To get rid of fungus gnats, you’ll need to consider their life span, which includes eggs, four stages of larvae, pupa, and adult. Depending on the species, adults can lay up to 200 eggs. They lay eggs where fungus is growing, which usually corresponds with damp soils. The larvae feed for around two weeks, and they feed on organic matter and roots and can damage plants. When temperatures are low, this stage can last longer. They pupate near the soil surface for 3 to 7 days. Adults live a little over a week. Both larvae and adults can spread plant pathogens, such as black root rot, Botrytis blight, Fusarium wilt, Pythium blight, and Verticillium wilt. Here are some methods for addressing fungus gnats.
