Cluster flies can be a huge problem and is something you want to get rid of before entering your home as they can leave your home uninhabitable due to the large number of flies.
During the colder months cluster flies like to hibernate in attics and in your walls. Once it gets warmer, they begin to wake from their hibernation and will head outside and return again in the fall.
