Mice may be small and cute, but they can cause big damage and an ugly mess.

Jennifer and I have heard horror stories through the years of how mice chewed through wires, insulation, and walls. Not to mention the nests they build that can clog vents and wreak havoc on your appliances and engine.

Even a dead mouse can cause a stink-up! Anyone whose returned to their RV after storing it for winter months only to be confronted with a terrible smell knows what I'm talking about.

So, whether you have a rodent problem or want to avoid one in the first place, here are some tried and true tips to keep them away from your RV.

5 Preventative Measures to Keep Mice Out of Camper

The best way to prevent a mouse infestation is to keep them from getting into your RV at all. That means blocking off any potential entry points a mouse might use to infiltrate your rig.

There are several methods to do this. Chances are you'll need to use more than one depending on the type of holes and entry points you're dealing with.

1. KNOW HOW MICE GET IN

You'll see in the next section that the first step to preventing mice from getting into your RV is to search for entry points. But that means you need to know what to look for!

When searching, remember that mice have collapsible rib cages. Why is that important? Because that means if their head can fit into a hole, so can the rest of their body.

A good rule of thumb: if a pencil can fit, a mouse can fit.

So, when looking for potential entry points, you have to look for even the smallest holes and cracks that a flexible mouse can take advantage of.

2. SCOUR THE EXTERIOR OF YOUR RV FOR POSSIBLE ENTRY POINTS

Now that you know what to look for, the first step is to scour the exterior of your RV for any small cracks or small openings.

I recommend taking a flashlight and brightly colored tape with you so you can find and mark every possible entry point. Then you can determine what materials you need to cover or fill the openings.
