  • Infestation Control

The larvae of the fungus gnat develop very quickly in damp soil. In case of excessive infestation they can cause damage, as they feed on the roots and parts of the plants. Older plants are disturbed in their growth, young plants can even die. Although the adults themselves do not cause any damage, they can become a nuisance in the indoor plant area. They usually first attract attention, as they fly up en masse when plants are watered.

The females of the fungus gnat, that dance slightly during the flight, lay up to 200 eggs into the damp soil and die after approximately 3-7 days. After approximately one week, the larvae hatch, start feeding and pupate after 14 days in the soil. Only a few days later the new generation of gnats start flying.

The annoying adult fungus gnats can be captured with yellow boards, for example. The larvae of the fungus gnats can be fought with an insecticide in a watering process.
