Mouse proofing an RV.... ideas?

[Tapp8277]

I'm pretty sure I read about this on a past thread, but couldn't seem to find it with a search.  So, this past weekend i figured I'd open up the 'ol tent trailer to see how she wintered....... mouse poop everywhere! I know the little critters can basically get into anything, but is there any deterrents you guys have found effective? Appreciate any advice and/or suggestions.

Put the trailer in a shop or garage.  Turn off all the lights, in the building and turn on all the lights in the trailer.

  Get a couple of cans of expanding foam, and a bunch of steel wool, and plug anything that you can see light.  They also like frig vents. put metal screening on any vent(s). 

I did battle for a month with a little hitch hiker for a month this fall, I feel your pain.

A open jar of ammonia inside camper
Just pull it out and air out a couple days before using it

I've heard something about them hating steel wool.

Ammonia huh? That's definitely worth a try

After sealing up everything you can put a few bags of Fresh Cab in places...

We used dryer sheets in our trailer and it seemed to work pretty well

Irish Spring soap shavings in the nooks and crannies.

Any of the above works, I also had to skirt the tires and jacks with sheetmetal so they couldnt even attempt an entrance. PIA but after waging a war all winter all efforts were needed. Really sucks when you turn on the AC after sitting all winter and it blows out handfull of chewed up insulating foam.

My neighbor has Tomcat bait boxes outside on the ground on all four corners of his trailer.  He says it works.

You need a mouse management plan. I had packrats and mice every where but after two years of live traps and poison bait traps/snap traps I rarely now get one. No home should go without those little black containers with poison in them. If everyone would use them, their problem wouldn't become your problem.

As stated above, those Tomcat bait boxes work and are relatively pet safe.

Sooooo...... it looks like all-out war is my approach! Traps, perimeter defense, interior reinforcements, plus with Irish Spring and fabric softeners I should have a very nice smelling rig 

I appreciate the ideas so far!

A bottle of any peppermint essential oil this size in a standard spray bottle filled with water, spray all over area you don’t want mice in.👍

I use it on our cars wheel wells, trunks, engine compartments, smells good and doesn’t hurt anything.

Can be found at rite aid, or stores that sell vitamins, food Co-ops etc.

If none of this works, I highly suggest a GAU-8. At least it will be fun to watch.

All suggestions work but you must stay on it .
There is always that one rodent that won't play by the rules.
Squirrels and chipmunk they chew up more than mice .
