Cluster Fly Loft Fumigation in Hillingdon: what we see locally
Cluster flies breed in grassland and pasture, and Hillingdon has more than most of London. Farmland around Harefield, Ickenham and Harlington, the meadows of the Colne Valley and the open land around Ruislip and Northwood all support large numbers.
In autumn, the adults look for warm, sheltered places to spend the winter, and the lofts of nearby houses are ideal. They crawl in under roof tiles and through gaps at the eaves, then appear at upstairs windows on sunny days. Our fumigation treats the whole loft space.
Homes in Harefield, Ruislip, Ickenham and Northwood are the most often affected.
