In November 2016 I got a 49-3100--it is almost finished. If my Wife ever knew....It was full of nests and droppings. There was even a nest in the old headliner. Did all the vacuuming at the PO's home, so she never knew. The solution is buy liquid peppermint at health food store, put in a cotton ball and wrap in tinfoil. I have done this for the woodpile, shelves in Garage and under the front seat of all vehicles. no more rodents...
