Insect Control Services: Cluster Flies
Cluster flies are non-metallic gray in color with golden hairs on their thorax. They are approximately 8 to 10 mm long. Cluster flies closely resemble house flies but are larger and slower in their movements. Unlike the house fly, the wings of the cluster fly overlap when they are at rest.

Background: Cluster Flies
Because of their unusual developmental habits and the ability to heavily infest a property, cluster flies also are one of the trickiest pests to control. The main areas that cluster flies enter properties are often up high. These include soffits and facia, gable ends, dormers, vents and flashing.
Preferred Environments
Cluster flies are the most common fly found in properties during the cool months. Cluster flies are known to enter residential, recreational/cottage and commercial properties in “clusters” during the late summer/early fall months in search of a protected place to overwinter in secluded areas such as in wall voids, attics, closets and empty rooms usually in upper regions of the premises.


Treatments & Solutions
Once they are inside a property, cluster flies can cause allergies if in large numbers, attract secondary pests such as larder beetles, provide food for secondary pests, leave stains on walls and draperies, and cause an unpleasant odour.
