The common brown bat of North America can live up to 32 years. Bats are the only mammals that can truly fly. The smallest mammal in the world is the bumblebee bat of Thailand that weighs less than a coin. On the rare occasion that a bat should become confused and fly into your home you should not panic. Instead, think of the bat as an airplane.
Airplanes seek the widest areas to fly.
Stay out of his flight path which is the middle of the room. Open a window or door, draw up a chair and sit next to a wall. You can simply watch him fly out. In the worst case scenario a bat will lite on the wall. This occasion is so rare it should be celebrated.
