Cluster flies are ‘two winged’ insects. They are about 6mm long with distinctive golden hairs on the thorax.
Flies belong to a very large order of insects known as Diptera, which has over 100,000 species and in general are a nuisance worldwide.
Cluster flies live outside during the summer, they are harmless to humans and are not thought to carry diseases like the house fly. Where the problem starts with cluster flies is that they will look for a warm, dry place to hibernate during the winter - this could be your loft/attic, and they can do this in vast numbers. If the loft/attic becomes warm during the winter they could emerge into the house causing a sudden problem. Cluster flies live outdoors and feed on nectar from flowers.
Cluster flies lay eggs in damp soil or rotting leaves.
Cluster flies are more of a nuisance rather than a destructive pest, and really only become a problem if they decide to use your property as their winter home.
Although you may be unfortunate and have invasions of cluster flies every year, control is easy. For an effective treatment it is advisable to contact a professional pest control contractor like (DPPM) David Price Pest Management.
Eradication starts with a thorough survey to check the size of the problem. Smoke generators, powdered fog generators or low pressure sprays are used to kill flies immediately and penetrate their hiding places and give continued protection for several months.
Results are almost immediate, also sprays can linger and continue to kill emerging flies for several months.
