Rat vs Mouse Droppings
Learn the difference between rat and droppings.
When inspecting for rodent droppings, do not confuse the smaller mice dropping with roach excrement.
- Cockroach droppings are smaller and more slender than mice droppings and have a distinct ridge along the edges.
- The larger American roach dropping is blunt on end.
- Squirrel droppings are similar to rat droppings but have a twist at the midpoint of the dropping.
The droppings on the left are from mice; the ones to the right are from roof rats or squirrels.
Rodent droppings are known to be harmful. Not only do they contaminate foods and cause allergic reactions in people, but they can also transmit bacteria and diseases. The hantavirus is associated with mice droppings through inhalation.
See the safety tips below for inspection and removal of rodent droppings.
Rat droppings are larger than a cooked grain of rice with relatively blunt ends.
Tips for Safe Handling Of Rodent Droppings
- Use gloves and facemasks when handling rodent feces.
- Prevent hazardous particles in the droppings from becoming airborne. Do not stir up dust by vacuuming, sweeping, or any other means.

- Mop or sponge the area with bleach solution.
- Wash hands and clothes thoroughly afterward.
