Heh. A few years ago, I noticed that there was a wooden dowel on one of the valences that we inheirited from the previous owners of our house. Weird, I thought, since valances don't open or close. Also since it hadn't been there the day before. Also it was breathing. We panicked, then knocked it into a bucket, slipped some cardboard over it, took it outside and let it go. It was unhappy during the whole process. We still don't know how it got in, and we haven't seen any since.

I went to work and told a friend of mine who lives out in the boonies. You'll never believe what happened! A bat! In the house! She was very blase. "So what's the unbelievable part?" Apparently, it's not that big a deal for her. She had some sheet technique - you hold up a sheet, capture the bat in the sheet, and bring him outside. I can ask her if you need advice.
