bazudin" or "Thunder-2". The third stage is to disinfect the surface where the pot with the flowerpot was located. It is carried out with hydrogen peroxide or other disinfectant.
- Whiteflies. Treating leaves and stems from white pests is carried out with the preparations "Sherpa", "Aktara" or "Fury". The root part is not touched.
- Drosophila. To eliminate these pests, aerosols are used. The most popular among them is Dichlorvos. Aerosols "Hexachloran" and "Combat" show good efficiency. They are used strictly according to the instructions. After spraying, after half an hour, the room is ventilated.
- Thrips. This type of parasite is difficult to eliminate. In this case, the drugs "Actellik" and "Fitoverm" are used. The parasites are treated with chemicals every 10 days until they are completely destroyed. In parallel, the soil is washed under the shower with regularity once a month.

A solution based on it is made as follows: 1 g of potassium permanganate is added to 1 liter of boiled and cooled water. The liquid should take on a pinkish tint. Spraying and watering with this solution is carried out no more than once every 8-10 days throughout the month.
- Soap solution. For preparation, take 25 g of finely ground gray laundry soap and pour 1 liter of warm water. After the soap is completely dissolved, the leaves of the plant are washed. The procedure is carried out 2-3 times a month in case of pest infestations.
- Vegetable oil. Add 1.5 tbsp to 1 liter of water. l. vegetable oil. The solution is used only for spraying the flowerpot.
- Ash. Wood ash is spread over the top of the soil and on the roots of the flowerpot. It will rid the houseplant of parasites and reduce the acidity of the soil.

Periodically, the cartons are removed. Traps are changed frequently.
Prevention
For the prevention of parasites, they adhere to the elementary rules of care. These precautions include:
- drying the soil between waterings;
- moderate watering of the plant no more than once every 3-4 days;
- the absence of food near the flower that can undergo the decay process;
- holding the substrate in the freezer for 2-3 days before planting: this helps to get rid of eggs and larvae of parasites;
- timely removal of wilting or damaged parts of the plant;
- carrying out periodic loosening of the soil;
- wiping the flower leaves with soapy water several times a year, excluding the flowering period.
To prevent parasites, follow the rules of care
In order not to lure the midges, some actions limit:
- decorative moss is placed in a pot to an indoor plant;

The key to a healthy plant and prevention is, first of all, proper care.
Conclusion
If flying midges appear near the indoor flower, all possible measures should be taken to combat it, because parasites greatly interfere with the normal growth of the flower. Timely assistance to the plant will get rid of pests and contribute to the luxurious flowering of the orchid.
