Fungus Gnat Information - Fungus Gnats Pest Control

From our friends at GardensAlive.com

Fungus gnats are small, gray, midge-shaped flies approximately 1/4" long. They love moist soil, and soil rich in organic matter (peat moss, etc.). The larvae feed on young seedlings and this can kill a young plant, but rarely will harm an established plant. Adult fungus gnats can transmit plant disease, but mostly they are an unsightly nuisance.

Adult female fungus gnats deposit approximately 100 to 150 eggs on the surface of the soil close to the stem of the plant. The life cycle of the gnat continues as they hatch in 4 to 6 days into the larval stage, which feed on fungi, organic material and plant tissue for 2 weeks. The fungus gnat then pupates and emerges as an adult a few days later.
