Hi HD
yes it is legal to trap here in my home state and in my Business I offer Both exclusion's and Bat Trapping and can say as any ethical trapper you don't lose Bats By Trapping them .
I do have good success in relocating the bat around lakes and farms with out touching the Bats here is a video of a Barn release and didn't lose a one.

Thing is when you offer two ways to take care of the problem and the people who sign your check chooses bat trapping and you show success in a Live Roost like I showed you in my Video you can say what you wish and the video is proof the bats are unharmed .
Like to say we don't do Bat work in June an July if possible and why I say possible is if they are getting in the living quarter's we will do it being Bats can be Rabies vector in living quarters and it is best for my customer's .
Let me know if the Video works for you it is my Face Book Page and thanks for being Passionate about bats as I am .
