Difference Between Mice And Rats

While there may not seem to be much of a difference between mice and rats, other than their size and appearance, these two critters are actually very different. In fact, they are entirely different animals, with several different species within each kind. Genetically, mice and rats don't have any more in common than rats and beavers. In this article, we will look at how these two rodents differ from each other but, most importantly, what you should do if you find either of these animals in your home or business.

Size Difference

Mice, from nose to tail, only grow to be around 6 to 8 inches in length, whereas a rat can be as long as 18 inches. And rats, of course, are heavier. An adult mouse weighs around 50 grams, while an adult rat can be as heavy as 350 to 450 grams for females, and up to 650 grams for males.

Shape Difference

Mice and rats have different shapes. The head of a rat is blunt, heavy, and chunky, while the head of a mouse is tiny, triangular, with a pointed snout. A mouse's ears stand straight and round on the top of its head while rat ears appear smaller and flatter.

Different Droppings

Rat droppings, obviously, are larger than mouse droppings, since they are larger creatures, but they differ in shape, as well. Mouse droppings are 4-7 mm long and are pointed at the ends. Rat droppings are closer to 7-20 mm in length and they tend to have rounded ends.

Different Damage

Since rats are larger and heavier, and have larger, stronger teeth, they are able to do more damage than mice. They chew larger holes and can chew through some things that mice generally cannot, things like wire mesh, cinder blocks, brick, aluminum, and even concrete. But don't be fooled. Mice can do a tremendous amount of damage by their chewing as well, especially if they decide to chew on some electrical wiring, which can cause sparks to fly.

Do they require different measures for control?

While mice and rats are entirely different animals, they have many similar habits, and require similar pest management protocols for proper control.
