Help! Bats in the attic!?

I just recently discovered that I have bats living in my attic! How can I get rid of them? Any suggestions would be helpful!

Answers:
Bats usually are the type of animals that freak or gross people out. But they're really neat little animals. They're good for keeping the mosquito population under control. What I did was build a bat house and hang it near my garage then chased the bats from my attic and sealed the area where they were entering. Now they live outside in the bat house and no longer fly around my daughters bed at night. It scared her but it was really cool to see.
