You can't remove bats? Then what do you do if you're in a situation like hotdot?
There are conservation groups you can contact who can help and try to relocate the bats, but sometimes the bats just don't want to move, so you can't force them.
Ultimately you have to put up with it or move away. The law is on the side of the bats.
You could kill them or forcibly remove them, but you'd be facing fines and other punishments if caught.
