Difference between mice and rats

Mice are completely different to rats. It is important you know the difference. In the home, mice are more common than rats.

Before you book check the differences between rats and mice

  • Mouse droppings are similar in size to grains of rice and are scattered.

  • Rat droppings are more the size of baked beans or jelly beans and are usually found in groups.

  • Rats are generally bigger, heavier, longer and darker.

  • Mice have longer, thinner tails (relative to their bodies).

  • Mouse ears and eyes are large in relation to their heads. Rats’ ears and eyes are smaller.

  • Rats can be found outdoors, indoors and in sewers. They leave larger holes.

  • Rats eat almost anything, including meat. Mice prefer nibbling on things like cereals.
