Common Types of Mice in the UK

There's several common types of mice in the UK, with different appearances, sizes and lifespans. If you're curious about which type you've spotted in your home or yard or want to learn about UK mouse varieties so you are able to recognise them, check out our mouse identification guide.

House Mouse

House Mouse

The house mouse has brown-grey fur with a long tail covered in hair which are thicker and rougher than the tails of other mouse types. House mice have large ears, small eyes, pointy noses, and tiny feet, which is different from field mice which have big back feet.

When it comes to how long they live, house mice can survive for about a year if they're outside but can live for up to three years if they find a cosy spot inside. House mice munch on about 3 grams of food daily and like to eat cereals as well as fruits, seeds, and grains.

Similar to other mice, house mice don't hibernate. Instead, they are highly adaptable, setting up home where it's warm and close to lots to eat, like in places where people live.

Field Mouse

Field Mouse

The field mouse sports light red-brown fur paired with white feet and chest. These mice stand out with their oversized hind legs, which give them a bouncy walking motion, and a tail as long as their body. Typically, a field mouse lives for about a year due to predators and risky environments. Yet, in safer conditions, they can reach an age of three years.

As for their diet, field mice munch on seeds, fruit, berries, nuts, and mushrooms and occasionally even enjoy a snail. Field mice stay awake and are busy all winter. They don't sleep away during the cold months. Instead, they often sneak indoors for warmth and venture out in search of food when indoor supplies run low.

Field mouse pose a significant health risk to humans and are known carriers of the deadly hantavirus.

Yellow-Necked Mouse

Yellow-necked mouse

The yellow-necked mouse gets its name from the light yellow band of fur around its neck, but you could easily mix it up with a regular field mouse. If you're trying to tell them apart, look for the white spot under their chin—that's the taletell sign of a yellow-necked mouse. These mice are a bit larger than other UK mouse species and can reach a length of about 10 cm.

Generally, yellow-necked mice only live for 3 to 4 months with few reaching 1 year. They are renowned for their ability to acrobatically jump to escape predators such as owls, weasels and foxes. Yellow-necked mice can be found mainly in mature and ancient woodland in Southeast England, the Midlands and some parts of Wales. Regarding food, they like to munch on things like nuts, fruit, seeds, plant shoots, and invertebrates. While yellow-necked mice don't hibernate in winter, they do cuddle together to stay warm, using each other's body heat.

Harvest Mouse

Harvest Mouse

The tiny harvest mouse holds the title of the smallest rodent in all of Europe and stands out as the only British rodent that can grip with its tail. This nifty skill lets it handle objects and zip through tall grass with ease. Speaking of life span, a harvest mouse usually lives for about 18 months, but they can enjoy up to 5 years when looked after in captivity. 

Their diet is quite sweet, as they love munching on juicy fruits, seeds, and sometimes they'll snack on soft bugs like slugs or snails. When it gets cold, harvest mice lay low but they don't go into full hibernation. They prefer to keep snug in their nests, and they stock up on food to help them through the chilly season.
