Have you noticed large, slow-moving flies gathering around your windows, loft space, or upstairs rooms? If so, you may be dealing with cluster flies — a common seasonal pest that often catches homeowners by surprise.

While they may appear harmless at first, cluster flies can quickly become a frustrating and persistent problem if left untreated.


What Are Cluster Flies?

Cluster flies are slightly larger than common house flies and are known for moving slowly and gathering in groups — particularly around windows and light sources. Unlike other flies, they don’t breed indoors, but they do seek shelter inside properties during cooler months.

Lofts, roof spaces, wall cavities, and upper rooms provide the perfect warm environment for them to hibernate.

Once inside, numbers can build rapidly, leading to large infestations that are difficult to manage without professional treatment.


Why Do Cluster Flies Enter Homes?

Cluster flies typically enter properties in late summer and autumn, searching for sheltered spaces to overwinter. They squeeze through small gaps around:

  • Roof tiles and eaves

  • Loft vents and fascia boards

  • Window frames and cracks in brickwork

  • Gaps around soffits and rooflines

When temperatures rise, they become active again — often appearing suddenly around windows and ceilings.
