How Do Bats Get in Your House?

Bats are resourceful creatures. They like to be out of extremely cold temperatures and also away from the heat of the day. They can slip into the tiniest holes or cracks in a structure and then establish a home for themselves there. Often bats live in colonies.

Older homes are especially vulnerable to bats finding a way in, but they can come through such small spaces that virtually any house can fall victim.
