I don't know where my bats live. When I had my 'puter in the attic, though, I would see them swooping outside my window every nightfall. Gaaack!

One morning I found one hanging under my garage eaves. I was pretty concerned -- none had never slept there before and a disoriented bat is a potentially rabid bat. But s/he slept there all day and was gone at dusk, never to return.

Maybe was just seeking new digs and decided to try out the garage and found it was too high traffic and brightly lit an area for a permanent home?

eating their own body weight in insects each night. And regarding the fruit-eating varieties of bats in the tropics, over 300 varieties of fruits depend on them for pollination. They are also rapidly disappearing, in part due to the spread of the white nose syndrome disease in U.S. caves and mines. It's been estimated that the little brown bat will soon disappear in the eastern United States.

Did you know about the safe haven for bats that was built in Tennessee? It's an artificial cave that can be disinfected, with the aim of keeping the bats safe from white nose disease.

Here is another sort of bat refuge here in Tennessee:

Ingredients in witches' potions (wool of bat). I find them fascinating and almost brothers and sisters because I'm a long-time caver.
