Fungus gnats are not at all harmful to people or pets. However, when you begin to find them swarming plants in the house or greenhouse, it's time to get rid of the fungus gnats. First things first, make sure fungus gnats are the real culprit; they are often confused with fruit flies. Fungus gnats look like small mosquitoes just 1/16 inch to 1/8 inch long.
Although a few species are up to 1â2 inch long, fungus gnat adults commonly are about 1â16 to 1â8 inch long. Wings are light gray to clear, and the common Bradysia species have a Y-shaped wing vein. Because adult fungus gnats are attracted to light, you first might notice these pests flying near windows indoors.
