Cluster flies do not present a health hazard because they do not lay eggs in human food. They are strictly parasitic on earthworms; the females lay their eggs near earthworm burrows, and the larvae then infest the worms. So more a nuisance builder than health hazard!

However, the flies are a nuisance because when the adults emerge in the late summer or autumn they enter houses to hibernate, often in large numbers; they are difficult to eradicate because they favour inaccessible spaces such as roof and wall cavities. They are often seen on windows of little-used rooms.

The first step in controlling a cluster fly infestation is to identify the primary roosting site, this is normally in an attic or loft and on a south west facing elevation. The contents of the Cluster Fly Blitz Kit should be used as follows:
1. Place the Midi Fortefog P Fumer, on a heat resistant surface in the room to be treated (up to 250m3). Read the label and directions for use instructions carefully.
2. Treat all the surfaces and soft furnishings with the Protector Natural Insect Killer as per the label instructions.
3. Treat all cracks and crevices and areas where the cluster flies are entering the buildings with Agrothrin dusting powder as per the label instructions.
