Field Mice

Facts, Identification & Control

What is a Field Mouse?
Field mice is a term used for a variety of mice found in the U.S. including house mice (mus musculus). As the name implies, they are common in fields, which is also true of many other mice species.

However, several species may also be found dwelling in the plains, forests and in old, rural homes.

Mice range in color depending on species and can be brown, black or white in color, with tails of varying length. They are extremely curious.

How Did I Get Field Mice?

The common name field mice includes a wide variety of small rodents and one of the most important is the domestic house mouse. These rodents possess an almost unbelievable ability to get into homes since they are able to climb, jump, swim, and gnaw their way into structures. They often enter through open doors or windows, holes in roofs, plus holes in foundations and siding that are more than only ¼ inch in diameter. After getting inside, they usually nest in attics, walls, voids under and behind cabinets and even under appliances.

These rodents are highly aware of their surroundings and spend time exploring their environment. They eventually memorize pathways as well as where to locate food and shelter. This allows them to find entry points into houses in almost any situation and once inside, navigate a familiar environment at nighttime.

How Serious Are Field Mice?

In some cases, field mice cause extensive damage when they enter homes. For example, they contaminate stored foods with their feces or urine and gnaw on food containers and other items inside the home. Mice also can cause fires should they gnaw on electrical wires. Homeowners with field mouse infestations are at risk for food poisoning, tick-borne diseases, and other health issues. Field mice can also bring fleas and mites inside if they infest the home.

The pests also chew through wires, rip up insulation, and destroy stored items in attics and garages. Fecal droppings, rub marks left by their oily fur rubbing up against surfaces, plus gnaw marks on wood, wiring, or plastic are often the first signs of a field mouse problem in homes.

Diet & Behavior

Many mice are scavengers that will feed on any food available to them.

These mice are prey to cats, dogs, bears, wolves, snakes, owls and rabbits.

Nocturnal in nature, they are cautious and venture outside only after having fully assessed their surroundings.

Mice use their coats as camouflage, blending in with rocks or dried leaves.

Despite this, these mice are often consumed by their predators. Most field mice do not survive to their second year.

Reproduction & Life Cycle

Females are able to become pregnant every month. Baby field mice are born blind, bald and deaf. However, within several weeks, they will have reached maturity and begin mating.
