Almost exactly a year ago I had a bat in my house. No idea how it got in. I think I posted the story on here, but since I couldn't find where he was hiding, I just stayed at my parents until he died Sent him to the health department for testing, and got the results back the morning we were leaving for Italy. I don't care how harmless or beneficial they're supposed to be (goes for spiers, too), they don't belong in my house and if they enter that space, they'll pay with their lives!
