Today we are going to learn how to keep mice out of a camper. We are going to divide this post into two sections. The first section is going to be how to keep them out of your RV, the second section is how to get rid of them if you have them. If you are in a hurry and just want the surefire way to keep mice out of a camper here it is.

The Difference Between Mice and Mouse

Mice versus Mouse is considered a “mutated plural”. For exampled “tooth” and “teeth”, “man” and “men”. “Mouse” is the singular name for one of the little rodents, wheres “mice” is the plural.

Sometimes a baby rat might be confused for a mouse. So let’s go over the differences. Neither one is worse than the other its jus that rats get much larger than a mouse.

How Mice Get In Your Camper

Any opening a mouse can find is their entryway into your camper. Even the smallest opening will allow a mouse to get inside. Common places mice enter your RV include:

  • Poorly sealed slide-outs
  • Around doors and gaps in the flooring
  • Plumbing and wiring gaps
  • Gaps where the walls meet, specifically corners
  • Electrical panels, plumbing panels

Mice and other small rodents can wreak havoc for camper owners. Mice can neat at wires, upholstery, rubber and plastic lines. These are all important components needed to run your RV efficiently and safely. In addition mice and known to spread over 30 diseases. There is a possibility you can get sick and that is the last thing you need to worry about when using your camper. These are just a few of the diseases mice and rats can spread.

  • Hantavirus
  • Bubonic Plague
  • Salmonellosis
  • Rat-Bite Fever

You can learn more about the disease mice and rats, directly and indirectly, spread on the CDC website.

It’s easy to tell if you have a mouse infestation. Here are some telltale signs:

  • Chewed food packages on counters and cabinets or any other food storage location
  • You may find rodent nests
  • Holes on your RV mattress or other upholstery and furniture
  • Mouse dropping along the walls, drawers, and cabinets.

How To Keep Mice Out Of A Camper

One of the best ways to not have mice in your RV is to prevent them from coming into your camper. Preventing them from entering your camper eliminates any mess mice will make saving you money on expensive repairs.

Campers generally have lots of small entry points that a mouse can use to get inside your RV. Finding and blocking those entry points if the first step to keeping the little critters out.

  • Get under your camper and loot for gaps or holes. Even the smallest opening is big enough for a mouse to get through.
  • One good way to find gaps and holes is for someone to shine a flashlight underneath the camper while you look inside for signs of light shining through. You can also try this during a sunny day as well. I find the flashlight method works better.
  • Check closets, cabinets, and drawers for any sign of light coming through.
  • Take careful notice around plumbing and where wiring enters the camper.
  • Check slide-out seals and inside storage areas.
  • Check access panels and your bathroom.

Once you have identified all the holes and gaps its time to seal them. Expanding foam or silicone caulk works the best.

We recommend Great Stuff Expanding Foam and Gorilla Clear Silicone Caulk. Both are available on Amazon via the link provided.

Clean Your Camper To Reduce Disease or Health Risks

If after a week or so your traps are no longer catching mice it’s safe to assume you no longer have a rodent infestation. Now it’s time to thoroughly clean your camper. Here are some tips for thorough cleaning:

  • Air out your camper for 30-45 minutes
  • Use latex gloves so no potential pathogens get on your skin
  • Use one part bleach to 10 parts water and apply to all dropping and urine
  • Allow to sit for 5-8 minutes and clean it up.
  • Pick up and dispose of droppings. Use a paper towel to pick up the dropping and then place it in a sealed trash bag.
  • Do the same with rodent nests, but this time double-bag the sealed trash bag.
  • Disinfect all countertops, floors, drawers, and cupboards. Pretty much any hard surface where there was evidence of droppings or urine.
  • Steam-clean carpets and upholstery
  • Wash all bedding in hot water.

How To Use Peppermint Oil To Keep Mice Out Of A Camper

I have to admit I wasn’t familiar with using peppermint oil to deter rodents until doing my research for this article. I came across the Mountain Modern Life blog and their post on keeping mice out of a camper. Eric and Katie’s secret to keeping mice out of their RV is peppermint essential oil. This was after they tried other natural methods without success such using Irish Spring soap bars, and Bounce softener sheets.

The method that worked for them was using 100% Peppermint Oil and cotton balls. They soaked the cotton balls in the peppermint oil and strategically place the cotton balls around their camper where mice would try to come it or areas where there was evidence of mice. In some cased one cotton ball in an area was sufficient in other instances they placed two or three cotton balls.

Why Does Peppermint Oil Work To Deter Mice?

According to Eric, the reason peppermint oil works is because it has a very strong aroma that mice do not like. The aroma masks food odors and also masks the smell of predators for the mouse. A mouse that can’t smell food and feel safe is bound to go elsewhere.

You can purchase 100% percent peppermint oil on Amazon
