In a treatment that is similar to boxelder bug and ladybug control, the application for cluster flies involves a brief series of applications in the mid to late summer. June, July and August are prime times to treat the exterior of the home with a botanical material that will kill the fly before it can enter the home to hibernate. Treatment of the outside of the home is often times adequate if we also employ light traps in the attic. Cluster flies are phototropic meaning they are attracted to light and will often be caught by the thousands in a good light trap. Sealing up holes and cracks should also be done as they are found.
Cluster flies can enter through an amazingly small space.
