Cluster Fly

About Cluster Fly

These slow-moving flies are slightly larger than common houseflies and often gather in clusters on warm walls and windows during cooler months. Cluster flies (Pollenia rudis) lay their larvae in earthworm burrows, but as adults, they become indoor nuisances, especially in homes around Columbia and Spring Hill. While they do not bite or spread disease, their presence can be bothersome, making professional pest control a useful option for Middle Tennessee homeowners.

Cluster Fly is a fly commonly found in Middle Tennessee, including Columbia, Thompson's Station, Spring Hill, and the surrounding areas. This entry is part of our Flies identification guide.
