Having problems with cluster flies?
Cluster flies depend entirely on earthworms for their larval development. Female cluster flies lay eggs near earthworm burrows, allowing the larvae to locate and feed on their hosts. While they do not pose a direct threat to human health, their behaviour creates a significant nuisance, especially in homes and commercial properties.
Additional Information
Adult cluster flies emerge in late summer or early autumn. As temperatures drop, they seek out warm, sheltered areas to hibernate, often entering properties in large numbers. Lofts, wall cavities, and other inaccessible spaces provide ideal overwintering sites, making complete eradication challenging. Homeowners frequently notice cluster flies gathering around windows on sunny days, particularly in upstairs rooms. They often share these spaces with overwintering ladybirds, which display similar behaviour.
Unlike houseflies, cluster flies move sluggishly and do not breed indoors. However, their presence remains unwelcome due to their sheer numbers and their tendency to leave stains and odours on walls and window frames. Warm spells during winter can trigger activity, causing flies to emerge prematurely and move around inside properties.
Managing cluster fly infestations requires a proactive approach. Treating affected areas annually with targeted pest control measures significantly reduces their numbers. Sealing entry points, such as gaps around windows and roof spaces, limits access to preferred hibernation sites. Using insecticidal treatments in key harbourage areas before winter further prevents large-scale infestations.
For properties experiencing persistent issues, professional pest control services offer effective long-term solutions. Experts can identify entry points, apply residual treatments, and implement preventative measures tailored to the building’s structure. Regular inspections and treatments ensure that cluster fly populations remain under control year after year.
By taking preventative action before autumn, homeowners and businesses can minimise infestations and reduce the inconvenience caused by these seasonal pests.

DO CLUSTER FLIES CARRY DISEASES?
Cluster flies are generally harmless and do not carry diseases, unlike houseflies. While they are not typically harmful to humans, they can be a nuisance due to their slow, awkward flying and tendency to gather in large numbers. Although they do not pose a health risk, their presence can be disturbing, especially when they invade homes in the cooler months.

Cluster Flies FAQ
1. What are cluster flies and how are they different from house flies?
Cluster flies are slightly larger than common house flies, with a dark grey body and golden hairs on their thorax. Unlike house flies, they are not attracted to waste but instead enter homes in large numbers to hibernate during autumn and winter.
2. Why are there so many flies in my loft or attic?
Cluster flies seek warmth and shelter in roof spaces, lofts, wall cavities, and attics as the weather cools. They often gather in large groups, especially in rural or open areas, returning year after year if untreated.
3. Are cluster flies harmful?
Cluster flies are not harmful to humans or pets and do not spread disease. However, their large numbers, staining, and foul odour from dead flies can cause distress and hygiene concerns in homes and businesses.
4. How can I get rid of a cluster fly infestation?
