Right at the top of an interior wall, inside the attice above the hole going down thru the 2x4, a rodent, mouse or rat, had eaten away about
2 to 3 inches of romex covering. The "black and white" wires inside did not have any damage. I have stopped the mice from getting in the attic. Since the metal wire is not exposed... can I just cover this area to make sure no future rodent gets to the wire???? or should this short section be replaced. thanks..
