Rodents

We are having rodent problems. Thankfully, they are not in the house. Unfortunately, they are outside in our vehicles. We currently have three vehicles. Our truck sits most of the time and maybe gets driven every week or two. I might expect something like that to happen, but I do not expect it in our cars that are driven daily. That just seems odd to me, though I do not call myself a rodent expert in any way. We discovered this problem not by actually seeing any living animals, but because there are acorns in our engines, and some chewed up wiring in the truck. Acorns!?! We have asked people for advice and done some research on the Internet. There is not much information out there to assist us with our problems. We have the silly responses of putting a cat in the car, then a dog to get rid of the cat, followed by a mountain lion to get rid of the dog. (And what gets rid of the mountain lion?) Right now, we are currently trying hairspray. Someone told us to spray our engine with hairspray because they hate the smell. It seems to be working, but only time will tell…
