How to Get Rid of Cluster Flies Naturally 

cluster fly solutions pest and lawn

You think flies buzzing around your head in the sweaty summers are annoying, think again. You cannot fathom how much more maddening it gets when there are flies in your home in the chilly winters. With all the windows and doors closed, these flies will continue to torture you unless you do something about them.

These flies that you encounter in winters are unlike the ones that visit you in the summers. Cluster flies, are what is known as an Overwintering pest, that tend to be the ones that begin to show up in late fall and last all winters. However, the most infuriating thing about these flies is their tendency to exist in clusters, in your attics. Hence getting rid of these flies is slightly more challenging than just swatting them away with a rolled newspaper. You’ll need some help with it.

But before embark on that mission, let’s get to know these winter flies a bit more.

What We Need To Know About Cluster Flies

Cluster Flies are larger than your regular house flies and they like to lie dormant between your house walls in the winters to stay safe. Their favorite most places to hide during the winter are the attics of our humble abodes. Usually, they just lie there in clusters and wait for the weather to warm up. But that is little comfort for a person who is housing a humongous family of cluster flies in their attic.

And that is only in theory anyway. Apparently these flies cannot resist t warmth and comfort of our cozy homes and are drawn to where you are simply hanging around with your happy family.

Here’s how these little vermin look if you wish to be sure that you are dealing with a cluster fly and not a regular house fly:

  • These are larger in size than house flies and have a checkered body of either black or silvery color.

  • The younger cluster flies have a patch of hair on their lower body of light brown and yellowish shade.

  • While house flies just buzz around in speed, the cluster flies lazily flies around, which make them even more irritating. They are not so quick to run away with a shake of your hand.

  • When the cluster flies are not flying, they rest their wings in an overlapping position. House flies don’t do that, theirs remain separate.

  • House flies never cluster around, unless there is some sweet food for them. But cluster flies will form a cluster right beside your attics window or a window that is used less often.  

Once you are sure that you are being bullied and tortured by cluster flies, you can do the following to get rid of them:
