Rats and mice are both common rodents and regular troublemakers for property owners in the UK. There are few other pests with the same profile as mice and rats; their similar nature means they are often found in similar circumstances. However, there are some crucial differences between the two that property owners should be aware of. Knowing the differences between rats and mice enables you to identify which one is responsible for an infestation on your property and real with the situation as rapidly and efficiently as possible.
The primary difference between rats and mice is their size. Rats are larger than mice and grow to a much bigger size. However, young rats can be similar in size to adult mice. If you encounter a rodent big enough to be either a rat or a mouse, the size of their ears enables you to distinguish between them. Mice’s ears are much more prominent than rat’s ears at every stage of their lives.
Another physical feature that differs between rats and mice is the length of their tails. Mice have longer tails than rats. Their tails are also thin and covered in short hairs. Rat tails are hairless and much thicker than mouse tails.
Another distinguishing trait is their droppings. Mouse droppings are smaller than rat droppings, often no bigger than a grain of rice. Mice will leave their droppings in the back of and on top of cupboards and anywhere else they travel through when leaving their nest to scavenge food. On the other hand, rat droppings are much larger, sometimes the size of an olive or larger. It’s easier to spot rat droppings, and they leave them in much more obvious places than mice do.
If you have rodents in your home, but you don’t know whether they’re rats or mice, the traits outlined above will help you distinguish between them.
