Bats in the House

"BCI receives more requests for public information about bats that have slipped into homes and other buildings than any other topic.
And most of those telephone calls wind up with our resident expert, Science Officer Barbara French, who also lectures on the topic to groups ranging from public health officials and veterinarians to police officers.
As part of those lectures, French recently developed a short video (about ten and a half minutes) that demonstrates exactly how to capture and remove wayward bats from homes without harming the bat or yourself.
It also shows likely entrance points for bats and offers tips on how to exclude bats and keep them from returning.
This video may be viewed, free, on BCI’s website at www.batcon.org/binb/. In addition to the video, you’ll also find lots of other valuable information about dealing with unwelcome bats that venture indoors."
