As I am sure some have seen my posts on mice prevention and how those gimmick solutions do not work. I have always maintained that they only way to prevent mice is to seal up the trailer.So after parking my trailer where I have gotten at least one mouse every year for that last two within a month(while using PURE peppermint, dry sheets, moth balls and cab fresh), I was cleaning where my low point drain is in a plastic container in the floor. As I felt under the lip with my cleaning rag, I could feel that the plumbing came into the trailer from outside in a hole that was about 1" bigger than the plumbing.I got some mice prevent spray foam and a mirror to spray the hole sealed all around the plumbing.I checked on the trailer this past weekend and for the first time in two years, the traps are empty and I do not have a mouse yet(trailer has been there since mid October)Anyway, point is if you get mice, they are getting in from somewhere, and that somewhere isn't always visible.

I agree,yet fresh cab and oil works for me.and my boat sits in a open pole bldg.

Seems obvious to me that the first step in preventing mouse intrusion into one's camper is to seal all potential entry points. As a secondary precaution I keep a couple of Fresh Cab Rodent Repellent Packs in the camper year 'round and haven't had any issues at all. :B

You're pretty thorough SoundGuy. I am pretty certain that your probably sealed up your camper pretty good!

OP, I could not agree more. When you seal up the entry points, you stop the meeces. Even regular spray foam will do it. I've done this on 4 RVs, and it worked every time. However, one fiver's slideout systems were not really seal-able. That was a challenge. I made up magnetic removable sheet metal covers for the under-slide openings.

Two of them were purchased new. one of the first things I do when i get it home, is crawl underneath the entire trailer and fill any hole I see, no matter how big or small, with Great Stuff expanding foam. I also store with drawers and cupboards open (mice prefer to build their nests hidden, not exposed) and I go crazy with dryer sheets on the inside. Not sure if it works, or the place I store it doesn't have a mouse problem. I don't really care, because either way, they're not living in my trailer.

Friends told us that peppermint oil on cotton balls would drive mice away.

OK, so we douse 25 or so cotton balls with peppermint oil, put them in little paper bowls and hide them all over the trailer.

Came back several days later and ALL of the cotton balls were just gone.....you tell me....

Mouse trap with peanut butter worked the same night...

Problem solved.

Fresh Cab is laughable. I have a place mice get in and cannot find the entry point. I use one bag of fresh cab in the storage area...Glue trap got the mouse. This year, in the fall I tried 2 fresh cabs in the compartment. Got a mouse on the glue trap. If it make people feel wasting 12 bucks on Fresh cab go for it

I suppose you could claim that dryer sheets and such repel elephants and lions too since I've never heard of anyone having problems with either after placing dryer sheets and mothballs in their RV. :)

Exactly!

I think sealing is the only way to keep mice out of anything. You can set traps but you can never catch them all unless you seal the entry points.

I've seen folks say that all manner of things keep mice away. I once found a mouse nest made out of dryer sheets. Mothballs and all kinds of oils and extracts have never worked for me. I've never found anything that actually repels them.
