Rodent Proofing ? Best Methods, What works, what Doesn't

A couple of years ago mice built a nest about one foot from a container of moth balls in my snowmobile. I went to snap traps that solved the problem.

I use conventional means... I store my unit in a building that has cats. never a rodent issue in 15 years. Cats always handle the vermin....and leave paw prints...

Biggest thing is plugging ANY hole they can get in. We've just been lucky so far with dryer sheets and peppermint oil.

Ours is a park model (stopped towing) and skirted so it reduces the chance they get in, but they still can. we leave traps underneath and poison too, then check in the spring.

good answers all , but you gotta crawl under the rv and plug ANY HOLE even the holes as small as a pencil. then use fresh cab and peppermint oil drops .

Mothballs.

Fresh Cab is being "reformulated" and is hard to find. Amazon lists it as "Currently Unavailable". Besides, it only lasts 3 months. If you don't get in to change it out, the repellent becomes food.

We needed to find something to replace Fresh Cab when we couldn't get it for the store. We found Sniff 'n Stop. Apparently it overpowers the rodent's sense of smell and when they can't smell predators they get nervous and go elsewhere. They claim it lasts up to a year.

I found dryer sheets all over mine when I bought it from the RV shop...no rodent telltales around

I use wood snap traps but no bait. Do not want to entice them to come in. Mice are dumb...they crawl all over everything. They will crawl over the snap traps with no bait. I have caught a lot of them.

I am a believer in using moth balls. I take the small plastic cups, punch some holes in the side and fill about half way with moth balls. I put them everywhere knock on wood have not had a problem.

Wooden snap traps.Peanut butter. Tried other stuff...these work. Buy around a dozen, put some outside, others inside. All around. Sometimes reusable. Replace peanut butter every 2-3 weeks.

I get most in the generator section. Why? Don't know. I average 3-4 a winter.
