Has anyone ever tried to install a bat house to help control bugs? Pros? Cons? In the last year and a half my husband and I have trapped and released 3 bats inside our house. We live in Bangor and thought this would never happen but it did so we know they are around. Are they any good to keep the bugs away from the garden in the warmer months. I have been reading up on them and, of couse, all the "pro" bat websites say it's the way to go but I want to hear all the good and bad stories.
