Cluster flies are not a health risk, they do not spread disease and they do not lay eggs in your house. But they are a nuisance because they come in large swarms. You will notice them as autumn turns to winter, when they come inside to hibernate, and also in early spring when they leave.
Cluster flies like to congregate in their hundreds in loft spaces and other encloses areas. Our cluster fly smoke bombs will deliver rapid knockdown once it is diffused and reach all areas of the room even those small crevices. Our fumers are available to buy in different sizes depending on the size of the room and infestation you have.
