Ron,
... put down the infrared camera ... now back away from that camera ... hands up on the wall ... BOTH hands ...
The infrared camera, which you bring up every time you can, *is only a diagnostic tool* which is intended to help the inspector with their inspection.
It is not a 'show and tell tool' ... 'hey, look, bees in the wall' ... or ... 'hey look, live animals in the wall' ... it is intended to make the inspector go 'WTF? How'd they *get in the wall*?'
That is the question.
I'll check back in the morning (going to bed now) and see if you can figure out "how" (i.e., 'why') the squirrels got in that wall.
Somethings not right, somethings missing, where and what ... that is your mission should you chose to accept it (or anyone else accept it).
Don't treat the infrared camera as though it were an X-ray, it is not (however, even an X-ray would only serve the inspector for diagnostic purposes), treat it only as a "very expensive infrared thermometer which show visually instead of digitally".
I used my infrared camera every day in my inspections, but it was for diagnosis, not 'hey, looke what I found' (although, I cannot downplay that as it *certainly did help my inspection business* - that was the best marketing tool I ever bought - I did not market, period, word of mouth - and that certainly got my clients talking to their friends and neighbors, and *that* was my business). But the infrared camera is 'just a tool', you have to be able to know what to do with the information it is feeding you. Otherwise, it is either worthless or just for 'show and tell'.
I'll check in the morning.
