Fungus Gnat

Damp environments with decaying organic matter, moist soil, and indoor potted plants.

Larvae eat fungi, algae, and organic mulch (sometimes plant roots); adults consume liquids or do not feed.

Weak flyers often found crawling on surfaces or hovering near moisture; attractted to light and high humidity.

Harmless to humans but can be a nuisance; larvae may damage young plant roots in heavy infestations.
