Are you saying that works? What would the predator pee be? Interesting concept. Where do you put it?
Or am I just falling for a smart alick answer to all the above. I have never heard this.
Naw, it's a true answer - I just get tired of everybody ignoring me every time I mention it. I did a lot of research - including reading every dang thread about vermin on this forum - about keeping mice out since I knew we had a problem and I didn't want one in my RV.
Predator Pee is the ONLY solution I found that has no detractors. Somewhere on here are at least two more of my posts just like this, but people keep posting about dryer sheets and tin foil and traps and whatnot, so I'm a little jaded and bitter, is all. :-\
Think 30 bucks is expensive? Try paying to replace all the wiring in your motorhome's engine compartment.
There, I've said my piece.
For mice in a vehicle, this is your solution:

For the 1-1/2 years my RV sat in a mouse-infested rural yard, I had NO mouse intrusion, while our cars certainly did.
It lasts WAY longer than they predict.
I changed the 5 little plastic bottles I used only once in that time, after the end of the first year, just because.
You want "proof"? I kept the garage remote inside a wood box screwed to the outside of the garage. Mice climbed up the wood wall of the garage and ate through the box, building nests inside it over and over again. I finally got sick of it, took one of my little bottles, and sprinkled about 2 tsp of the crystals in that box. That was the end of that.
I was in the PNW, where it rains more than half the year, and the RV had no protection. To keep the open bottles out of the rain I put one bottle on the top of each of my four tires (1 on each set of duallys), for a total of 4 bottles, and then 1 bottle in the engine compartment.
I still travel with them and use them when I'm in a grassy park for 3 weeks at a time. Don't know that I need to (probably not), but I have them, so I use 'em.
Their website is ugly and in dire need of updating but this is the real deal, and they will help you.
