Cluster Fly habitats

As the days shorten, and the weather cools, cluster flies can enter your home to over winter and can travel more than a mile to do so. They usually occupy attics and wall voids in rural areas around the Wirral . They can use the same structure year after year.

Cluster Flies can be a problem in the autumn and springtime; in the autumn they enter to hibernate. On warm sunny autumn days and again in the spring they can also be a nuisance when they begin to leave your Wirral property. Once stimulated, cluster flies seek ultraviolet light. They can be found crawling around windows, lamps and lights in vast numbers.

How to control a Cluster Fly infestation. Methods:

When active within a loft space in your Wirral property we will carry out a treatment with an insecticidal fogging machine or smoke generators. The machine breaks the insecticide down into fine particles filling the entire loft with a heavy fog or smoke of insecticide. This will kill off all active flies on contact. Subsequently, when the insecticide has dried it has a residual life of up to 2-3 weeks which will then kill any newly hatched flies that land in the treated areas. The treatment may need to be carried out twice a year for heavily infested properties.
