Keeping mice out/away of racecar trailer

I don't try to repel mice, I kill them if they get in. I use these Victor hammer traps and they work great. A little peanut butter in the back of the bait well and they never miss. As soon as one gets into my garage, they smell the peanut butter and go straight for it.

I have killed dozens using these over the years in 4 different houses. Never had a miss.

I had some field mice in the attic. Put normal style traps with some peanut butter. They would get the PB out of the trigger lever without it activating. I started putting a piece of tape over the PB. Worked after that.

That hammer trap is cool. The have to stuck their head into the tunnel and that snaps the "hammer". More effective than the old style snap traps.
