How to Prevent Insects From Getting in Through Window Air Conditioners

If you’re concerned that flies and other insects can get in through a window air conditioner, the first step is to seal the unit tightly. This can be done using duct tape, cardboard, or caulking. Another effective method is to install an air conditioner bug screen over the exterior vents. The screen creates a smaller mesh to prevent intruders from gaining access to the unit and will prevent the AC unit from overheating.

You should also check for any gaps in the seal or screen of your air conditioning unit. These gaps are common entryways for flies. If you notice any of these gaps, you should immediately repair them. Alternatively, you can simply hang a fly sticker on each side of the window.

If you want to prevent bugs from getting inside your home through your window air conditioner, you should keep the window closed during the day and seal the unit at night. Then, make sure the vents and exhausts are clean. In addition, you should cover up any food that is left out in the open to attract more insects.

Another way to prevent bugs from getting in through window air conditioners is to make sure the seals on the sides of your air conditioner are tight. Cracks in these areas are common entry points for drain flies. To keep the air conditioner from becoming a breeding ground for flies, you can seal the cracks with duct tape or sealant tape. You can buy sealant tape at a hardware store.
