Alright...there's a bat flying around my apartment. Any suggestions on how to get rid of it?

We found one in our garage last night when we came home. That was the first time it happened, and I was afraid one of my cats would catch it and try to bring it into the house. Ugh! After circling for a while it did go out the garage door. Perhaps if you open your largest window and gently herd the bat towards that wall, it will stop panicking and make its exit.
