Got an RV, Motorhome, Travel Trailer or Pop-up Camper? An affordable, yet effective way to keep rodents and insects away from your unit during the cold months is to just place dryer sheets inside your unit or RV. Place dry sheets in the drawers, cabinets, around & under that bed as well as the walk ways.
Then in the spring, you wont have to keep up rodents and your RV or camper will even smell nicer.
