July 8, 2016

Have you been noticing small clusters of flies swarming around your home or businesses windows? If so, you are not alone! This past week our technicians were called to a Des Moines home where the owner was experiencing large amounts of cluster flies around their window. Though cluster flies are most common and enter your home in late fall and winter to hibernate, it is during the summer that they seek warmth and attempt to get outside.

Cluster Fly Appearance

Also known as attic flies, cluster flies tend to be around 8 to 10 millimeters in length, have light and dark grey abdomens, a thorax that is often covered in short, golden hairs, and wings that overlap while at rest.

Cluster Flies Behavior

Cluster flies begin to look for shelter throughout fall and winter to hibernate. More often than not, they end up making their way into a home. Once they are inside, they will try to seek refuge in secluded areas such as attics or within wall voids. It is during the warmer months that the wall voids begin to heat up and show light. Cluster flies are attracted to light and will move towards it, which is why many homeowners will notice them swarming around their windows.

How to Keep Cluster Flies Out

Once cluster flies have made their way into a home, it can be a challenge to get them out. However, when it comes to preventing them, there are various tips and tricks to ensure they stay away. Tips include: 

  • Fill cracks and crevices in walls, door frames and windows with caulking
  • Fix/replace any damaged screens, doors or windows 
  • Install insect screening or mosquito nets around soffits or air vents
