Many homeowners want to get rid of drain flies. The best way for homeowners to accomplish this goal is to eliminate breeding sites. It's essential to clean household drains, which includes removing organic slime that has accumulated in the drains. By pouring a pan of boiling water down household drains, homeowners can achieve short-term extermination.
However, the larvae of drain flies can be hard to drown, which is due to the fact that the larvae can trap air bubbles. It's important for homeowners to avoid pouring insecticides down household drains. The average life cycle of a drain fly is 10 to 15 days.
