Cluster flies hibernate in large numbers during the autumn months, entering buildings through sash windows and small holes in the walls, preferring cavities, roof spaces, attics and dormant rooms in which to overwinter. They appear again in the spring, often congregating at windows and flying slowly around the home.
Cluster flies are important to eradicate because they will return in large numbers year after year if not properly treated.
TREATMENT – After a survey and risk assessment has been carried out, our Pest Control Technician will decide on the best treatment to suit your situation. This generally consists of a fumigation treatment or a residual spray application.
