I live in the middle of a wooded area. When we built the house the mice moved in when we did. This did the trick. After a year of treatment (24 years ago) there hasn't been a mouse in the house.

it is amazingly odor free

 

I use unscented dyrer sheets. A car-detail guy I know well, told me do not use the scent kind.

 

I use Bounce sheets in my cars during storage and have had no problems, BUT.......

I had a mouse get into my Silverado. It made a nice mess in there chewing up all the papers and nesting in the glove box. I cleaned it up and spread a bunch of sheets throughout the cab. The critter was still in the truck till I got it in a snap-trap.

My final deduction is, Bounce sheets will deter critters from infesting, but if they're already there they won't make them leave.

 

I use Bounce sheets in mine.. Few sheets in the trunk and one on each floor pan area.. Then have bowls of mouse poison at all 4 corners of the car. Knock on wood no mice yet in many years. The poison goes down so I know they are around! I also plug up the air filter opening..
