With more than 1,000 types of bats worldwide, it's likely that the flying mammals live near your home---or even in your home. Although bats are mostly harmless, they can become a nuisance if they take up residence in your shutters. There are several methods available for removing bats, but excluding them from access to shutters is the most accepted way to keep bats away.
Things You'll Need
- Bat box
- White paint
Wait until all of the bats have left the shutters before taking action. Most bats living in shutters are in the process of migrating, and they should be gone in the fall. Any action to prevent bats from living in shutters will be safest---to the humans and the bats---when bats are not present.
Place a spacer between the shutters and the house that allows the shutters to rest 3 or more inches away from the exterior of the building. Bats like to rest in crevices that are 3/4 inches or less, and they are unlikely to remain in a space larger than that.
Install a bat house or bat box. These can be purchased or built out of wood. These structures will provide a tight space for bats to rest. The box will provide a warm place for bats that is not in your shutters. It should be placed 12 to 15 feet above the ground.
Paint the shutters white. This will keep them cooler in the warm summer months. Bats prefer to rest in spaces that are about 80 to 100 degrees Fahrenheit.
Call a professional to remove the bats if the other options are not feasible. They will be able to remove the bats safely and for good.
Tips & Warnings
- Repellents are not known to be effective at keeping bats away. Ultra-sonic devices also do not do a good job of keeping bats away. Bats are known carriers of rabies, but the vast majority of bats are disease-free. It is still better to contact local health officials with any concerns of rabies.
