Wirral Drain Fly Control

Drain flies are a widespread pest insect in the UK. Drain flies lay their eggs in drains, sewers and other standing water. They breed rapidly, meaning that if you see a couple of adult flies there is probably a lot more eggs. Adult flies will fly out of drains and typically die quickly, but they can become a nuisance inside houses. They don’t usually spread diseases but could contaminate food products.

Drain flies can be recognised by their small size and dark colour. They are covered in hair which gives them a fluffy appearance, and they have sizeable wings which they fold above themselves when not in use. Drain flies can be easily confused with fruit flies or other types of flies. Precise identification and location is essential to an effective treatment.

If you think you have a drain fly infestation, you can test drains by half covering them with a piece of tape. Leave this for about four days. If you find flies caught on the tape then the drain is infested. The best way to control a drain fly infestation is to eradicate their breeding areas. They like to breed on organic matter that’s caught in clogged drains, and so complete cleaning of drains is an effective way to get rid of drain flies. However, proper cleaning of pipes can be extremely messy. Specialist pest control companies will be able to identify and locate a drain fly infestation and carry out a highly effective treatment to control the pests.
