Cluster Fly Treatment £75
Cluster flies can be a nuisance due to the large numbers that can suddenly seem to appear in a loft or around windows and in particular, around Velux windows in lofts.
Treatment generally involves a quick survey to rule out any bat activity and check for open water tanks or pilot lights. After this lofts are fogged with quick knock down insecticide and window frames are treated with a long lasting residual insecticide that remains active for months.
We use a professional fogging machine that disperses a liquid insecticide as a space spray between 15 and 40 microns. At this size the droplets can remain suspended in the air but are not repelled from the insects.
We never use pyrotechnics or “smoke bombs” in peoples homes and would strongly recommend against purchasing such products.
