we have been hearing something in the attic lately. sounds bigger than a mouse. we only hear it at night. i went all around the perimeter and can't find any signs of entry. house is a 1 story brick ranch with a ridge vent and gable vents. my question is what would be coming in the attic on a 20 degree night? do squirrels move at night? we got schit tons around here. chipmunks? lots of them too.
