Cluster flies are a large species of fly; adult cluster flies can grow up to ½ of an inch long, which is slightly larger than the common house fly. These flies are often confused with house flies, but it is important to understand that they are two totally different species. The body of the cluster fly is long and narrow. These flies are dull gray in color; cluster flies also typically have dark black and golden-colored hairs on their thorax and legs. When at rest, the wings of these flies overlap at their tips, while the wings of the house flies do not.

Are Cluster Flies Dangerous?

Unlike many other species of fly, cluster flies do not lay their eggs in the food that we eat, and are not known to transmit serious diseases to people. These flies are considered nuisance pests, but pose no real threats to people or pets. Cluster flies are a danger to the earthworm, however; cluster flies lay their eggs near earthworm burrows so that when their larvae hatch, they can penetrate the bodies of earthworms and feed on them.

Why Are Cluster Flies On My Property?

Cluster flies invade homes and other warm buildings in the late fall while seeking a place to overwinter. The attics, crawl spaces, and wall voids found inside these structures offer cluster flies refuge from the cold winter weather outside. Cluster flies become a nuisance on warm, sunny days as they emerge from their hiding spots and “cluster” around windows, light switches, light fixtures, and doors.
