cluster flies
Cluster Flies are irritating, unsightly and unsanitary, which is why finding an infestation is worrying. Cluster flies are 8mm long and are a dark grey colour, with small patches of gold hair on their back and long wings. Appearing in spring, cluster flies will begin to lay eggs outside and will hibernate in your home in winter, around August time. Cluster flies make their way into the home through doors and windows, around loose electrical outlets, under roof eaves, openings around cables, pipes and through vents. Throughout Autumn, you will find these in large congregations hibernating in attics, sheds and garages but as soon as spring comes around, they will make their way back outside.
How to identify cluster flies
The obvious sign of a cluster fly infestation is to see a large quantity of lame or dead flies. It’s also very common to find them in your attic, in velux or roof windows, in sunken spot lighting or under insulating felt layers. Cluster flies typically return year after year, unless eaves and other entry ways are adequately sealed.
What are the risks/diseases of cluster flies?
Cluster flies have no direct health effects on humans but the sheer amount of flies produce a noticeable amount of excrement, that’ll stain walls, floors and belongings, and produce a strong and unpleasant odour.
Cluster flies are an annoyance in domestic settings but pose a big threat to commercial settings, such as restaurants. Cluster flies can contaminate food preparation areas and even food, so it’s important to stop preparing food until the pest problem is completely eliminated. Otherwise, it’s likely they will face fines, a bad reputation or worse, shut down by health and safety officers.
