We are getting settled in to our winter location, the volunteer campground at a National Wildlife Refuge in New Mexico. Some of the old hands are warning us about "pack rats" which may climb into engine compartments and chew insulation to make nests. Various precautions have been suggested like leaving the engine compartment door open, stringing rope lights under the rig etc. We've also been advised to wrap wire wool around the water and sewer lines to prevent field mice from using them to get into storage compartments.
Question for the experts out there: how big a problem is this in reality, and what are the best remedies to prevent rodent intrusion in an occupied motor home in winter conditions?
