Continual war against mice!

I have always tried to seal every entry point that I can find on my camper - screens over furnace openings, over refrigerator grid, etc. Last year, I took off the access panel on the bath tub to see that the opening in the floor for the drain had not been sealed at the factory - big surprise! Thought I had them all sealed last year, but still caught mice inside in traps. Today while winterizing, I discovered that the openings where the vent stacks for the black & gray water tanks go through the floor were not sealed either. I was able to slide a can of Great Stuff foam between the black water tank and the floor to spray the opening. I was able to reach the other one through the access hole on the tub, although it was difficult. I also spray some Great Stuff in the bottom corners of the slideout. Well, I'll find out as I monitor the mouse traps in the camper every few days this winter. It is really irritating that the factory didn't take 5 minutes to seal these openings!

Yikes, nice find with those missed areas. I'm actually going to winterize soon and one of the things we are doing is getting all the sheets/ towels/ bedding, etc OUT so it's much less cozy in there if they DO find their way in.

We are using a product with a peppermint smell called Mouse Mix to deter mice from coming in the trailer.

Came across this product called Mouse free I sprayed it on today going to see how well it works it’s supposed to last one year if you trailer and two years if you are parked. Check it out at it had a nice peppermint smell.

Mice’s like the dark rather than the light. Covering an RV for the winter will also invite them. Sprays and little packages that prevent mice have to be replaced/respirated constintly.

We've been using cotton balls and peppermint oil in little plastic cups, placed around the inside of the trailer for years. Never have a problem. This also helps with ants. About once a month I go in and add 10 or 12 drops to each cotton ball. We also have an Attack Wave Pestrepeller in there too. I buy the 16 oz canister of peppermint oil from Piping Rock when it's on sale - around $38. Once in a while you can get it for around $33.

Mice can squeeze through 1/4" small openings, they can not climb smooth verticals. Disconnect waterhose and powercord, place the landing jacks in 5 gal. buckets they are smooth so that mice can't climb up and build a 8" - 10" tall tub around the wheels from smooth material like tin (not wood or plywood) making sure the bottom is sealed. Don't lean a broom or anything against the trailer that the mice can use as bridge. I used this method for years on the farm after trying everything imaginable, never had a critter since.

We have used peppermint oil for the past 10 yrs. No mice despite having them in garage 2ft away. Be sure you get essential oil of peppermint and not food grade peppermint. Also be sure to keep the oil off anything you do not want damaged ( floors, counters etc) and freshen it up every 5-6 weeks. Use old coffee cups or glasses as it will eat through plastic.

I have had good luck with Fresh Cab.
Most hardware stores & home centers carry it. But next season, I may try the cotton ball & peppermint oil.
I think Forest River did a thorough job on my camper with the Great Stuff foam.

We just place packages of D-con around the unit (in spaces out of reach to humans or pets), knowing that unless we build a moat around the RV that some little critter is going to make it inside. A determined mouse can gnaw his way inside the camper. Once they eat the D-con, they get thirsty and go back outside to drink and pass away. We have a bigger issue with squirrels.

A few years back when we had a 33 foot Sandpiper TT, we took it to the shore for the weekend. When we tried to fire up the stove-top we found we had no gas. Upon further inspection, the squirrels ate through the propane hoses by the propane bottles at the front hitch. They have even eaten the engine wiring on my RAM 3500. Nasty critters. They need to eat some acorns since we have six acres of them.
