Homeowners should be concerned about cluster flies in their attic due to the potential damage they can impose on the homeowner. Cluster flies, also known as attic flies, are a common annoyance during late summer in the Northeast. While they may not pose a direct danger to the structure of the home, they can attract other pests such as rodents and insects. These flies live in large groups in attics, crawl spaces, or storage closets, hibernate in the winter, and emerge in the spring. They may leave excrement spots, although these do not carry disease.
The presence of cluster flies can create an ideal environment for other pests to thrive. Rodents and insects may be attracted to the abundance of flies and use the attic as a nesting or feeding ground. This can lead to further damage to the home, such as chewed wires, contaminated insulation, or structural damage from burrowing. Additionally, the accumulation of fly excrement can create unsanitary conditions and unpleasant odors in the attic.
To prevent cluster flies from entering the home, homeowners should consider regular pest control treatments between June and August. Focusing on areas vulnerable to entry such as gutters, window seams, door frames, soffits, eaves, vents, and electrical outlets can help minimize infestations. Applying insecticides to the surrounding soil can also be effective in deterring cluster flies from entering the home. It is important to address any existing infestations promptly by contacting a pest control company for treatment and inspection to prevent reoccurrence.
It is worth noting that cluster flies do not reproduce indoors. They typically enter homes seeking shelter and warmth during the cooler months but do not lay eggs or reproduce within the home. This means that homeowners should not fear that the flies are hatching from a dead source within their attic.
In conclusion, homeowners should be concerned about cluster flies in their attic due to the potential damage they can impose on the homeowner. While they may not directly harm the structure of the home, they can attract other pests and leave behind unsanitary conditions. Taking preventive measures, such as regular pest control treatments and addressing existing infestations promptly, can help minimize the risk of damage and ensure a pest-free living environment.
