Protecting Your Camper: Mouse-Proofing Tips And Tricks

how to make camper mouse proof

Mice can wreak havoc on your camper, chewing through electrical wiring, leaving droppings, and causing damage that can be costly to fix. To keep your camper mouse-proof, it's important to take preventative measures and actively trap or kill mice. Here are some tips to keep those pesky rodents at bay:

- Remove all food from your camper and store it in sealed containers. Mice have a strong sense of smell and can sniff out food left in your camper.

- Keep your camper clean and clutter-free. Crumbs, spills, and leftover food will attract mice and other pests.

- Seal any holes or openings in your camper. Mice can squeeze through tiny spaces, so fill gaps with sealants, metal wool, or spray foam.

- Use natural fragrances like peppermint oil, black coffee powder, or garlic to deter mice.

- Set humane traps to catch and release mice, or use traditional wire traps with peanut butter or cheese as bait.

- Park your camper on a hard, paved surface. Grassy or unpaved areas are more prone to rodent activity.

- Install LED lights under your camper. Mice are nocturnal and prefer to travel in the dark, so lighting up the underside will deter them.

Seal entryways

Sealing entryways is a crucial step in mouse-proofing your camper. Mice can squeeze through incredibly small gaps, so it's important to be thorough when sealing potential entry points. Here are some detailed tips to help you seal entryways effectively:

  • Inspect your camper for any holes or gaps, especially around wiring, plumbing, corners, edges, closets, and drawers, and seals. Pay close attention to the undercarriage, floor, walls, and ceiling.
  • Seal exterior cracks and holes using appropriate materials such as spray foam, silicone caulking, or siliconized acrylic latex.
  • For larger holes, use a professional mesh or screen to cover the opening. This will prevent mice from entering while still allowing airflow and ventilation.
  • Place steel wool or copper wool inside the openings as an extra layer of protection. The sharp fibres will deter mice from chewing through.
  • For holes that cannot be completely sealed, use a high-quality RV cover or a sturdy tarp. While mice can chew through fabric, this creates an additional barrier and makes it more difficult for them to access your camper.
  • Seal the opening between the door and the base using a high-quality door sweep. Mice can enter through very small gaps, so ensure this area is well-sealed.
  • If your camper has an "outside access door" for the furnace and fridge, ensure this area is also sealed or covered.
  • Pay attention to the roof of your camper, especially if it's parked under a tree. Mice can drop down from above, so ensure all openings in the roof are properly closed off.
  • If your camper has air conditioning vents or hookup outlets, seal them when not in use. These can provide easy access for mice.
  • Use a bright light or natural daylight to identify any gaps or holes. Shine the light from inside the camper to see if any light escapes through openings. Repeat this test as needed until all visible openings are sealed.
  • If possible, enlist a friend to help. Have them shine a flashlight on the camper's exterior while you inspect the interior for light coming through.
  • For sealing materials, consider using products that stretch and adjust to temperature changes, such as siliconized acrylic latex or polyurethane sealants.

Remove food sources

Mice are always on the lookout for food, so removing food sources is a crucial step in making your camper mouse-proof. Here are some detailed tips to help you achieve this:

Remove All Food Items:

Mice have a strong sense of smell, so it's important to remove all food items from your camper, especially before storing it for an extended period. This includes items such as sugar, flour, dried fruits, nuts, granola bars, trail mix, and uncooked pasta. Even pet food should be sealed and stored securely. Remember, mice can chew through plastic containers, so only canned goods can be safely kept inside the camper.

Secure Food Storage:

When using your camper, ensure that all food items are stored in sealed metal containers. Avoid keeping food in cardboard boxes or plastic bags, as mice can easily chew through them. Keep your pantry and cabinet doors firmly shut at all times, and consider adding locks for extra security.

Cleanliness is Key:

Maintain a high level of cleanliness in your camper to avoid attracting mice. Wipe down all surfaces, including kitchen counters, floors, drawers, and cabinets. Pay special attention to areas where food is prepared and consumed. Sweep or vacuum regularly to remove crumbs and spills. If you have children, inspect their areas for any leftover food.

Be Vigilant with Trash Management:

Always dispose of trash in sealed plastic bins and place them in a designated location away from your camper. Clean trash cans regularly to eliminate any food residue or smells that may attract mice.

Deep Clean Before Storage:

Before storing your camper for long periods, perform a deep clean. Remove all food items, clean all surfaces, and wipe down cabinets and drawers. Take out any items that could retain food odours, such as toilet paper, paper towels, and newspapers.

Avoid Scented Items:

Mice are attracted to certain scents, so avoid storing pleasantly scented items like soaps or cough drops in your camper. Opt for unscented products, and if using scented items, ensure they are stored in sealed containers.

Don't Forget Pet Food:

If you have pets, don't leave their food out in the open. Store it in sealed containers, and avoid spilling or leaving crumbs in their feeding area.

Remember, removing food sources is just one aspect of mouse-proofing your camper. Combining it with other strategies, such as sealing entry points and using deterrents, will help create a more effective defence against these unwanted guests.

Clean the camper

Keeping your camper clean is one of the most important steps to preventing mice infestations. Mice are attracted to messy campers, so it's vital to perform a thorough cleaning before storing your RV away. This includes removing all food from cupboards, refrigerators, and pantries, as even the smallest crumbs or leftover oils can attract mice. Clean all surfaces in the kitchen, floors, drawers, cabinets, and under the cushions. Make sure there are no spills anywhere in the RV, and pay special attention to food preparation and consumption areas.

After cleaning, it's important to remove items such as toilet paper, paper towels, newspapers, and clothes, as mice will use these to make nests. If your camper has a "basement" storage area, keep it clean and clutter-free. Ideally, you should clean the RV every day and put the trash in sealed plastic bins in a designated location. When storing the camper for long periods, perform a deep clean.

Additionally, it's important to remove all food items from the camper when it's in storage. Mice can chew through plastic bins and Tupperware compartments, so only canned items should be kept inside. Always keep the pantry doors and cabinets firmly shut, and consider using locks if necessary.

By maintaining a clean and tidy camper, you can significantly reduce the risk of a mouse infestation.

Use deterrents

To deter mice from entering your camper, you can use scents that they dislike. Mice have a strong sense of smell, so it's a good idea to use this against them. Some scents that mice tend to avoid include:

  • Peppermint oil
  • Spearmint oil
  • Cayenne pepper
  • Mothballs
  • Cinnamon
  • Vinegar
  • Tea bags (peppermint is best)

You can try spraying or placing these scents around your camper, especially near entrances. For example, you can place peppermint-soaked cotton balls inside the camper or add a few drops of peppermint oil to fabric pieces and place them in selected spots.

Another option is to use dryer sheets, which can be placed all around the camper. However, keep in mind that mice may use them for nest-building, so avoid placing them on the floor.

Some other deterrents that have been suggested include:

  • Irish Spring soap bars
  • Bounce laundry sheets
  • Warfarin
  • De-Con
  • Cat litter soaked with peppermint oil
  • Ultrasonic sound devices (although these may affect pets)

Set traps

Setting traps is an effective way of getting rid of mice in your camper. There are many different types of traps to choose from, depending on whether you want to catch and release the mice or just kill them. Here are some tips on how to set traps effectively:

  • Use a variety of baits such as oatmeal flakes, bacon bits, peanut butter, vanilla extract, birdseed, or even nesting materials like cotton or floss.
  • Place the traps in the right locations, such as behind boxes and under equipment, as mice tend to travel through shadowy spots.
  • Pre-baiting traps can be an effective technique. Place the traps with the baits without setting them for 2-3 days, then set them and check every 24 hours. If the mice aren't showing interest, change the location.
  • Plastic snap traps or box traps are simple to set and reset, and can also be disinfected and stored for future use.
  • Glue traps are effective and easy to set up, but they are considered inhumane as the trapped mice often die a slow death from starvation.
  • Spring traps are relatively more humane and are also old-fashioned. They are designed to instantly kill the mouse by breaking its neck.
  • Always wear gloves when collecting or emptying traps to avoid any potential health risks.

While setting traps can be an effective way to get rid of mice, it is important to combine it with other preventative measures such as keeping your camper clean, sealing entry points, and removing food sources to create a comprehensive mouse-proof strategy.
