Cluster fly is often confused with the common house fly, cluster flies are roughly the same size. Cluster flies often appear when a small animal or mouse dies in a wall void.
Unlike other fly species, cluster flies only hibernate in winter inside of a structure. During fall or spring months, these flies often emerge, particularly on warm, sunny days thinking that spring has arrived. You may notice them on the outside of your home at these times. The flies appear at windows buzzing and “clustering” around the home, often Advanced Wildlife Control is called to help treat during these times. Cluster flies can become a problem in virtually any structure or home.
Cluster flies find dead or decaying animals and lay their eggs on them. The eggs will eventually hatch into larvae (a.k.a. maggots) which feed on the carcass. This can be a benefit at times when it’s not possible to cut the dead animal/mouse out of the wall voids. The maggots will eat the body and help reduce the dead carcasses odor. The flies will suddenly appear, in large groups, throughout the house looking for exits near your windows.
Cluster flies breed in the ground outside of buildings during the warm weather using earthworms as a food source for the immature larva (maggots). The flies later pupate then hatch as adult flies. Sometimes these flies begin to migrate indoors finding any small cracks or crevices that allow entry into structures.
Cluster flies can be a huge nuisance to our homeowners in southeastern Wisconsin. They can leave stains on walls and curtains in your homes. Also they can carry a disease and can contaminate food when landing on it.
Advanced Wildlife Control – Cluster Fly Control Methods:
We use different types of control methods when it comes to flies depending on the area that is infested. Often an outside spray during spring and fall can reduce the cluster flies population to a minimal. We offer a spring and fall outside application to your home or office to reduce fly activity. Sensitive areas are can be treated with light traps or even fly abatement stations.
