Hayes 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 very quickly, which means if you notice a handful of adult flies there is likely considerably more eggs. Adult flies will fly out of drains and normally die quickly, but they can become a nuisance inside houses. They don’t usually carry diseases but could contaminate food.

Drain flies can be recognised by their small size and dark colour. They are covered in hair which gives them a fluffy look, and they have substantial wings which they fold above themselves when not in use. Drain flies can be easily confused with fruit flies or other species of flies. Accurate identification and location is crucial to a successful treatment.

If you suspect you have a drain fly infestation, you can test drains by half covering them with a piece of tape. Leave this for around 4 days. If you see flies caught on the tape then the drain is infested. The most effective way to control a drain fly infestation is to eradicate their breeding areas. They prefer to breed on organic matter that’s caught in clogged drains, and so complete cleaning of drains is an effective way to eliminate drain flies. However, proper cleaning of pipes can be quite unpleasant. Professional pest control companies will be able to identify and locate a drain fly infestation and execute a successful treatment to control the pests.
