A squeaky sound from inside your camper isn't always an ungreased part – sometimes, it can even be a mouse! Here's how you can mouse-proof a camper!

The truth is that RVs are virtually as popular among mice as they are among humans. These tiny creatures are continually on the lookout for a safe place to hide from predators, have babies, and perhaps nibble on a few crumbs from the floor. Many RV owners look for ways to mouse-proof their camper, but most don't know how to go about it. It's always a good idea to know how to mouse-proof a camper.

Fortunately, there are many ways to get ahead of these four-legged, whiskered critters. From searching entry points, removing food, and cleaning thoroughly to installing LED lights and traps, covering the RV, and using mouse deterrents, we have listed various tips to mouse-proof a camper.  

Mice may completely demolish a camper by chewing through practically anything, including rubber lines, plastic, and wiring, causing costly and catastrophic damage. Preventative techniques to active trapping/killing procedures are all available. Although one strategy may be beneficial, it is usually advisable to employ a variety of techniques to achieve the best outcomes.

As RV enthusiasts, we've spent a lot of time trying to rid our campers of these pesky little critters. We've listed the most successful techniques below.



How to Mouse-Proof a Camper

The squeaky sound is what every RV owner despises the most. Having a mouse on the camper is the second worst thing that an RV owner can find – the first being water damage.

Mice have the potential to wreak havoc in your RV, and no one wants them living in their walls or cabinets. They can also nibble on the electrical wires and leave spills all over the floor. While you could always hire an exterminator, there are a number of alternatives you might want to try first.

A quick fact: mice create approximately 75 mouse droppings per day (that's revolting!). And that's just the beginning of the havoc they've wreaked.

So, figuring out how to keep mice out of your camper would be a good idea. You will have to take a couple of quick steps to keep your new furry little friends from taking up permanent residence.

If you enjoy RVing as much as we do, chances are you'll want to tell everyone about your experiences. Maybe not everyone, though. In the world of RV camping, unwelcome rats and mice can be difficult to defeat. A mobile home can be an appealing spot for a mouse to set up camp due to a fully-stocked onboard kitchen in the RV, unlike in an automobile. This is especially true if you leave your camper full of food while it's in storage so it'll be ready for the next trip.

Keeping rodents out of a camper can be an ongoing effort. Since they can fit through a hole the size of a dime, imperceptible holes and cracks in the exterior of your camper can serve as an entrance for these rodents.

Mice and other scavenging animals become accustomed to camping places where people frequently leave food remnants. Because they have near-constant easy access to food, they establish their houses in these regions.

When camping, the greatest defense against mice is to plan ahead for their arrival and take preventative measures to keep them out of your place. We'll go over all of the actions you'll need to do to keep mice out of your RV - or evict them if they've already moved in without your permission.

Search for Entry Points

The first step in keeping mice out of your camper is determining how they entered in the first place. This stage will take some time and effort, but it will pay off in the end.

Crawl beneath your camper and look for any gaps that mice could use to get in. Pay special attention to the points where wiring and pipes are installed.

After that, take a look at the outside of your camper. Are there any gaps around the door or windows? Do your plumbing or electrical panels have any entry points? If you have an RV, examine under the hood for any openings that could serve as mouse entryways.

Finally, go inside and have a look around your camper. It's best to do this on a sunny day when light shining through holes that shouldn't be there is simpler to see. Check for any entrance points in your camper's storage room.

Check the backs of cabinets and drawers, as well. A point of entry could be hidden behind a row of canned goods at any time.

Remove Food from a Vacant RV

Getting rid of any enticing morsels that can draw mice in is one of the most effective ways to keep them out. Mice have an excellent sense of smell, and they can detect any food left in your RV, including dry foods with almost no odor!

So, if you're going to leave your RV vacant for an extended period of time, make sure you empty all of your food storage. This is an excellent habit to develop in any case because you don't want food to spoil or become stale while you're on the road.

Also, make sure that the entrance door and cabinets are tightly shut to prevent invaders from getting in. If you want to be particularly safe, consider adding locks.

Keep it Clean

Another fantastic way to keep a camper mouse-free is to keep it clean by regularly removing waste. Flies, mice, and other pests may be drawn to spilled food, crumbs, and other food remnants.

Regularly cleaning and sweeping your RV is a good practice regardless of pests, but if you want to ensure a mouse-proof camper, this is a good way to start.

Do a thorough wipe down and cleaning of the work surfaces and floors after each RV trip. This will also assist you in detecting other issues, such as water damage or mold, that you should be aware of.

During this period, make sure your camper has sufficient airflow so you can get rid of any remaining food odors. If the mice aren't able to detect any food, they are less likely to attack your RV.

Clean Thoroughly After a Camping Excursion

Food products should not be kept inside your camper if it is parked for an extended period of time. This applies to condiments as well as non-perishable foods. Mice can (and will!) eat their way into a plastic bin to get to the food, even if you wrap it properly.

Aside from canned products, there are no foods that should be kept in your camper permanently. When you're done for the season, clean everything out.

Similarly, after each camping trip, make sure you wipe up any sticky spots, spills, and crumbs in your camper, including the refrigerator and microwave. You'll need to do this frequently if you live in your camper full-time.

Consider making a cleaning routine to help you stay on top of things. Mice are excellent scavengers, gladly filling their tummies with crumbs left on sofas and counters.

Close Gaps

Mice may be attracted to the safety that your RV provides even if you remove all of your food and leave it spotless. After all, it's still a sheltered, secure, and predator-free environment. They'll try to get in any way they can, so make sure you close all the doors and windows you can think of.

Mice can get in through small spaces, such as hookup outlets and air conditioner vents, so always keep everything shut tightly. Mice can also drop down from above if your RV is parked under a tree or near a rooftop.

All vents and apertures should be covered. Steel wool can be placed within all of the apertures for an extra layer of protection. Placing a few mothballs can also make it smell bad and add another layer of protection.

Cover Your RV

Consider employing an RV cover as a final layer of defense. These will assist you in your quest to learn how to mouse-proof a camper while also protecting it from debris, dust, pests, and UV damage.

Although mice can eat through cloth, a cover will provide an extra layer of protection, which should deter them. The more difficult you make it, and the less desirable your RV becomes as a food source or a hiding place, the better.

Install LED Lights

Playing on a mouse's innate tendencies is another technique to keep them out. These little creatures are prey animals who prefer to stay out of the open as much as possible. They are likewise nocturnal and prefer to travel at night.

Installing LED lights on the outside of your RV will illuminate the surrounding area, making mice feel exposed and afraid to approach. These lights can also be installed under the vehicle, as this is where the majority of them will approach from.

Use Traps

Of course, after mice have taken up residence in your RV, you'll need to figure out how to get them out. Poisoning is not advised because it might be dangerous for pets and children. You can use a variety of mouse traps depending on whether you want to catch and release the mice or simply kill them.

Snap mouse traps are widely used and highly effective. They are inexpensive and easy to reuse. However, they can be difficult to set up and, if we're not careful, they can harm you as well!

Glue traps are effective against a wide range of pests. They're effective, simple to set up, and you won't have to deal with a trapped mouse. However, each one may only be used once, and they are deemed harsh because the majority of the trapped mice starve to death.

Using a live-catch trap to catch and release a mouse is an option. This will trap a mouse in an enclosed space, allowing you to pick it up, transport it outside, and release it safely. Although it is always conceivable that mice will return, this is one of the less successful strategies.

Consider Scented Deterrents

Mice have excellent senses of smell, and there are some odors that mice cannot stand. You can use these scents to spray or place them around your RV (especially around entrances). Here are a few scented deterrents to try:

  • Mint
  • Peppermint Mothballs Cayenne pepper
  • Dryer sheets with Cinnamon Vinegar
  • Bags of tea (peppermint is best)
  • These may have variable degrees of success, particularly if they have been sitting for a long period and have lost their power.
  • Ultrasonic Sound Generator

Finally, as part of your efforts to learn how to mouse-proof a camper, you might consider employing an ultrasonic sound device. These are small electronic gadgets that generate an ultrasonic frequency that is undetectable by humans. Mice have sensitive hearing and will try to avoid loud or disturbing sounds.

The disadvantage of this strategy is that it may also impact dogs and other pets. If your pet spends a lot of time near the RV, the noise may cause them to become distressed and angry. However, if you don't have any pets, this could be an excellent way to try!

Fill In Cracks and Crevices

After you've completed your check, use spray foam, caulk, or wire mesh to plug any probable entryways you found. This includes any holes you detect in the dumping station compartment or the plumbing and electrical access panels, gaps in the floor, gaps in your camper's pull-out or pop-out sections, plumbing cracks, and cracks around doors.

Assess the Camper

Crumbs don't only collect in the obvious locations, especially if you're camping with kids. If your camper includes a pull-out sofa, make sure to check all of the nooks and crannies, including underneath it.

The same goes for all of your camper's cushioned chairs. All cushions should be removed and cleaned, and all surfaces should be swept and vacuumed.

If you have small children, getting down on your hands and knees to look for places where they may have left food is a good idea. After you've completed all of these steps, your camper is ready to be stored.

Park on Pavement for Storage

If at all possible, keep your camper away from forested or grassy regions where mice are likely to congregate. It's best to park your camper on a hard, paved surface with a cemented buffer between it and the grass and trees.

It's also crucial to keep an eye on your camper while it's in storage. You'll be able to act quickly if you uncover any evidence of rodents.

Use a Mouse Repellent

To keep the vermin at bay, many campers use homemade mouse repellents. One tried-and-true way is to place cotton balls soaked in peppermint oil in the openings surrounding the camper and at likely access sites.

Mice despise strong fragrances, and the odors drive them away. It's also worth remembering that cats are excellent at keeping mice out of a camper.

Rodent repellents, such as Fresh Cab and wall plug-in repellents that emit ultrasonic sounds, are also popular among campers.
