Where do cluster flies hibernate?

Cluster flies, also known as attic flies or attic cluster flies, hibernate in protected areas during the winter months. They seek shelter in secluded spaces such as attics, wall voids, behind cladding and other protected areas within buildings. These flies are attracted to warm and dark environments, making attics and similar spaces ideal for hibernation.

Cluster flies typically gather in large numbers, hence their name, and form clusters or aggregations during hibernation. They may enter buildings in the late summer or early autumn to find suitable overwintering sites. Once inside, they seek out areas that provide insulation and protection from the cold.

It’s important to note that cluster flies are not harmful to humans and do not reproduce indoors. However, their presence can be a nuisance, especially when they emerge from hibernation in the spring and try to exit the building. If you’re experiencing issues with cluster flies, it may be helpful to ask Pest Control Direct for advice and products to deal with the infestation.
