How to Prevent Cluster Flies from Entering Your Home

There is a big difference between being bothered by the odd cluster fly coming in through the door with you and finding your home filled with flies about to enter hibernation.

This is the time when cluster flies are seeking entry into buildings to bed down for the colder winter months. You might wonder whether this is a big problem. After all, if these flies are simply settling down to sleep during the winter, are they going to be a major concern?

There are worse problems you could have involving pests in your home. However, our homes are not the coldest of places to be during the winter. Cluster flies get indoors out of the worst of the weather, enabling them to sleep soundly until spring comes. When the central heating comes on and lights are switched on in darkened rooms, however, the problems begin in earnest.

Are you bothered by buzzing?

Many people associate flies with the summer months. However, if cluster flies find a way inside your property to hibernate, you can be sure you’ll be bothered by them during the winter as well.

Conditions must be ideal for the perfect hibernation period to occur. We tend to interfere with those conditions by doing unreasonable things such as turning up the heating and switching on the lights so we can see where we are going. Unreasonable, indeed.

The flies react to this by being pulled out of hibernation, if only slightly. It’s enough for them to buzz around inside our homes though, causing frustration and annoyance all winter, if we let it.

Last chance to make sure they cannot get in

Blocking entry points to your home is key here. The more places they can get in, the more chance there is of you being bothered by them. Even if you don’t notice their presence from now until February, you will doubtless notice it once they start waking up come next March.

It is always far trickier to get rid of cluster flies once they have taken up residence in your home, whether that is in a chimney, attic space, or elsewhere. Prevention is better, so look for any gaps around doors and windows that can be plugged. This also helps keep your home warmer, reducing any heat loss through these gaps – another element that can attract flies and other pests.
