I had a batty room mate the other night. It snuck in some small opening, probably along the edge of my sliding screen door. It was greeted by my cat, and the chase and flapping of wings woke me up. I flipped on the light switch and met my roommate for the night: a Big Brown Bat!
After hustling the cat out of the room and closing the door to confine it to my bedroom, I snuck out to get a long pole, namely a skylight crank pole. I opened the balcony door and lowered the upper sash of the double hung window to give him two escape routes. I turned on the balcony light, hoping to attract moths to lure the bat out.
But my bedroom ceiling peaks at 10 feet high, and the bat just wouldn't fly low enough to fly out the window or door. Every time I nudged him with the pole, he just flew a few circles around the high ceiling and would land and hang upside down at the peak of the ceiling.
It was 4:00 in the morning and we were not making any progress, so he decided to just stay the night, hanging high at the ceiling peak. We left the door and window wide open just in case he wanted an early check-out.
But in the morning, he was still perched in the same place. We tried a new tack: we put a towel on the end of the pole and when we put it near him, he clutched onto the towel. We quickly stuck the pole outside the door, and the bat took off and landed on the balcony rail. After a quick photo, he was gone, hopefully returning to his bat house on the front of the garage.
Don't worry - the cat is okay and we're okay, albeit a little tired from some lost sleep due to our uninvited house guest.
