Common Mouse Species in the UK: An Eradix Guide

In the UK, various mouse species coexist with humans, sometimes going unnoticed until signs of an infestation become apparent. Understanding the common mouse species in the UK can help in identifying and managing infestations more effectively. Eradix Pest Control offers expert insights into these species, their behaviors, and habitats, providing tailored solutions for your mouse control needs.

House Mouse (Mus musculus)


The house mouse is the most prevalent species encountered in homes and businesses across the UK. It has a dusty grey coat, a tail roughly the same length as its body, and ears that are noticeably large in proportion to its head.


  • Size: Typically 7.5 to 10 cm in length, excluding the tail.
  • Weight: Around 15 to 20 grams.
  • Litter Size: Can have 5 to 6 litters per year, with each litter containing 5 to 8 young.

Habitat and Behavior

House mice are incredibly adaptable, thriving in a variety of environments, particularly in close proximity to human habitation. They are known for their ability to squeeze through small gaps, making any building a potential home.

Signs of Infestation

Signs include droppings, gnaw marks, and the distinctive ammonia-like smell of their urine. House mice are prolific breeders, which can quickly lead to an infestation if not addressed promptly.

Field Mouse or Wood Mouse (Apodemus sylvaticus)


The field mouse, also known as the wood mouse, is slightly larger than the house mouse and has a brown coat with a white underside. Its eyes and ears are proportionally larger, making it easily distinguishable from its urban counterpart.


  • Size: Slightly larger than the house mouse, usually around 8 to 10 cm in length.
  • Weight: Typically 20 to 30 grams.
  • Litter Size: Produces 4 to 7 litters per year, with 4 to 6 young per litter.

Habitat and Behavior

Primarily found outdoors, field mice may venture into buildings in search of food during colder months. They prefer wooded areas and gardens, where they nest in burrows.

Signs of Infestation

Similar to house mice, field mice leave droppings and gnaw marks. However, their outdoor lifestyle means they are less likely to be found within urban dwellings unless the conditions outside become unfavorable.

Yellow-necked Mouse (Apodemus flavicollis)


Similar in size to the field mouse but distinguished by a band of yellow fur around its neck. The yellow-necked mouse is less common but can be found in certain regions of the UK, particularly in wooded areas.


  • Size: Similar to the field mouse, around 8 to 10 cm in length.
  • Weight: Weighs between 20 to 35 grams.
  • Litter Size: Usually has 2 to 3 litters per year, with each litter averaging 4 to 7 young.

Habitat and Behavior

This species prefers mature deciduous woodland and is rarely found in urban settings. Like the field mouse, it may seek shelter in buildings during autumn and winter.

Signs of Infestation

Infestations are rare in urban environments, but signs would mirror those of other mouse species, with the addition of the unique yellow fur making identification easier if spotted.
