As autumn and winter begin to close in  Cluster Flies start to enter homes via small cracks and unsealed openings. They are basically looking for somewhere to over-winter, and once an attic is found that they like cluster flies tend to use the same one again and again.  

Once inside they congregate, or cluster, by the thousands in attics and roof voids where they will overwinter and then depart the following spring.

Proofing for cluster flies is virtually impossible.

Having cluster flies has nothing to do with your properties cleanliness, they just choose an attic and will then continue to use it year after year until the cycle is broken. The cluster fly itself is not dangerous and is nothing but a nuisance, but large numbers of flies can mean creepy crawlies like beetles could be attracted, plus sharing a property with a huge swarm of flies is not that appealing to most people.

Exopest Ltd will treat the cluster flies with professional strength residual insecticides, killing the flies instantly and breaking the all important cycle so that once rid of them , your attic should be cluster fly free for the following years.
