Signs of House Mouse Damage

Droppings, gnaw marks, and urine odors are just a few signs of mice activity.

Droppings

Droppings are the most commonly encountered evidence of rodent activity. Even a small mouse infestation can produce literally thousands of droppings in a short period of time.

An adult house mouse typically produces 50 to 75 droppings per day. These fecal pellets are usually dark-colored, 1/4 inch in length, and pointed at both ends.

Gnaw Marks

Evidence of recent gnawing is an excellent sign for determining the presence of mice.

Besides chewing wires, mice gnaw on plastic items, wood, corners of cereal boxes and bags. Additionally, they will shred paper for nests from books and paper towels.

Mouse damage holes are typically small, clean-cut holes about 1/2 inch in diameter.

Sounds & Odors

Another indication that mice are present is a strong musty odor. Cats and dogs may excitedly sniff and probe an area where rats or mice are present, and often indicate this by scratching or making unusual sounds.
