Difference Between Mouse Poop and Rat Poop


Rodents are notorious for causing trouble, whether it is chewing through electrical wires or contaminating food sources. One of the most obvious signs of a rodent infestation is the presence of their droppings. However, it can be challenging to distinguish between mouse poop and rat poop. In this essay, we will explore the difference between mouse poop and rat poop.

What is Mouse Poop?

Commonly grey when old and black when fresh, mouse poop is an important feature in the identification of rodents during an infestation. The quantity of the fecal matter in mice is also substantial, with droppings of 70 to 150 and has a shape of a spindle, and bend with an arch. The most common places where mice poop may be found in the house includes; under the kitchen sinks, in the back of drawers, inside pantries and behind food boxes.

What is Rat Poop?

This has a dark or grey color, depending on whether it’s fresh or old. When fresh, it is soft and dark, while when old, it is grey with a dusty texture. They are curved, with pointed and sausage-shaped ends. The droppings are about 20 -50 pellets, depending on how small or large the rat groups are. Rat poop is commonly found in sewers, garages, rooftops, basements and other damp areas.

Differences: Mouse Poop and Rat Poop

  • Size and Shape − The most apparent difference between mouse poop and rat poop is their size and shape. Mouse poop is typically small, about the size of a grain of rice, and has a pointed end. On the other hand, rat poop is much larger and thicker, about the size of a raisin. The shape of rat poop is also blunt at both ends.

  • Color and Texture − The color and texture of rodent droppings can provide insight into their diet and habits. Mouse poop is usually dark brown or black, while rat poop is brown or black. Mouse poop is granular and has a dry texture, while rat poop is glossy and moist.

  • Location − Another way to tell the difference between mouse poop and rat poop is to look at where it is found. Mouse droppings are usually found scattered randomly throughout an area, while rat droppings are typically found in specific locations. Rats tend to create a central location for their droppings, such as near their nest or along their regular travel routes.

  • Frequency − The frequency of rodent droppings can also help distinguish between mouse poop and rat poop. Mice tend to produce droppings in large quantities, leaving behind a significant amount of poop in a short amount of time. In contrast, rats produce fewer droppings but are more likely to deposit them in the same area repeatedly.

  • Smell − Finally, the smell of rodent droppings can provide some clues as to their origin. Mouse droppings usually have a mild odor, while rat droppings have a much stronger, musky smell. The scent of rat poop can linger in an area for an extended period, making it easier to detect a rat infestation.
