Cluster Fly Loft Fumigation in Merton: what we see locally
Cluster flies breed in grassland, and Merton has some of south London's largest open spaces: Wimbledon Common, Mitcham Common, Morden Hall Park's meadows and the playing fields of Motspur Park and Raynes Park.
In autumn, the adults look for sheltered places to spend the winter, and the lofts of nearby houses are ideal. They crawl in under tiles and appear at upstairs windows on sunny days. Our fumigation treats the whole loft space.
Homes around Wimbledon Common, Mitcham Common and Motspur Park are the most often affected.
