The first step is to separate your pots from a healthy, place them in different rooms. Gnats are insects of the marshy and waterlogged appear in and sour the soil, this is the ideal environment for the development and functioning of fungal gnats. Limit the plants some time watering, dry soils. The dried land will be the unusual environment of these parasites.
Remove the top layer of soil (approximately two inches) and backfill layer of ash or calcined sand, so you get a drying effect. Sand and ash does not give ground to gain in moisture, creates a draining effect, which will prevent the further development of midges.
Dissolve a few crystals of potassium permanganate in water to make a slightly pink solution. Spray the plant and top layer of soil with spray. This solution will not only help to decontaminate the soil and drive out the flies, but also serves as an excellent fertilizer for plants. A solution of potassium permanganate can be replaced with a soap solution.
The most safe, economical and highly effective way to combat flower Midge is the use of sulfur. To process a single flower pot, the infected Midge, you will need only four matches. Turn their sulfur heads down and stick in the ground, then slightly moisten the top layer of soil.
Stick in the ground a few crusts of fresh orange peel or lay on the ground sliced garlic into slices. Purchase in a flower shop special drug to combat fleas, since they are many ("Akhtar" or "Thunder-2"). These funds should be diluted in water according to instructions. Water the soil these chemicals only in the presence of larvae and midges in the pot.
If you have not helped all of the above tips, then you have to change the whole earth. Gently remove the plant from the pot and shake the ground, try not to damage the roots. Rinse the roots under running room temperature water and fill with new soil, preheated in the oven to avoid re-infestation of the flower. Pour a weak solution of potassium permanganate.
