How do you keep mice out of MH

I took a 10 foot by 48 inch piece of sheet metal and cut four 12 inch wide pieces out of it to make a rectangular boxes to put around the wheels. Used four 90 degree bends in it to form a rectangle of the proper sizes. Around the front suspension I had to trim it down from 12 inches a couple places for a fit. The extra length gives me lots of overlap to of the two ends to clamp with a small clamp.

For the jacks, I just use 12 inch metal flashing off a roll to form a circle around each jack. Those are tricky to get a seal at the bottom if you are using boards under the jacks - unless you plan ahead.

For those who say seal all the holes going inside the rig, what about those nice rubber hoses on top the gas tank? And those plastic air lines for the air bag suspension (which I have on the rear)?

I keep the TT plugged in to shore power all the time. I have several ultrasonic pest repellant plug ins in the camper(the ones that plug into an electric outlet). Also have a cat that likes to hang out under the TT when he is outside.

Although this was written for structures it easily adaptable RV. The principles are the same.

I've had good luck with mothballs keeping rodents out of a boat and TT.

Of course, one requirement is to not keep food in the trailer.

The product that Midnite mentioned is Cab Fresh.. I bought it at Ace hardware.. Developed to keep mice out of farm equipment..

If you have pets and or allergies stay away from off the shelf sprays.

Peppermint Oil does work. Has to be 100% PURE oil. Pricey but works.
IMHO it's more prudent to find out HOW they are getting in.

What I found was that when MH's are built there are a lot of exposed over sized holes where they run wires pipe etc. They are small and hard to see but they are big enough for mice to squeeze thru.

Go out at night and turn the lights on in your MH and crawl underneath. You will be 'shocked' at how many places you will see light seeping thru. Use the insulating spray called 'Stuff' to seal the openings.

two things mice don,t like peppermint oil. and a product called cab clean .farmers use this in the combine and tractor cabs. you can get both off ebay , I use them in two rv,s and three boats no mice. I never heard of a spray. oon google you could check mice control.
