Less than half of one percent of bats have rabies. Be careful, but not paranoid.

Most bats can't take off from the ground, so they need to crawl up something so they can get airborne. If you remove a bat from the house (a coffee can and a flat piece of cardboard works well), place it on the ground beside a tree, or on a wide branch. A bat on the ground doesn't mean it's rabid.

Bat homes are usually never empty, so if someone says to just wait until they fly out at dusk and then seal the opening, you will be trapping bats inside.
