Drain Flies

Read our tips on how to get rid of drain flies

Drain flies are a family of flies which can sometimes inhabit plumbing drains and sewage systems; where they are harmless, but are still annoying regardless. These flies like to live in aquatic to semi-terrestrial or sludge-based habitats like bathroom or kitchen sinks, where they feed on bacteria and continue to lay eggs. They are most active at night, but may also be seen during the day. Adult flies can live for around 20 days.

Drain flies are sometimes called sink flies, filter flies, sewer flies or sewer gnats; however their actual name is Psychodidae.

Our friendly team of plumbers have put together the below tips to help prevent drain flies.
