Cluster Fly Infestation
Fortunately, cluster flies do not cause structural damage, and they certainly don’t bite. However, no homeowner wants to deal with a cluster fly infestation. In most situations, cluster flies hibernate in parts of a home or building that cannot be reached, which makes them particularly hard to control. It’s likely that cluster flies will try to hide under insulation or inside of walls, and until they make an appearance, they’re pretty resistant to treatments.
