Just went up to the attic and (for the first time in 39 years in this house) there's a bat flying around up there.
Not sure how it got in. Had a new roof put on back in 2012. There's only two windows, screens look ok.
The house is 117 years old, perhaps there is a hole somewhere along the edge of the attic which it was able to get in through.
Any tips on getting it out?
