Fungus Gnat

Damp environments, particularly overwatered indoor plant soil, compost, and decaying organic matter.

Adults primarily feed on liquids like flower nectar or water. Larvae feed on fungi, organic debris, and plant roots in damp soil.

Weak fliers often seen crawling on soil or flying erratically near light sources. They have a short life cycle of about 3-4 weeks from egg to adult.

Generally harmless to humans. While a nuisance indoors, larvae can damage young plant roots in heavy infestations. They assist in decomposition but can spread plant pathogens.
