Cluster Flies are not a health risk, they are unpleasant. They leave stains on walls and curtains and may give off a sickly, sweetish odour if disturbed. The control of these insects is difficult but we have the tools to help you to create a pest-free space. Call us now.
Cluster flies are looking to hibernate in secluded areas of houses (like in wall voids, attics, closets, and empty rooms). If flies die in wall voids, for example, they may attract larder beetles, which will feed on the dead flies and then migrate to other areas of the house.
Cluster flies start looking for winter shelter when the days shorten in late summer and early fall. You might find them settled within the walls or attic to hibernate.
