More information on Cluster Flies

Cluster fly problems are seasonal and occur in the Spring and Autumn. In the Spring, cluster flies emerge from their Winter hibernation and start the task of seeking suitable outdoor sites to lay their eggs and carrying on the cluster fly cycle.

We are often asked about the issue of cluster flies re-occurring. Unfortunately, the fact is that cluster tend to return to the same locations each year it is an unfortunate fact, that if you have experienced a cluster fly issue previously you will likely suffer the same fate in the future.
