Fungus Gnat

Damp, organic-rich environments, such as potting soil of houseplants, greenhouses, compost piles, and areas with decaying plant matter. Adults are often seen flying or walking on surfaces near these areas.

Larvae feed on fungi, decaying organic matter, and sometimes plant roots (especially tender roots of seedlings). Adult fungus gnats do not feed significantly and primarily focus on reproduction.

Adults are weak, erratic fliers and are attracted to light and moisture. They often emerge from potted plants and are considered a nuisance indoors. Larvae live in the soil and are responsible for any plant damage. Their life cycle typically takes 3-4 weeks, depending on temperature and humidity.

Risks: Can be a nuisance indoors by flying around lights and windows. Larvae can damage plant roots, especially in seedlings and young plants, leading to wilting, stunted growth, and sometimes plant death if infestations are severe. They do not bite humans or transmit diseases. Benefits: As decomposers, larvae can help break down organic matter in natural ecosystems.
