I have a 2013 3010DS and had field mice problems the first winter. Most seem to make entry up through the area where the water filter and drains are, pretty much upend the whole right side behind the cabinets and stove. Filled gaps with steels wool and packed/dropped about a box of box of clothes dryer Bounce Sheets everywhere behind drawers, in drawers, bathroom, cabinets, etc. Haven't seen droppings in several months. Heard that mice don't like the smell. Also good to keep a small battery operated radio running.
