Mouse Droppings in the Home

Mice in the New England states tend to invade homes in search of new food sources or harborage/nesting sites once the weather cools. Once mice find places to nest indoors, homeowners may begin to notice fecal matter in areas frequented by the rodents.

What Does Mouse Poop Look Like?

Mouse droppings typically look like grains of dirty rice. Droppings are often 3 to 6 millimeters in length, rod-shaped, and black or dark brown in color, though this may vary depending on the diet of the mouse. Most droppings taper at both ends and harden the longer they sit.

Where Can You Find Mouse Poop?

Homeowners frequently find mouse droppings in areas of high pest traffic. Mice may deposit as many as 75 to 80 droppings a day as the rodent explores the environment in search of food. Mouse droppings are often found along baseboards, near cardboard boxes, or on any other accessible surface near a food or nesting source.

As timid creatures, mice typically keep away from open spaces, making it possible for droppings to be found during renovations or construction, as the rodents may take up residence in house walls or insulation. In cases of serious infestation, it may become necessary to contact local pest controllers to eradicate the issue, as home traps may become expensive and less effective.
