Mice/rodent proofing a camper

Because you used peppermint oil once with no mice does not mean it works...
In fact, using it for two years doesn't mean it works...

For what it's worth, the peppermint oil previously mentioned is truly magic when it comes to mice. I've actually written a post on my site that talks a little deeper and I'd be glad to answer more questions in regards to this.

Mice, rats, and squirrels will get into any enclosed structure if there is food present, the residue from food, or it makes a suitable shelter. The best defense is to make sure there are no ways to get in (seal all the holes), take all food out, and clean up the food prep areas. Traps and bait should be placed outside the trailer, you don't want a rat crawling into a wall and decaying.

One of the best deterrents is a cat. Even letting a cat live close to the RV or inside awhile so the cat's scent remains, will notify the rodents that a predator is present or has been in the area.

Best defense is plugging the entry holes. The year I had the most problems I figured out it was because I left it plugged in and they used the cord as a highway through the cords entry port. Now I make sure the hole where the cord enters the trailer is plugged anytime the cord is in use.

I have found it is the luck of the draw. Some years no mice, some years they hold their prom in my sink.

I suspect the dryer sheets I used to repel them this year; made fine winter nesting.

If you put bait inside the trailer you will attract the mice inside. I would put it outside of the trailer. Also get expanding foam and plug up anywhere there is even the tiniest opening under the trailer. ie places where pipes or wires enter the trailer.

I'm still trying to picture how a mouse gains access to an RV. As far as I know they can't really jump and assuming there are no trees/shrubs/etc. next to the coach, the only way up would be via the tires or the tongue jack (assuming a TT). I can't imagine any way a mouse could climb the smooth steel sides of the tongue jack, so that only leaves the tires.

So, if the mouse climbs a tire, now what? Can't get to the frame. Maybe could make it to the axle, but then where from there? I understand that they do get in, I just can't quite see how?!?!

Yep. Our first winter with our tt, I added enough dryer sheets to keep a heard of mice warm all winter.

Our tt also had a fabric underbelly and squirrels chewed 11 holes through it and had enough nuts stored under there to keep them fat and happy for many yrs.
