Exclusion is a process we use that provides the bats living in your home with a one directional exit point. At night when the bats wake up to feed they will be able to exit the home, but they will not be able to return. We use this method because it is the most effective and humane way to evict the bats from your home. It also helps to prevent bats from getting trapped inside of your home. The bats that may be living in your home are very small, and can get into a space only 3/4 of an inch wide. Because of this we must be very thorough during an exclusion, and make sure we don't miss even a single small crack. After an exclusion we generally ask that you wait a minimum of two weeks before you call us about hearing any scratching, or bat noises. The reason for this is because bats are lazy animals, and not all of the bats in a colony will leave the attic every single night. Some of the colony will sleep for an extra day before deciding to go out and feed. Because of this it can take several days before all of the bats leave on their own, it depends on the size of the colony. Rest assured though, they will all be gone, after all we guarantee our work.
