Little assistance to just double check with the pro's.
Hole:
This is the only sign of life up there. Under insulation on top of sheetrock:
Homeowners don't believe it's only mice that's making all the racket. These pics were taken directly above there bedroom where they go to bed around 7:30 and hear "the scratching, nuts rolling and running". Tried to explain just lots of mice (which I don't do, got a friend whose an exterminator). Also hole after hole thru the blown in and some small trails on top w/mice poo in them.
Questioned myself at first, thinking flyers or roof rats but no sign I can see.
On opposite side of house there was also a gap about 4" long and 1" height but wood was flexible at the area.
Homeowner said he seen squirrels walking along the brick wall in that vicinity so I set cage on roof. 4 days nothing! Yesterday he discovered wood and chipped paint, in the back corner, on the ground where above pics where taken. I searched the whole attic and exterior the first day. Back yard's fenced and locked up when I've been checking daily until today, so I would never notice that hole.
What = mice, When = mainly early evening, Where = attic, Why = warm and dry. Is this right Jonesie?
I'm positive it's all mice. What do you think?
