I know about bat rabies, nothing spreads rabies more than bats. I doubt this thing is going to fly so my idea is just to move the whole sheet of OSB to somewhere where the cats can’t reach it.
Between my bats and the chimney swifts I don’t have many mosquitos in the summer. For some reason I don’t have any barn swallows.
Mmmmmm....I loves me some Alpha-bat soup!
