One of the more common fly issues we get calls for is cluster fly – also known as attic fly. These flies will often move into homes in large numbers at the end of summer and autumn to hibernate. Hence the name cluster fly. These are often quite difficult to treat because they will move into hard to reach places. It is vital that cluster fly issues are eradicated because they can also lead to other infestations such as carpet beetle.
Self treating cluster fly is not recommended. Simply spraying is not always effective and sometimes they co-exist with bats in roof and loft spaces. Bats are protected and so it is always better to have your property surveyed for the best course of treatment that will eradicate the flies bit not harm these creatures.
