I own a 2015 mirage in Florida and for the second time in 2 months one of the harness has been chewed by a squirrel, has anyone else had any problems with this and what did you do to solve it?

I have had people tell me to put moth balls in the engine compartment but I see that the fumes from these can be dangerous to humans, other places suggest usinr fox urine pellets around the place you park. I'm open for suggestions.
