House Mouse or Field Mouse
The treatment of every infestation begins by establishing what kind of pest are you dealing with. From this point on you can figure out why it entered your property, from where it may have entered and so on. The answers to all those questions will lead an experienced professional to the actions he has to take to correctly treat the infestation and prevent it from happening again. Today we will look at two species that are quite common in the UK. They are different in many ways, but to the untrained eye, they are practically the same. You will learn how to make a difference between a house and a field mouse.
Who is this post for:
- People dealing with mice infestations;
- People living in rural areas;
- People with big gardens;
- People storing grains for animals on their property.
Difference between house mouse and field mouse
Both of those critters are invading our homes. They may look alike but they do have some specific differences. Not only in their appearance, but in their nature and behaviour as well. Establishing which kind are you trying to get rid of, will give you leverage in the fight. But in order to get that upper hand, you need to be able to tell apart both types of mice.
Some people are having trouble making a difference between mice and baby rats, so you might find this related article useful.
The field mouse (Apodemus sylvaticus)
The field mouse is one of the most widespread species in the UK. Their natural habitat is the woods, that is why the species is also known as (wood mice). These small rodents plant trees in the woods while hiding their seeds in underground burrows and forgetting about them. Field mice are an important part of the woods. They plant trees and provide other habitants of the forest with prey. Nocturnal birds, foxes, coyotes, snakes and others, all feed on tiny brown field mice. This makes them extremely cautions and hard to catch. They won’t just fall in a trap, they will observe that trap for a couple of days before deciding to near it.
What does a field mouse look like
The field mouse has a light brown fur, resembling sand and bright white belly. Their tails are as long as their bodies, thin and with almost no hair on it. The adults will be anywhere from eight to ten centimetres long. Add another 7 to 9 centimetres for their tails and now you have a total of roughly nineteen centimetres. Their weight is just shy of 30 grams. They also have big eyes and ears.
Field mouse facts
They usually don’t infest urban areas, so it is not often that you see a field mouse in the house. Field mice are found only in properties around open fields, forests, big gardens, farms and others. There is usually plenty of food for wood mice in the woods, however, the shelter, warmth and protection of a human house has no match. Infestations usually happen during the cold months. If you haven’t seen any clues that your property is being infested by the arrival of spring you may have a colony in your basement and walls.
Are field mice dangerous
They are. Not only can they cost you a lot of money on repairs caused by those rodents on wooden frames, plastic pipes and cables, but the wood mouse is also a carrier of the “Hantavirus Pulmonary Syndrome” virus. This respiratory illness could be lethal to humans. The bad thing is, that it’s much harder to notice a field mouse infestation. Their nest doesn’t smell, they only get out at night and they may not even feed on your food supply. All of this is making them kind of stealthy invaders. This species pose more danger to commercial properties and storage facilities but will infest homes as well on rare occasions.

The house mouse (Mus musculus)
The house mouse, unlike the field mouse, can infest your property any day of the year. No matter if it is your living space or commercial storage. This particular species of mice have always lived next to human activity. House mice originate from Asia and slowly spread out continent by continent thanks to established trade routes. They are well used to humans and are far more prone to fall for traps than field mice.
What does a house mouse look like
House mice are almost the same size as field mice. From seven to nine centimetres long bodies, plus the same length tail. The colour of house mice is what sets them most apart from field mice. The entire bodies of house mice are grey or light brown. Their ears and eyes are big for their heads. The feet of house mice are small and they can’t jump as far, nor high as wood mice.
House mouse facts
House mice are so accustomed to life around human activity that they just don’t stand a chance in the wild. These mice always seek ways to get inside our habitat and invade it. Our rubbish is what they make nests out of and our stored foods are their food source as well. House mice prefer grained foods but will eat almost anything they can find. Usually, they will devour around three grams of food, but will constantly nibble on other materials to file their front teeth. The biggest benefit those small rodents have, living in our presence, is that we tend to ward off lots of its predators.
Are house mice dangerous
Well actually, statistics-wise they should be more dangerous than field mice because they invade our personal space more often. They also transmit bacteria and diseases and their nests could be quite gruesome and filled with germs. The excrement they leave behind should not be touched with naked hands and even the dust from their nests could be dangerous.
