What if I already have bats in my attic?
That's actually great! Attics often provide ideal accommodations from which bats are reluctant to move except when excluded, which is when you create a one way exit out of your attic. Several leading animal control professionals advertise that once bats are excluded from an attic, they'll try to find a new home nearby in your shed, barn, or even at a neighbor’s house. They recommend putting up a bat house or two nearby to offer the bats an option to quickly relocate when they return from hibernation. When bats are given a nearby bat house of sufficient size to accommodate their whole colony, they often move in to a house that was provided at least a few weeks prior to exclusion. This keeps the bats safe and stops them from going back into your attic. Sounds like a win/win in our book.
