Yeah anything like a chain such as Home Depot or Lowes.... I'm sure there are some local hardware stores left too. I try to patronize a local Mom & Pop shop here. The may not have a million square feet of store to browse but they are very good.
Back to the mice walking on plastic, I too have not heard of this, but now I want to know more
Like I said I have always done a critter perimeter around my garage. Last winter I had my Challenger over at my Mom's for winter. My mom liked to feed the squirrels ( just a BIG mouse ) and so the one day I realized I had peanut shells in the trunk of the Challenger! I thought, what the... then I noticed a mouse sized hole in the trunk divider. Long story short I had the ENTIRE rear on the inside of my car pulled apart to rid myself of what luckily was just 1 mouse. I then one day had to get under the hood of my Mom's daily driver to mind the mice enjoyed the warmth of the motor near the battery. Lucky we had weeded them out before too long. Another trick we learned was that a conventional poison will kill a mice most likely where he is making home. If he is well established, it could be deep in your car! By placing out instant potatoe buds they will fill up on them. Then go in search of water ( hopefully away from you car ).
Then let's just say the buds expand and take care of the bugger.
As far as the winters, they are not that bad... I look at it as time to work on the car!
