Hi guys I’ve seen a bat in my basement 3 separate times over the last two weeks since we’ve moved into this house. Everytime I’ve seen them or possibly the same one 3 times, it’s attempted to fly back up into the insulation at the corner of this basement. I found this on the outside. I can see insulation thru this hole. Was just going to install a one way bat thing over this home? Any reason I shouldn’t do this. I’ve never seen them anywhere else in the house. I’m in southwest Wisconsin.
