If you’re looking for how to mouse-proof a camper then you’ve come to the right place. Rodents such as rats and mice in RV and other similar vehicles are quite a common problem that needs to be dealt with quickly and decisively. How does one go about that, however? Here are our RV pest control tips on how to rodent-proof your camper.

How can mice or rats enter your RV?

You may think that your camper is well-sealed but you might be underestimating these rodents’ ability to fit into small places. Here are several of the most common entry points rats and mice usually find in RVs and campers:

  • Cracks under or around doors
  • Floor gaps
  • Slide outs that are not sealed well enough
  • Plumbing or wiring gaps, as well as plumbing and electrical access panels
  • Cracks and corners in-between the wall panel pieces

Why do you need to keep rodents away from your camper?

The many significant problems rats, mice, and other rodents can bring to your RV should be rather apparent but here’s a quick list to keep in mind in case you’re still wondering whether you should bother rodent-proof your camper:

  • Rodents such as mice and rats are more than capable enough to cause physical damage to your vehicle.
  • Rodents can easily spread a large number of different and dangerous diseases that you don’t want in your living space.
  • Getting rid of a huge rodent infestation is costly and messy so it’s best to deal with it while it’s still small or to prevent it altogether.

As you can see, keeping your RV or camper rodent-free is as important as it is for your home and property.

So, let’s look into some tips and trick you might want to employ.

Tips for keeping mice, rats and other rodents out of your camper

So, how to keep mice out of RV, as well as rats, squirrels, and other similar rodents? There are multiple vital steps you should take and skipping even one of them can easily lead to a fast and unrelenting rodent infestation. So, here are our suggestions:

  • First, carefully inspect the vehicle for an already existing infestation, even if it’s still just a minor one in the form of just one rodent couple. Many of the tips below will be woefully ineffective if there’s even a single pregnant rat already present in the floor of your RV.
  • Carefully seal up any hole, opening or another place a small mouse can crawl through. This is where a lot of people make the mistake of underestimating just how small a mouse can be and in just how small of a hole it can fit. Any hole bigger than a dime – about a quarter of an inch – can be big enough for a small mouse to fit through. Yes, you read that right.
  • The easiest way to seal up your RV is to get beneath it and look for gaps in the undercarriage. It’s best to do this outdoors and in midday, as you’ll be able to easily check if you can see the daylight from anywhere.
  • Pay extra attention to the plumbing and wiring of the vehicle. Wrap each water and sewage pipe with a heavy aluminum foil. Extend the foil several inches past the pipe’s entrance and flare it out around the pipe. Also, examine the plastic cover of the power access lines seal them tight if need be.
  • After you’ve secured the undercarriage, wiring, and plumbing of the vehicle, look at the sides of the RV – the doors, windows, and other openings that might be big enough for a mouse or a rat to fit through.
  • Use a potent rat and mouse repellent. It could be a strong natural repellent such as peppermint or spearmint oil, or it can be a commercial, industrial rodent repellent. Be careful if you’re going to be using the vehicle in the meantime, as a lot of these products can be quite potent and smelly – choose and use them wisely. Also, keep in mind that even a strong repellent may not be enough against a determined rat colony so you can’t rely solely on that.
  • Do routine checks of the vehicle every month or every other week. This may sound bothersome but it really isn’t that big of a deal once you make it a habit. Catching a rodent nest in its earlier stages can make a world of difference compared to having to deal with an overblown infestation.

A second and equally important question is how to keep mice out of RV in winter months. Winterizing your RV or camper is a very important step, both against rodents, as well as different pests such as moths or other insects. So, here’s a quick list of winterizing tips that you’d also do well to follow:

  • Remove all unnecessary items from the camper. Items such as blankets and other fabrics, plastic bags and boxes, camping supplies, cardboard boxes, and so on.
  • Double-check all the sealing you’ve done before and re-seal everything.
  • Place an extra dose of more powerful rodent repellent in the vehicle. This shouldn’t be much of a problem now since you won’t be using the RV anyway.
  • Once spring arrives, inspect your camper very carefully for any sign of mice, rats, or other rodents, as well as insect pests while you’re at it.

In conclusion

When looking for how to keep mice out of the camper, it’s important to be diligent and careful. Skipping even a single step or putting it off with even a week or two can mean the difference between dealing with a couple of mice and dealing with a couple of dozen mice.
