Mice in the winter months

Winter is coming! And so are the mice, seeking warmth and shelter in your RV.

The University of Georgia has research that tells us that it only takes a little crack to invite these unwanted guests, especially as they leave their outdoor homes in search of places to nest during the cold winter months.

Remember, maintenance is key! Continuously inspect your RV for signs of mice, especially during winter. Make sure to monitor and address any new openings or evidence of mouse activity.

Why You Should Winterize Your RV

Winterizing your RV is a crucial step in ensuring a mouse-free experience during your off-season. RV campers understand that preventing mice from entering the vehicle is vital for a safe and enjoyable trip.

Mice are attracted to warm, cozy spaces for shelter during colder months. Simply put, an unused RV is an open invitation for these critters to seek refuge. By winterizing your RV, you’re essentially “closing the door” on potential rodent infestations. This process involves draining water systems, emptying storage compartments, and removing any potential food sources.

Now, you might be wondering, how does winterizing actually prevent mice? Great question! When you winterize your RV, it’s not just about preparing the vehicle for harsh weather conditions. You’ll also be addressing key areas that could potentially harbor these unwanted guests.

By diligently addressing all these aspects during the winterization process, you’re making your RV a less desirable habitat for mice.

Of course, it’s important to stay on top of RV maintenance throughout the year! Regular cleaning, inspecting for damage, and ensuring proper storage are all essential. These efforts will make your RV less attractive to mice and other undesirable invaders in the long run.

Temperature Factors

Mice love warmth and winter is their favorite season to seek shelter in cozy spots like your RV. With the temperature dropping outside, it’s the perfect time for them to seek refuge in a warm and inviting space. So, winterizing your RV is essential to discourage these critters from cozying up in there. By sealing all potential entry points and making the RV less welcoming for mice, you can considerably reduce the likelihood of an infestation.

Food and Waste Attraction

Mice are always on the lookout for food sources, and even the tiniest crumbs may draw them in. Make sure you do a deep clean of your RV, removing any food residue and waste before storing it for the winter. This will not only help keep the space spotless but also make it less enticing for hungry rodents. Remember, a clean RV is less likely to attract these unwanted guests!

  • Properly store food: Seal food containers and avoid leaving open packages.
  • Clean eating areas: Wipe down countertops, tables, and floors where food might have been eaten.
  • Remove waste: Dispose of trash and food waste in sealed bags outside the RV.

Cracks and Openings

Oh, the weather outside is frightful, but your RV is so delightful! Unfortunately, mice agree and can enter through even the tiniest of cracks. Inspect your camper thoroughly for any potential holes or gaps where these pesky critters may find their way in. Seal it like you mean it with materials like caulk or Red Devil 0310 steel wool before the cold comes, and make sure all doors and windows close tightly!

Plumbing and Wiring

Mice have a knack for squirming their way through plumbing systems and taking advantage of wiring entry points. It’s time to channel your inner detective and inspect the camper’s plumbing and wiring areas for any signs of mice trying to infiltrate. Regularly check for loose or damaged wires and make sure to seal any gaps or holes around pipes.

Bedding and Furniture

Who doesn’t love a cozy bed or a comfy sofa? Mice are no exception, except that they don’t pay rent! Make your RV less inviting to these uninvited guests by storing bedding and cushions in sealed plastic bins or bags when not in use. Additionally, vacuum and clean your furniture regularly to remove any food particles or nesting materials mice might be drawn to.

Measures for RV Winterization

Now, winterizing your RV doesn’t just mean sealing up any small openings! It also includes proper engine and plumbing maintenance to reduce the risk of burst pipes or system failures. Here are some helpful tips for keeping mice at bay while you winterize your RV:

  1. Clean your RV thoroughly before storing it for the winter. Mice are attracted to food debris and other nesting materials – so make sure your RV is spotless!
  2. Seal all openings, even the smallest ones, in the exterior and interior to keep mice from sneaking in. Things like weather stripping and expanding foam can be effective.
  3. Utilize natural repellents, such as peppermint oil, near potential entry points to deter mice from entering your RV in the first place.
  4. Regularly inspect and maintain your RV during the winter. This includes checking for any signs of mice, ensuring that repellents are still active, and topping off fluids as necessary.

Proper RV Storage Preparation

Choosing the right location and method to store your RV during the winter months is key in keeping mice out. Here are some RV storage tips to make it less inviting for mice:

  • Store your RV on a hard, level surface with good drainage to avoid damp areas that attract rodents.
  • If possible, elevate your RV using blocks or jacks. Mice prefer to stay closer to the ground, so get creative with your RV storage!
  • Avoid parking near tall grass or shrubbery, as these provide ideal hiding places for mice.

Water System Winterization

Drain and bypass your water heater. Start by turning it off and allowing it to cool, then drain the water from the heater by removing the drain plug. This prevents any leftover water from freezing and damaging the tank!

Use RV antifreeze in your water lines and holding tanks. Flush out excess water using compressed air or a water pump converter kit, then pour non-toxic RV antifreeze into your fresh water tank. Remember to, pump the antifreeze through all your faucets, toilet, and shower until you see the pink liquid coming out. This will protect your pipes from freezing and prevent leaks!

Prestone Waterline Antifreeze is a great option for winterizing.

RV Interior Winterization

Inspect for any cracks or holes. Mice can squeeze through the tiniest of openings, so it’s important to examine and seal up any gaps using expanding spray foam or aluminum foil. Don’t forget to check under sinks, around plumbing, and inside storage compartments!

Remove all food and clean thoroughly. Keep mice from getting into your RV by eliminating their favorite snack; food! Remove perishables, clean surfaces, and vacuum floors to remove any crumbs!

Add natural repellents. Place peppermint oil-soaked cotton balls in areas where mice are most likely to enter. These methods are more natural and safer for homeowners who want to avoid chemicals.

External RV Winterization

Check and seal exterior openings. Examine your RV’s exterior for any gaps or holes, especially around vents, and fix them using expanding spray foam or aluminum foil. Sealing these spots will create a barrier against mice and other critters.

Protect your battery. To prevent damage from freezing temperatures, remove the battery and store it in a cool, dry place. This practice can also deter mice, as some may chew on wiring in search of warmth or nesting materials!

Elevate and cover your RV. If possible, raise your RV off the ground and use wheel jacks to distribute weight evenly. This reduces the chances of a critter, like a mouse, easily accessing your vehicle. It’s also a great idea to cover it with a breathable, high-quality RV cover to prevent moisture buildup and deter mice.

Impact on the Cost of RV Maintenance

Winterizing your RV is not only a great way to protect your investment from harsh weather conditions, but it can also help prevent mice infestations during those colder months! Mice just love finding cozy, warm places to nest, and an unused RV can be the perfect shelter.

By taking the time to properly winterize your RV, you can prevent costly damage and repairs that may be caused by these pesky rodents. For instance:

  • Mice can gnaw on wiring, which could lead to costly electrical issues.
  • They can damage insulation and fabric materials, causing decreased energy efficiency and unpleasant odors.
  • Mice can even create leaks and pathways near pipes and hoses, leading to water damage and mold growth.

By properly winterizing your RV, you’re not only preserving its functionality but also saving yourself from potential headaches and expenses caused by mice infestations. So remember, taking the time now to winterize and maintain your RV can pay off big time later when you’re back on the road, rodent-free, and ready to enjoy your home on wheels!


Okay, that’s all the info we have for you…for today!

Winterizing your RV is a crucial step in preventing mice from making a cozy home in your vehicle during the colder months! These little critters can cause significant damage to your wiring, insulation, and other components, so keeping mice out of your RV is essential.

Following a proper maintenance routine can also help keep your RV mouse-free. Clean your living space often, and pay special attention to areas that could harbor nesting materials. Regularly checking and cleaning the undercarriage, roof, and other out-of-sight spots can prevent mice from setting up camp.

Stay warm, stay mouse-free, and happy travels!
