What Is This Cluster of Flies on the Windows of my Springfield Home?
October 21, 2016
If you’re experiencing groups or large flies on your windows during the fall, chances are – they are cluster flies. Cluster flies hibernate in groups in the voids of walls or attics during the winter. You might find cluster flies on your windows in the fall because they enjoy the warmth of the sun. When the doors or windows of your home are opened, they will attempt to get inside to wait out the winter where it’s nice and warm.
Facts about Cluster Flies
Cluster flies live in all US states except for states bordering the Gulf of Mexico. You can also find them in Canada and Europe. They stick together in groups consisting of a few dozen flies to thousands.
Cluster flies do not bite animals or humans, so you don’t have to worry about insect-borne illnesses or stings or pain as a result of a cluster fly. They do not swarm around garbage or food the way other flies tend to do.
Cluster flies mate in the spring. Female cluster flies lay an egg in the soil near an earthworm. When the egg hatches, the larva enters the earthworm and eats the earthworm from the inside out. The entire process takes 27 to 39 days for the cluster fly to change from egg to larvae to adult fly.
Cluster flies are large, noisy flies that measure about 3/8-inch long. When a cluster fly lands on something, it leaves behind a greasy spot; and if you squish it – it will release a scent of buckwheat honey.
Home Problems with Cluster Flies
In the spring and summer, you will probably find cluster flies hanging out outdoors in areas like fields – where there are plenty of earthworms. Adults eat flower nectar.
Cluster flies will travel as far as a mile to find the perfect place to spend the cold winter months. If you leave windows open during the fall months their search for that perfect place will be over and you will be left with one more thing to worry about this autumn.
Once in your home, they go into semi-dormant style hibernation.
