For those of you that worry about rodents using your truck for a winter condo, I have used Mouse Away for several years with great success. Go here
www.dreamingearth.com and look for Mouse Away products. It is not poison, it is essential peppermint oil and essential spearment oil mixed together, and mice cant stand the smell. Again, it is not poison and not harmful to pets or children. I use this in my vehicles, my house and heating ducts on a regular basis and I have no mice in my vehicles or my house. This stuff really works folks, I buy a half gallon at a time.
I am not associated with this company, just a very satisfied customer.
