I get them in the house, now and then. I don't know how the little devils get in, but they get my dogs all worked up and it always seems to happen when I'm in a nice, deep sleep. It's gotten to the point where I always know what's going on when the dogs all go nuts at midnight. Another blasted bat! Anyway...when they fly, they have to drop downward to start out, so you use that to your advantage. If he's on a wall or even the ceiling, use a broom or dustmop to dislodge the little critter and catch him in an old towel. You might need help. Otherwise, if he's low enough, on a wall or something, just put the towel over him and wrap him up in it and take him outside. I've done it four or five times and it only takes a few minutes. I haven't been bit, yet. One more point. Don't let yourself be freaked out about it, it's just a mouse with wings. They won't attack you, all they want is to get out of your house. You just help them achieve that goal.
