nut and animals??

Hi all,

I inspected a cool room in a house. Once I opened the door, I saw this issue (pictures).

I am wondering what the hell are they, nut…animal wastes? Is a squirrel or raccon living in the house and left nut on the insulation in the cool room. Please advise.


Black Walnuts

Time to call pest control…

Walnuts gathered by squirrels for their winter food supply .
We call them Tree rats in my area.

But, I checked all around the house. I can’t find any hole to get into the house.

But I had checked all the exterior, I didn’t see any holes to get into the building.
