I once worked in an office building that had squirrels
living in the drop ceiling. We had to keep our lunches
in a filing cabinet when there was no more room in the fridge.

My relative has squirrels in the house in little homes they build for them and now has lots of mice....
They cannot see one brings in the other. I was told they discovered a mouse in the window a/c chewing on the styrofoam. I bet they are eating the wires in the house too.
