How To Control Field Mice


Field mice are a common and widespread species and can often be found in close proximity to humans. As such, they are sometimes considered a nuisance. Other names for the species include long-tailed field mouse, common field mouse and European wood mouse.


The field mouse is also known to be a potential carrier of the Dobrava strain of hantavirus, which can be dangerous to humans. As such, caution should be taken when encountering them.




Field mice are found in a variety of habitats, including grasslands, woodlands, hedgerows, and agricultural areas. They are also known to inhabit human dwellings, such as barns, sheds, and garages. They prefer to live in areas that are close to a water source, as they need access to water in order to survive.


Field mice will nest in burrows beneath the ground or in sheltered areas above ground, such as in hollow logs or under debris. They may also build nests out of grass, leaves, and other materials.


What do field mice eat ? 


Field mice feed mainly on seeds, nuts, insects, and other small invertebrates. In the summer, they may also feed on fruits and vegetables. In the winter, they are known to eat acorns, grains, and stored food left in human dwellings. They may also eat bark, leaves, and roots. Field mice will also scavenge for food, particularly in areas where there is a lot of human activity.


Do field mice hibernate? 


Field mice do not typically hibernate, but some will enter a state of torpor during cold weather. During this time, their body temperature and metabolism slow down to conserve energy. 

They will remain in this state until the weather warms up. Field mice are active year-round, but they may become less visible during the winter months as they seek out warm places to shelter. 

In the summer and autumn, they can be seen collecting food, nesting, and defending their territories. They are also nocturnal, so they are most active during the night.


Lifespan of field mouse 


The average lifespan of a field mouse is around 18 months, but they can live up to 2 years in the wild. In captivity, they can live up to 5 years. 


Wood mouse ( field mouse) Behaviour


Field mice are active during the day and night, but tend to be most active during dusk and dawn. They are social animals and live in groups, typically consisting of a dominant male, female and several juveniles. In the summer months, they may form large colonies. 




Field mice are also known to be good climbers and swimmers, and will often use these skills to escape predators. They are also capable of jumping up to 3 feet in the air. They tend to be quite timid and will flee when approached.






The field mouse is preyed upon by numerous predators, including foxes, weasels, cats, snakes, owls, and birds of prey. They may also be killed by humans, either accidentally or intentionally.


Field mice are an important part of the ecosystem, as they are important food sources for a number of predators. They are also important pollinators, as they help to spread pollen from one plant to another. They also provide food for other small animals, such as birds and lizards.

Can it climb a tree?


Field mice are also capable of climbing trees and have been known to build nests in these trees, as well as in other locations such as walls and floors. Field mice have also been observed to use their tail to balance while climbing. Additionally, these mice are able to swim and have been observed to dive underwater in order to escape predators.


How to Control field mice infestation



If field mice have infested your home, there are several steps you can take to help control the problem. These include:


  • Keeping food and garbage in sealed containers to reduce the food source for the mice.


  • Removing any potential nesting sites, such as piles of leaves or other debris.


  • Using traps and/or bait to capture or kill the mice.


  • Seal up any cracks or crevices they may be using to gain entry into your home.


  • Consider using a professional pest control service.


Pest Control Services 


The field mouse is considered a pest species due to its tendency to invade homes and cause damage to stored food and other items. As such, professional pest control services may be necessary in order to effectively rid an area of a field mouse infestation. These services typically employ a variety of techniques, such as trapping, baiting, and exclusion, in order to control the rodent population. In some cases, chemical treatments may also be used.

We thought we had bedbugs but could find no evidence apart from what we thought were bites. I called Bon Accord and Gabriel was there within a couple of hours. He told us we had carpet beetle. Finding the evidence and showing us photos of the skin reaction which was exactly what we had. He advised and returned at a time to suit us to spray which was done thoroughly and efficiently. No sign of the little critters returning. Thank you Gabriel.

Gabriel was absolutely wonderful, a real life saver when I found a mouse by my bed at 10pm. He came in less than an hour and was able to catch the mouse and put my mind at rest so I could go to sleep! Highly recommend, fab service and lovely people.

Gabriel turned up with an hours notice one evening and immediately identified the issued. He works efficiently and professionally throughout with timely follow-ups to ensure the problem was resolved. Once completed he was kind enough to continue to check in to see that the issue had gone. Having had Rentokil previously that spent two years doing very little this was a complete breathe of fresh air and solved the problem in less than two weeks. We are grateful and would highly recommend his services.

We were lucky to have found Bon Accord, they responded very fast to our request and Gabriel was very helpful and informative. He made several visits and did his absolute best until the mice problem we had was gone. Highly recommended.
