Rodents in vehicle at trailhead

I've heard that pieces of Irish Spring soap under the hood and under the seats and dash inside will keep the rodents away.

I was told the same thing and put Irish Spring soap bars in my camper one winter. I've got pictures somewhere of the aftermath but the mice around me must be different, they ate the bars of soap. Kind of like a snack to them.
