How to get bats out of a wall
A bat infestation can be a serious problem. In many places bats are protected, and cannot be removed if they have set up a nursery until the young can leave. First confirm that your infestation is indeed bats. Visual confirmation is always best, but another sign will be chittering that starts around dusk and then quiets down. Bats leave at night, whereas rats, squirrels and mice will wake up at dusk, but run around inside your walls. If you do have a problem with bats and believe they have infiltrated your walls, getting rid of them is not an easy task. Not only is it hard to get them to leave for good, but bats can get trapped inside walls and die there. Start by inspecting your walls for cracks that could allow entry. These can be from the outside, or from your attic.
Your chimney and Central air vents can also allow for access to bats. You can identify the entry ways by the dark oily markings that will be left behind. Rats, mice, and squirrels will leave hard, dark, rice shaped pellets. Once you have identified their bat “portals” watch to see when they leave the roost. Bats will exit sometime around dusk to feed. Once you are sure of the exit times you can confirm that no bats or pups have been left behind. Now you are ready to keep them out. While it is not absolutely necessary, it is recommended that you spray the area with a commercial bat repellent. There are a number of varieties on the market today. Many professionals claim that dog or cat repellent will work just as effectively. When applying any repellent, keep in mind that bats are mammals…
If the repellent causes an adverse reaction in bats, other mammals like your pets or family could be affected as well. Once you have sprayed following the directions on the package, completely seal any and all openings that you found whether or not the show signs of use by bats. Applying a layer of fiberglass insulation around the area as a finishing touch is another deterrent to the creatures. The fiberglass is an extreme irritant to their delicate skin and membranes. Once your bats cannot return, they will find another place to roost. To avoid another infestation, properly inspect and maintain the exterior of your home. If bats are common in your area, consider putting up a bat box in your yard offer these natural exterminators an alternative to your home.
