Bat Friend Found

When I went up in the attic to finally put away the last of the hand-me-downs from Taesen, I found our resident bat. First he was flying around chaotically, then settled in the corner, which, based on the droppings, is his home base. We'd been wondering where he was coming in, and now we know. Still not sure how to fix the problem. And honestly, we'd just let him live there if it wasn't for the poop.
