Drain Fly Facts
- Drain Flies are 1.5 to 5 mm in length.
- Drain Flies are considered to be part of the gnat family.
Also known as moth flies, drain flies are quite common, and although they’re basically harmless, they can become very irritating. Most homeowners find drain flies in a bathroom or kitchen. The term drain fly was coined because of the fact that these insects lay their eggs inside of the slime that develops in sink drains. Although many people consider boiling water and bleach to be effective remedies, it’s a better idea to attack the actual slime that develops inside of the drain.
