Do you have flies driving you crazy? It is not the normal house fly, but the cluster fly. If you notice, cluster flies are much more lethargic than house flies and fly around without a purpose. Cluster flies prefer to be outside in comparison to the house fly who wants to share your lunch with you.

What are cluster flies?

Cluster flies look similar to a house fly but are slightly larger and darker in color; they have distinct irregular light and dark areas on their abdomen and short gold colored hairs on their thorax. Cluster flies do not sting or bite and are not considered to be dangerous and are considered to be nuisance pests. They also do not spread as much bacteria as other flies because they do not lay their eggs in human food but rather near earthworm burrows.

So, why do you I cluster flies in my home?

As the temperatures begin to cool down in the fall, over wintering pests like cluster flies seek protection from the cold temperatures.  On warm days you will finds them on sunny sides of the home (often the south side) where the wall voids heat up along with the attic space. As the temperatures begin to warm up, cluster flies emerge trying to get back outside where they belong.
