How to Kill Flies in an Attic


Unfortunately for home owners, flies seem to enjoy the thrill of sneaking into a warm attic during humid summer months. Regardless of how often you take out your garbage, how frequently you sweep or have indoor pets, you may find that flies have nestled into your attic with no intention of leaving. Flies are lousy house guests, but there are several steps to show these pests just how unwelcome they are.

Things You'll Need

  • Insect fogger
  • Maintain the exterior of your home in an effort to prevent flies from entering your attic. While you can kill flies that are inside your attic, it is much easier to prevent them from coming inside. Keep attic window screens on at all times and try to keep attic windows closed.

    Make sure the tiles on your roof are sturdy and in good shape without any small holes or spaces that would enable flies to enter. If you notice any cracks or holes in the siding of your home near your attic, repair these immediately.

  • Use an insect fogger to kill large amounts of flies in the attic. Follow directions on the product. Clear out any important items that may be laying around loose. While a fogger is effective, it can leave a smell on loose items in the enclosed space. You may need to use the chemical insect fogger several times to kill all of the flies.

  • Apply sticky fly traps in the windows of your attic. Sticky traps are thin, long clear strips with double-sided adhesive. In addition to windows, apply the strips to areas the flies seem to permeate. For example, if you notice a lot of flies gather on the floor near a certain box, apply a strip to the floor.

  • Place fly bait traps throughout the attic. The traps attract the flies and kill the bugs when the flies eat the poison. One of the primary advantages of fly traps is that you can place the traps under furniture, on window sills and in other hard-to-reach places throughout the attic. Bait traps do not leave residue, so there is minimal cleanup when you are finished.
