Cluster Flies

Cluster flies can be very troublesome in winter months, particularly with warmer winters, these flies are becoming active through the winter, not just autumn and spring. Cluster flies breed in fields in the summer and hibernate under wall cladding and in roof voids in the winter.

Cluster fly can be dealt with in several ways, the most effective is using an electrified grid cluster fly killer (we sell specially adapted ones), but if you have more than one roof space this can be very expensive, but you do collect the dead cluster flies! They are not lying all over the roof. If the cluster flies are under wall cladding you can use insecticidal dust injected behind the cladding with our dust bellows.

Insecticidal smoke is widely used as a cheap one-off killer in roof voids, low cost cluster fly control but no ongoing protection. We also have the Cluster Buster Window Trap that is imported from Powder Trap in Canada. This fly trap uses egg shells as a quicksand and in particular, cluster flies will find this cluster fly trap very appealing!
