How to Winterize Your RV for Mice

Winterize our RV in storage


Since winter is often the time when mice enter a Recreational Vehicle, making some changes to your storage routine can help prevent an infestation. While mice can find their way into an RV no matter where it is parked, there is an increased chance if you store it outdoors near fields or open areas. If possible, park the RV on a hard surface away from grassy or wooded areas.


Mice may have poor eyesight, but they make up for it with a good sense of smell. Before you store your RV for the winter, clean out any food sources that could attract rodents. This includes dried food items, condiments and other items that would otherwise be fine all winter long in the RV. They serve as a source of food for mice seeking refuge in the winter. Even if you store the food in plastic bins, the rodents will find a way to chew through the containers to reach the food. The containers may slow the mice down a little, but they will not stop them completely.

Remove nesting materials such as loose fabrics, string, artificial plants, cardboard, to name a few. Any provisions kept inside may entice mice to climb in for a free meal.


Inspect the outside of your RV for any small openings or holes a mouse can fit through. Fill outside holes and cracks with steel wool or spray foam insulation. Here are a few areas to look at:

Check window and door seals to ensure they’re clean and snug.
Seal your firewalls and access holes for water lines.
Vent all propane lines to discourage insects such as wasps, bees and spiders from building nests.

According to some sources, another option is to place a cover over your RV or create a barrier using an aluminum fence around the wheels. The flashing may deter mice from climbing. The fence should be at least 24 inches tall and go around the perimeter of the vehicle.


check on your RV regularly while it is in storage, if possible. If you store it at home, walk through the RV when possible to look for signs of a rodent infestation. Starting up the engine on a motorhome-style RV can help scare away rodents who try to make a home in the engine compartment.

You may discover mouse droppings under appliances, a mouse nest in your access panel or found other signs of mice in your RV while you are parked at home. Did you know there’s a good chance these destructive pests are trying to get into your house too?  For help getting rid of mice and other pests in your RV and home, contact Pestcheck Pest Control today!
