13 Best Ways to Mouse Proof Your Camper Trailer

Eek! A mouse!

No one likes finding an unpleasant furry surprise, but it does happen. Now imagine that instead of spotting one of these rodents in your house, you had a mouse scampering around inside your camper trailer.

If you’re squirming right now while reading this, that’s certainly understandable. After all, mice are considered pests for a reason. They leave droppings that can irritate previous respiratory conditions (not to mention the horrible smell) as well as chew up any parts of your trailer that look appetizing. These include rubber and plastic surfaces, wires, cushions, upholstery, and yes, food, too.

Obviously, if you have a mouse problem in your trailer, be it one or even several mice, you’re going to want them out, stat. Here’s a list of handy ways to rid your camper trailer of mice and keep them from coming back.

1. Know how to determine if you have a mouse problem

How do you know you have a mouse problem? Keep your eyes out for the following signs:

  • Mice nests, which may be in your bedroom (yuck!) or those of your passengers as well as anywhere else where there’s comfortable, plush material (think couches and other bedding).
  • Weird food or small items you yourself didn’t bring in. It could be the mouse that did it!
  • Ripped-open food bags and wrappers as well as damaged containers. Unless you have a really inconsiderate passenger onboard, then it’s more than likely a mouse was the one to tear through your food like this.
  • Bedding, clothing, and mattress holes that certainly weren’t there before.
  • Mouse droppings, which are the biggest and most telltale sign of all. These aren’t always out in the open, so you might have to go looking for them. Make sure you wear gloves if you do!

2. Stop leaving your doors and windows open

Look, if a mouse wants to squeeze into your camper trailer, then they certainly will. Don’t make it easier for them by leaving your camper doors and windows wide open. Otherwise, you could be inviting unwanted passengers aboard.

3.Check your access panels and seal these

Most access panels are found in your camper’s bathroom nook, but these may be elsewhere in your vehicle as well. You will have to take them down and look in the space beyond to see if you have mice hiding out. If you see droppings, then obviously this is one of the places the mouse has lived. Use caulk or another sealant to close off the access panels.

4. Seal slide-outs as applicable

Slide-outs are more common in RVs than camper trailers, but if yours has one, be weary. All those mechanisms and narrow gaps make the perfect home for rodents. Once again, you’re going to want to reseal this space to keep it free of mice.

5. Look for gaps in the wiring and plumbing of your trailer

Grab a flashlight and inspect the wiring that powers your refrigerator, lights, air conditioner, and furnace. Are these wires in good shape? Have they been gnawed on? More importantly, if you see large spaces, then mice could get in there and damage the wiring.

Now do the same with all plumbing fixtures. If there’s too much space between the pipes, you’re going to want to call a pro and get this fixed.

6. Check all edges and corners

Your camper trailer has a lot of edges and corners, so you should get familiar with all of them. Again, you’re looking for any gaps and spaces in which a mouse can crawl through.

7. Clean out all closets, cabinets, and drawers

If none of the above have yielded you any results in getting rid of your mouse problem, then you’re going to have to resort to more extreme measures. It’s now time to gut your closets, cabinets, drawers, and any other cubbyholes within your trailer.

Fully remove anything and everything. Your flashlight will come in handy once more for sweeping dark corners. You’re looking for nests, droppings, or a mouse itself. You should also be ready to find any holes in which a mouse could have gotten into your camper, which you should then seal.

8. Inspect beneath the vehicle

With the supervision of a fellow passenger, go beneath your camper trailer to look for holes and gaps. It can be dangerous to climb beneath heavy vehicles like campers and RVs, so try to keep your time underneath there limited. Double-check everything and patch up holes as needed.

9. Keep your vehicle clean of food crumbs

Food crumbs are quite appealing to mice, as these will sustain the furry creatures. Make sure that whenever you prepare food that you wipe down all cooking surfaces when you’re done. Remove trash often and wash out bowls, cups, plates, and utensils after using them to keep your trailer free of food waste.

10. Remove all food items when leaving for the off-season

When the off-season finally arrives, do not leave a single edible item on your vehicle. Yes, this includes condiments, jams, and other foodstuffs with generous expiration dates. Get rid of everything. Mice seek protection in the winter. They’ll get in your camper and hang out, gorging themselves on the food you so kindly provided them.

11. Don’t leave your camper trailer vacant for months

On that note, be sure you get back to your trailer at least once during the off-season. You want to check on the state of all your seals as well as look for any new holes or gaps. Keep your eyes peeled for mice droppings and nests, too!

12. Set some mousetraps

If you’re sick of your mouse issue and want solutions right away, try a mousetrap. Today, there are many options on the market besides the old metal and wood versions. Some traps on Amazon even deprive the mouse of oxygen. The mess is all contained, and there’s no blood.

13. Use peppermint oil.

Of course, some people are against killing mice, and that’s perfectly fine. In that case, cover offending surfaces of your trailer with peppermint oil. This natural product smells like Christmastime, yet mice can’t stand it. If you accidentally touch or ingest some, there should be no ill effects.

If you don’t want to douse your trailer in peppermint oil, you can always opt for a natural spray, like this one for under $20 on Amazon.

Conclusion

If you think you have a mouse running around your camper trailer, you now know how to mouse-proof it so that you can focus on enjoying your trip and not fending off stinky rodents. Safe travels!
