The Cluster Fly is commonly seen in the fall, winter and spring, especially on warm days. During the late summer, female cluster flies lay their eggs in the soil. Within a few days, the eggs hatch and the larvae emerge to feed on earthworms. In late summer and early fall, when the nights start to turn cold, adult cluster flies seek shelter inside homes, where they remain for the winter. Sometimes, called attic flies, cluster flies often enter a home by squeezing through tiny cracks and weatherstripping.
How to Get Rid of Cluster Flies
The best defense against cluster flies is a pest application applied by a cluster fly pest control professional in late summer and early fall – before the flies enter your home. Therefore, the best time to treat your home for cluster flies is between August and October. While applications can be made on the interior of the home during the winter months, it is not recommended due to limited success.
