Can Flies Enter Through an Air Conditioner?

A common question that we all have is, “Can flies enter through an air conditioner?” Fortunately, the answer to this question is “yes!” It is possible for flies to enter your home through a small opening. They are attracted to light and can even squeeze into the smallest gaps and voids of your AC unit. If you find a gap, it is a good idea to fix it immediately so that no more flies can enter.

Another reason that bugs will enter your air conditioning unit is the cool temperature. While you may be comfortable in 80 degree heat, the air conditioner can actually attract more than just flies. Because AC units are “sucking” air, bugs will be attracted to the cooler temperature. Some predators will hang around the window unit, waiting for prey to fall. Other pests, including cockroaches, will seek out the cooler temperature in your home.

If you notice a small hole near your AC, you can seal it with caulk. However, this method can leave a tiny gap that allows more bugs to enter. Choose a caulk that won’t attract any new pests, and make sure it is easy to remove if necessary.

Another option is to make sure your AC has a window that covers it. This will prevent flies from entering the window. Also, make sure you have a proper ventilation system. This will help keep air circulating and reduce the amount of CO2 that enters the home. You can also seal any holes in the vents of the AC unit.
