It's quite delightful to wake up to a bat flying around the house at 3am. We haven't had a bat problem in yearsthere used to be bats in the unfinished attic before it was renovated into a finished third floor fifteen years ago. Since then we've had a bat or two every summer, coming in when someone forgets to close the door or something. In the last 10 days we've had 8 bats come into the living area of our house late at night. It's pretty easy to lock them in a room with an open window and go back to sleep but at 3, 4 or 5am that's not what I want to be doing (the cat has done his share and killed 2, though). Clearly we have a problem, and I'm beginning to think we have a colony in the wall...lovely scratching, scrambling and bumping sounds come from behind a radiator in the living room. It's a nightmare to find where their entrance is on the outside of our rambling 4,000 sqft Queen Anne, and from what I understand we wouldn't be able to plug it before the fall anyhow, at least without risking either a house full of bats or a wall full of dead bats. Where's the make-it-stop button?
