Rat/Squirrel in wall (from cellar?)
There is a rat or squirrel (not sure which) in an exterior wall on the 2nd floor.
I can't find any entry points on or at the roof, so I'm not sure how they are entering the attic or wall.
There is an unscreened area of the crawl space under the house, though.
Is it possible that the critters would enter at the ground level and clijmb up 10' or so?
Thanks for any advice.
