Spray foam all the entry points. Crawl underneath and inspect ever inch of it.
When we shrink wrap and store pontoon boats we put a few dryer sheets on board. I also place trays of mouse bait underneath. If I use traps, I bait with peanut butter.
I do have dryer sheets in the basement which is where I have caught the most mice.
I could use bait but I am afraid they would die somewhere on the trailer.
Occasionally I see a large rat snake in the barn, but I think the mice population is overwhelming them.
