I used to ALWAYS get bats in the house the first 2 weeks in August (the hottest wks of the summer), and they'd terrorize me and the cats at 1a.m., AAAAGGGHHHH !! and the scene was right out of a comedy flick, the bat flying around the house, the cats and me chasing the bat, me equipped w/a net, having the net get caught on ceiling fan, cats jumping, me screaming (windows open, NO ONE COULD HEAR ME....scary thought of getting killed, and no help)
Sadly, our bat population has diminished by nearly 2/3rds ;( , haven't had a bat in the house in a few years now.
