We have a camper van that seems to be a mouse magnet. Most of the time snap traps cuts the invasion short, but that doesn't seem to be sufficient now. I have crawled under the van and put steel wool a few places, but it's a mystery where they get in. Putting a device under the hood with flashing lights and ultrasonic noise has proved ineffective.

We are seeking someone with experience sealing up the undercarriage to prevent mouse entry.

I don't think there is any such thing as "mouse proofing." I trap them relentlessly in the spring starting March 1st and it works. The only defense is a good offense.

I keep 12 traps baited and checked year round. I have an Airstream, I set four under it. My first year I killed over two hundred on the property (yes I keep track, 236 to be exact). 35 in April, 11 this month. They invaded my cars at first but there has been no issues in the Airstream, cars or house in four of five years. Bruce Herron Wolf Creek

I can only second the previous comments.
While you keep searching for your preferred remedy, get those basic
wooden traps, bait them with peanut butter and place one on the inside
of each wheel, check daily.
We have a camper van, done this for years and keeps working, even and
particularly when out in the back country.
Good luck,
Peter, in Twisp.

Thanks all for your advice. Off to hardware to get more traps.
