Clusterflies

Hi,

 

I am new to the group.  I have a problem with Clusterflies in my house, which backs on to open land regularly grazed by cows and sheep.  Every autumn and spring, the clusterflies gather in the house in large numbers, and the only way I can deal with them is to regularly fumigate in the loft spaces with smoke bombs and spray.  I have two questions:

 

-  Is there a natural predator for clusterflies that would help to reduce the usage of insecticide?

-  My understanding is that the flies return every year because of following pheronomes.  Is there something I can do to eliminate this pattern?

 

Thanks!

John

    Hi John,

     

    In my experience it can be difficult to deter clusterflies and there are frequently several species present. That said in homes they often disappear as mysteriously as they appeared. I could only suggest the use of aromatic and heavily scented sprays, citronella for example, to try and mask the sent that the next generations returns to.
