Brian just curious how did that bugger get in the wall did you see any holes in the top wall plate. Plates are double 2X4’s would be much for a squirrel to make his own hole must have been a man made hole already.
BTW good images the person with a camera in his hand will go far in this business when they see something strange and goes the extra mile to discover why
This location was a finished walk-out basement. The ceiling was a dropped(framed) ceiling. From the garage side there were several openings for plumbing, HVAC ducts, etc… The buggers were getting in around the lines from the compressor, then up into the cavity with the dropped ceiling. I couldn’t directly see the top plate at this location, so I’m assuming there was a void big enough for them to drop down into the stud cavity.
I’m assuming they were actually stuck in there. As I was getting them out, they really wouldn’t climb up the inside of the cavity.
