Drain flies lay eggs in moist organic matter. They can lay 10 to 200 eggs at one time. After the eggs are laid, they hatch in approximately two days. They spend the next 9 to 15 days as larvae, feeding and growing before entering the pupal stage for 20 to 40 hours, after which they are considered adults. The life cycle can take as little as eight days to complete, but it might take up to 24 days under varied environmental and temperature conditions.

Drain flies get their name because they are often found near drains, both inside and outside homes or business properties. They are small insects, only growing to be about a quarter-inch long or a sixth of an inch long. Their bodies and wings are covered in tiny hairs, which give them a fuzzy appearance.
They have dark and winged bodies that range from gray to dark brownish-black. Because of their size and coloring, they are sometimes mistaken for gnats. Drain flies are most active at night when they are attracted to light, so you might see them near lamps or televisions. During the day, they rest on walls and ceilings. With a clear picture of how they look, it's easy to get rid of the drain flies in your home.
