When I worked as a walk-through technician at a large RV dealership, I was responsible for giving new RV owners their orientation. During this time, I learned a trick to help keep insects out of the back of water heaters and refrigerators. Simply place a section of a dog’s flea and tick collar in the water heater and refrigerator service areas. One average-size flea collar is enough for both areas. I used small adhesive-backed plastic clips to hold the flea collar in place, though you could probably use duct tape as well. The flea collar will repel insects for the entire camping season.
