Fungus Gnat

Damp environments rich in organic matter, such as houseplant soil, greenhouses, and moist garden beds.

Larvae feed on soil fungi, algae, and organic debris; they may also damage plant roots. Adults do not feed.

Adults are weak flyers usually found crawling or flying near the soil surface. They have a short lifespan and are attracted to light.

Generally harmless to humans but can be a nuisance. Larvae can damage roots of houseplants or seedlings, while adults can unintentionally spread plant pathogens.
