We put a bat house up about four years ago and until last night we had not had any confirmation that there were any bats living in it even though we had seen some around the house from time to time. But, after last night we decided to go sit outside tonight and wait and watch for them to come out. We were not disappointed and DoA filmed it. He did edit some of the time out when there were no bats exiting the house. Here's the video.
