Fungus Gnats resemble tiny Mosquitoes. These grayish-black flying insects are very tiny – only ⅛ inch in length.
Fungus Gnats do not bite or feed on humans. They live in damp soil and feed on fungi. Fungus Gnats themselves cause no problems aside from being a nuisance if they swarm, but the presence of Fungus Gnats in your home can indicate a different problem, like the overwatering of houseplants.
Fungus Gnats are common throughout the United States.
- Avoid overwatering plants.
- Keep yard free of organic debris, like piles of grass clippings or leaves; these are breeding grounds for Fungus Gnats.
- Repot indoor plants and discard old soil which contains eggs, larvae and pupae, this will reduce the population.
