Re: Mice vs. RV
You are right, the ultimate solution is to find all of the openings and seal them.
But, they can get through such a small opening. They can be tough to find. Took me several years to seal up an older house I once owned.
May have to spend a lot of time going over every inch of the underside.
If you think they are coming in through the dash area, you may have to look, on the outside, at any little opening on the fire wall and plug it or make the opening too small for them to get through.
Small pieces of cut out aluminum sheet or tin can steel, glued or pop riveted in place around shafts and wire bundles. Steel wool pushed into the hole. Silicone caulk in some places.
Could hang some bags of moth balls under the hood. They do repel mice, but not sure how well in such an open well vented area. Remember to remove them later.
They must be coming out side to feed if you do not leave any food inside. (And I'm sure you don't) Trap them outside?
You could make up four of the 5 gal water filled bucket, wire, and pop can traps and leave one near each tire with peanut butter on the can for bait. And a ramp for them to get up to the top. At least until freeze up.
As long as dogs and cats can access the buckets, do not use anti freeze. (I am sure you knew that) But if you could make a chicken wire or welded wire fence cage around them, well tied down, could then use with anti freeze in freezing weather. I have used those with good results in barns, milk houses, and sheds, but never in the open.
I have also made them from 1 gal ice cream pails, stiff wire, and only one can on the wire. 3" of water in the bottom.
Maybe put 2 or 3 inside the RV? No smell that way, just clean out the dead ones every couple of weeks.
1 gal ice cream pails need to be cleaned all the time. Mice climb up on the floating bodies and can jump to the rim of the pail then climb out.
I wish you luck!
