I used to have one over the back door until something killed it. I found this one in the greenhouse yesterday evening. I had already shut the doors for the night so it was stuck in there.You have a bat in your belfry?
We have one that likes to sleep over the front door. We are trying to discourage it. I have enough poop to clean up.
It moved. I did not see where it is hiding this morning but there was no way for it to get out.
