FUNGUS GNATS (Sciaridae)

Description:
Fungus Gnats are gray to dark gray flying insects. They are very small flies (less than 1/8 of an inch long) with two pair of wings. Often they are only glimpsed as they fly past your computer screen or around you head. This can become very annoying.

Biology:
The potting soil of indoor plants is usually the source of any fungus gnat infestation. Fungus gnats breed in, over-watered and decaying organic matter. This is often the case with indoor potted plants. Fungus gnats are a common problem in office buildings and other areas where decorative indoor plants are present. Left uncontrolled, they can breed in to the thousands. They seek light so will fly toward a computer screens or will be found in large numbers at the windows and on the sills.
