Fungus Gnat

Damp, organic-rich environments such as potting soil, compost, decaying leaves, and other moist areas with fungi growth. Often found indoors near houseplants.

Adult fungus gnats typically do not feed or feed on liquids, nectar, or honeydew. Larvae feed primarily on fungi, decaying organic matter, and plant roots, especially tender root hairs of seedlings.

Adults are weak fliers and are often seen near the soil surface of potted plants or flying in erratic patterns. They lay eggs in moist soil. Larvae develop in the soil, feeding on fungi and roots. The life cycle from egg to adult can be as short as 3-4 weeks. They are attracted to light.

Potential risks: Larvae can damage the roots of houseplants and seedlings, leading to stunted growth or wilting, especially in large infestations. They can be a nuisance indoors. Potential benefits: In natural ecosystems, they play a role in decomposition by consuming fungi and decaying organic matter.
