Nobody wants mice inside the RV as they damage things, eat our food, and are vectors of a vast array of diseases.

We have covered 10 ways as how you can make sure that mice stay out of the camper.

But, remember this will be a long battle against the intrusion of mice, and there is no long-term solution except regular checks and preparation.

Let us know them one by one!

Most of the time mice enter a camper in winters because they need shelter and food. An RV provides both things, especially if the camper is not clean and well protected.

You can try the following tips and preventive measures to avoid mice inside the RV.

1. Inspect all possible entry points

If your checklist has cleaning mentioned on it then make sure to add another point to look for possible entry points for mice.

Mice can enter the camper through holes, cracks, seams along with the slide-out, gaps besides sever, water and electrical system, doors, and windows.

The door and windows can be kept closed but what about those holes from where mice can enter the RV easily.

First crawl under the RV to look for holes, gaps, and cracks. Areas such as pipes and electrical lines are possible entry points. The exterior side of the RV is also important as gaps around the camper door and windows are large enough.

An interior inspection will make a difference as it is easy to find holes inside than from outside. Do this on a sunny day and keep the lights inside open.

Go through a thorough inspection and look for the entry points. Remember mice can enter through a hole smaller than a dime or spaces as small as ¼ of an inch. You should not leave any holes as it is good for insulation purposes too.

2. Seal all cracks and holes

After inspection, the next step is to close all the entry points. You can use spray foam, wire mesh, and caulk to name a few things to seal the gaps, holes, and cracks.

Possible areas are gaps around plumbing and electrical lines, cracks around doors and windows, holes and cracks in the floor, and gaps around access panels of electrical, water lines, and dumping station compartments.

3. Always keep your camper clean

Cleaning the camper is a good habit as it keeps the camper disease and pest-free.

Look around areas such as tabletop, cabinets, and drawers. The kitchen and area near the dinette should be cleaned nicely.

If you have children then look in places such as under the couch, beds, and tables. Left-out food attracts mice and other pests easily.

Clean the microwave and refrigerator too as the smell of leftover food can attract a mice.

4. Avoid keeping food in RV after a trip

Both, Perishable and non-perishable food should be kept out of the camper if you are not using it for more than a week.

Keeping food inside plastic bags cannot do the job as rodents can easily get access to it by chewing the plastic.

Canned food can be left as they cannot chew metal.

5. Store the RV on the concrete surface

Always store your RV on a hard surface such as concrete. Most of the time we tend to store it in a place where you find a space such as on grass and near trees and bushes.

In an ideal condition, you can find mice inside your camper because they live in these places and can get access.

Storing it in a concrete place makes sure that there are no holes and cracks on the ground where these rodents make a home.

6. Keep windows and doors closed

Keeping the doors and windows closed all the time is the safest way to prohibit rodent entry inside a camper. It also makes sure that animals like reptiles, bugs, insects stay away from the camper.

These animals are found in cold, hot, humid, and dry places so keeping the doors and windows closed is the best solution for the problem.

7. Use rat poison

Rat poison works well for them but people do not use them as sometimes mice eat them, die, and are difficult to find. The smell of a dead mouse is not what people like and it stays for long after removing the dead mice.

It is good when you are not going to use it for long. You can keep it inside a suitable place such as under the table. If a mice gets inside the camper then it will die. But, make sure to check in few days to remove the dead mice.

If you have children and pets then avoid it completely as it is dangerous for them.

8. Use mousetrap

A mousetrap is a good option instead of a rat poison. It keeps the mouse alive in some cases where you can leave it far away from your home on wheels.

There are different types of mouse traps available in the market select the one which suits your need.

9. Mouse repellent

Home-made repellent is a good option to keep mice away. People who have earlier use these repellents swear that it helped them.

Cotton balls soaked in peppermint oil are one of those homemade mice repellent. Rodents do not like strong smells.

You can also keep dryer sheets, mothballs, and Irish spring soap as well at the possible entry points.

Rats fear cats, keeping a cat will always do its job. Wall plug-in repellent also works as they produce ultrasonic noise which pests and insects hate.

10. Use RV cover

Yes, an RV cover can also help you out in preventing mice from entering your RV.

RV cover adds an extra layer of protection from rain and snow which corrodes the exterior of the RV weak and a possible entry point for the mouse.

It also keeps the smell of food from leaking out from the camper. A durable and good-quality RV cover will do the job.
