i went to dollar store, got metal cookie tins,(container with lid) cut mouse hole with razor knife , put in large chuck of rat bait , replaced lid ,glued board to lid, for weight,overhung board to shelter hole from weather, placed container in front and back of each tire with hole facing tire, again to shelter from weather, and they like privacy. tires are the only access point to car, this snack bar will deter mouse from going further up car. only mouse will be able to get in. no traps to clean . PS : I wrapped tape along sharp edges of hole so mouse would't be cut , you know how PETA can be
