Well i just picked up my 500sl (84?) last week and i have never had mice in my garage before even though i keep two traps with peanut butter for bait set all the time.Well at xmas time i had some wreaths chewed on in my storage shed so i got some d-con and put one in the garage just in case.Yup you guessed it .I must have bought mice with the car because i found one on floor of car dead and one near my garage steps. I hope the guy that sold me the car didnt charge me for the little rats(mice). Keep d-con in car now.
