Fungus Gnat

Natural Habitat

Moist, humid environments, commonly found indoors near potted plants, leaky pipes, or in bathrooms and kitchens. Outdoors, they can be found in compost piles, woodlands, or areas with decaying vegetation.

Diet & Feeding

Larvae feed on fungi, decaying organic matter, and plant roots. Adult fungus gnats do not feed.

Behavior Patterns

Fungus gnats are typically attracted to damp environments and decaying organic matter. Adults are short-lived, primarily focused on reproduction. Larvae are the damaging stage, feeding on fungi and plant roots. They are often seen flying or crawling near potted plants or other moist areas.

Risks & Benefits

Risks: Larvae can damage the roots of houseplants, especially seedlings and young plants, leading to wilting or stunted growth. They can also be a nuisance indoors. Benefits: In natural environments, they contribute to the decomposition of organic matter.
