In regards to pest management, there are two common types of mouse in the UK to be aware of:
- House mouse (Mus musculus domesticus)
- Field mouse or wood mouse (Apodemus sylvaticus).
If you come into contact with a mouse, chances are it’s a house mouse.
These mice are known as “commensal rodents”, which refers to them living with or in close proximity to humans. Commensalism is defined as a long-term interaction in which members of one species (ie mice) gain benefits, while those of the other species (ie humans) neither benefit or are harmed. Field mice are much more suited to nesting outdoors, but will possibly move indoors once the weather gets colder.
The house mouse has a typical mouse profile: small feet with big eyes and thinly-haired ears and a pointed snout with thin whiskers. Their body length ranges between 60-90mm, and the tail generally equals the length of its body, adding another 90mm.
They weigh less than 25g, and their fur colour is uniformly light brown and grey, right down to the tail which has sparse hairs on it. And keep those pegs handy – they have a really distinctive, strong smell so you’ll know if you have a large infestation of these unwanted guests.
