Those little bastards are incessant ! I hate to say it, but now that they have left their calling card, mice will forever be drawn to your vehicle. I suggest cleaning and disinfecting every area where possible. Also, I recommend setting traps to eliminate them from going back into the vehicle. In my experience, using dryer sheets and/or moth balls is a myth. Additionally, I would not recommend using poison, as this may only lead to them dying somewhere in your vehicle. Don't ask me how I know all of this.
