Fungus Gnat
( Sciara spp.) - These small flies are found around decaying vegetation. They have large wings and long antennae, but they are poor flyers and do not move far from their breeding site. \r\n

"Biography"
In the household, fungus gnats are usually found around potted plants because both the adult and the larvae require a humid environment. The larvae can complete their development by feeding on the moist and decaying matter in potting soil. The lifecycle may be completed in about 10 days, and the adults may live about 2 wks.\r\n

Treatment
Control by letting soil completely dry between watering. This will kill the larvae. \r\n
