Fungus Gnat Biology
These tiny pests belong to the families of flies called Fungivoridae and Sciaridae.
Adult Fungus Gnats prefer to lay their eggs in moist potting soil, which is why buildings containing potted plants or atriums. Soon after the eggs are laid, the larvae emerge to feed on fungus growing in damp potting soil. After feeding for a short period (little is actually known and been documented on their life cycle,) the larvae pupate. A few days after pupating, the adult Fungus gnats emerge to continue the cycle and increase the population.
