One of the top things that RV owners dread. Mice…

Despite RVers fears of the notorious poo-pyramid, tire blowouts, or becoming stuck— these furry and rather frustrating things can even be as bad as those two words RVers NEVER want to hear… Need a clue? It rhymes with “Shwater Shamage”…

It’s not just their droppings or glimpse of a scurry across the floor that makes RVers shiver. As a matter of fact, it’s their immense destructiveness while also posing a serious health risk to you and your traveling family.

While mice can wreak havoc in campers, there’s preventative measures and different options you can use to help keep your RV free and clear of these pesky rodents.

Mouse Removal & Traps


Keep in mind…

There’s different methods of ridding homes and campers of mice, but one thing worth noting, is the risk of poisoning these guys.

As if mice are the last thing you want to deal with– DEAD MICE are the VERY LAST THING you ever want to deal with– in your camper… decomposing… in a wall, crevice, or cranny that you can’t get to to properly dispose of…

With that in mind, you may choose to consider a few other options of rodent control.



Prevent mice from moving in

Obviously, preventing mice from even accessing your camper in the first place is ideal

This way you’re less likely to have to take further steps in getting rid of them and cleaning up after them– which can be even more expensive, time consuming, and aggravating.


Block them off

First, you’ll want to block every possible access point they can squeeze through.

RVs incorporate so many parts and pieces, moving mechanisms, and components capable of running from the outside in, powering and providing water to the unit. This in turn can create potential points of entry (around seals, slide-outs, wiring, and plumbing) for mice to squeeze through. 

So, grab a headlight, an old rug to lay on, and do some stretches– because we’re going under!

Look underneath the RV at the underbelly for any holes, gaps, and cracks indicating potential access points. Look around exposed plumbing and electrical cords going up into the unit. Use fill fabric or foam sealant to block off any openings where a mouse could squeeze through. Make sure to double check previous patchwork and touch up where needed.




Also, examine the cargo compartments, generator, battery compartment, and wet bay area.

Then, check the inside for holes and gaps. Look under sinks around plumbing, check the under-bed storage area, look in closets; pantry, kitchen cupboards, around the washer and dryer hookup, etc.

For motorhome owners, also check around the driver and passenger area for crevices or cracks a mouse could sneak in from. Remember, mice can get through the tiniest holes!

Above, is a storage and wet bay compartment on a Forest River fifth-wheel. From inside the wet bay, the water hose is thread through the bottom of the compartment and out to the campground water spigot. This design gives a mouse the chance to easily climb up the water hose and enter the wet bay compartment. This wouldn’t be the biggest deal if the wet bay was completely sealed-off from the rest of the RV. However, unfortunately (and quite shockingly) this wet bay does not completely close off from the cargo storage area–right next to it. In fact, there happens to be a 3/4 inch gap between the dual-compartment door and wall dividing these compartments– making the attached storage compartment easily breach-able for a mouse that has made it into the wet bay! From there, it can squeeze into the cargo where there’s loads of camping gear, warmth, and possibly further access points into the RV interior. 

Keep in mind, finding the actual point of access can be downright impossible. With so many dime-sized gaps around plumbing, poorly sealed compartments, slide-out seals, and spaces around electrical cords, mice have a good chance squeezing through somewhere to gain access.


Clean, clean & clean

Many may leave this task for spring time when they are ready to bust the RV out of storage. However, you’ll want to spend some time deep cleaning your unit BEFORE putting it in storage.

Remember, you don’t want anything in the unit that could attract mice. A place with endless crumbs, bedding, and supplies at their little rodent fingertips makes it a place they’ll NEVER want to leave!

Do a thorough deep clean:

  • Remove all food items.
  • Remove trash.
  • Wipe down cabinets, the pantry, and surfaces.
  • Remove any valuables that could be chewed up and destroyed.
  • Sweep or vacuum any leftover food crumbs (paying extra attention to under furniture, around slides, in cupboards and cabinets, and cargo areas.
  • Store linens, toiletries, electronics, or non-perishables in heavy-duty, latchable bins. Especially cutlery, paper towels, napkins, or other picnic items that could be subject to mouse droppings or chewed up and used for their new nest.

Park wisely

Unfortunately, many RVers can’t store their RVs inside a storage facility to help keep rodents away. It’s often slim pickings when it comes to parking and storing campers during the off-season. Obviously, if possible, a clean storage building significantly helps prevent mice.

Aside from indoor RV storage, select a level surface– preferably on concrete and away from a wooded area or grassy field. Clean the location of any debris and keep the grass and weeds around the parked unit cut short.

Getting Rid of Mice

Past the point where rodents have already moved in? 

Mice can move in and multiply fast. Without routinely checking your RV unit throughout winter, mice can be taking advantage of your pricey investment for WEEKS without you knowing.


Mice in RV motorhome campers


With that in mind, it’s extremely important to frequently check on your camper whether it’s sitting in storage, at a seasonal site, or parked in your yard for long periods of time.

Unfortunately, once evidence is found you must act fast! Mice can be extremely destructive, causing costly damage and posing serious health risks.


Mouse Removal & Traps

Just like repellant, there’s a variety of mouse traps and removal methods for your storage situation and/or personal preferences.

Keep in mind before considering bait stations or rat poison…

Not only can bait and poison be harmful to children and pets but can actually be more of a hassle to RV owners. As a matter of fact, bait or poison does not work immediately, causing rodents to ingest the substance and die shortly after. Between the time of eating the bait, rodents can crawl right back into their cozy location– in the RV sidewalls, motor, plumbing, or– basically somewhere impossible for humans to get the soon-to-be-corpse. Even if poison is placed outdoors around a parked unit, mice can still eat or carry the bait back inside the RV– and worse case scenario– back to the nest– leaving you with a decomposing family of mice somewhere in your RV that you can’t properly dispose of!



  • Never use poison at public or private campgrounds where other campers, people, and pets are present.
  • Block off all potential access points from in and outside the RV.
  • Keep your unit clean and remove food and trash. Store other belongings in tight-latching bins.
  • Park the RV on a clean, concrete, or gravel area that is well-kept.
  • Routinely check up on your RV unit and look for any signs of mice invasion (droppings, chew marks, nesting).
  • Use repellent to ward off pests and prevent them from taking over your camper.
  • Upon finding evidence of mice, act fast by placing removal devices and/or traps.
