Latin Name – Mus musculus
Appearance
House mice are covered in short hair that is light brown or gray to black in color, with lighter bellies. Their ears and tail also bear hair, although much less than their bodies. Adult mice weigh approximately 12 to 30 grams and can grow up to 20 cm from the nose to the tip of the tail. Droppings are rod-shaped and pointed on both ends.
Behavior, Diet & Habits
Normally, the house mouse makes its home in farm fields, grassy and wooded areas, building nests in areas that are dark and protected from the elements and close to a readily available food source.
Very inquisitive in nature, the house mouse will spend the day roaming its territory, exploring anything new or out of the ordinary. When available, the house mouse prefers seeds and nuts in its diet, but this opportunistic feeder will eat almost anything available.
When the temperatures outside begin to drop, house mice, since they don’t hibernate, begin searching for a warmer place to live. Often attracted by the smell of food and the warmth of a structure, the house mouse can use any opening, such as utility lines, pipe openings, and gaps beneath doors, to gain entry into a home.
Reproduction
The house mouse is known for its ability to reproduce very quickly. A single female is capable of producing up to eight litters per year with an average of six pups per litter. After a 21-day pregnancy, these house mouse pups are born naked, blind and dependent upon their mother for everything. At about 21 days the young are weaned from their mother and may begin to take short trips away from the nest to explore their surroundings. Most mice reach sexual maturity at about 35 days of age and begin mating when they are six weeks old.
Signs of a House Mouse Infestation
Sightings
Although more commonly active in the evening, it is possible to see a house mouse roaming in your home during the day. Most often these animals are spotted scurrying along walls or running from a normally undisturbed hiding place.
Droppings
Where there are mice, there are droppings. These small pellets are commonly found anywhere the animals have visited or traveled. Approximately 3 to 6 mm long, the droppings may be rod shaped with pointed ends.
People may confuse house mouse droppings with those of the American cockroach. Even though the general size and appearance of these droppings are similar, mouse droppings usually have hair embedded in them from where the mice have groomed themselves. Roach droppings also are not pointed and usually have ridges running down the sides.
Footprints
As mice explore their territories, they often leave behind footprints or tracks on surfaces. The distinct pattern of a four-toed front foot and a five-toed back footprint are a clear sign that a mouse has passed by.
Gnawing/Chewing
House mice are known for their ability to chew on a wide variety of items. In most cases, shavings and a fresh accumulation of debris is often the first indication of damage. Teeth and gnaw marks can also be found along the edges of frequently traveled routes, on the corners of objects or creating openings into an area.
Burrows/Tunnels
House mice tend to build nests in material that provides a dark and protective environment, such as insulation and other soft materials. These nests are often characterized by openings or tunnels that are free of dust and cobwebs, but may be littered with droppings.
Sounds
During the evening hours, especially when it is dark and quiet, these small animals can often be heard gnawing and scratching within the walls, running across the ceiling and possibly squeaking.
Odor
House mouse urine plays an important role in communicating with other rodents. Oftentimes, rodents will mark an area to attract females or warn off other males. A distinct odor may become noticeable in an area with a large rodent population or when rodents have been present for a long period of time.
House Mouse Control Tips
To prevent mice from entering the home, all cracks, crevices, holes and gaps larger than a pen cap should be sealed with cement or a mixing compound. It is not advised that wood be used to seal these holes, as mice are capable of chewing through those surfaces.
Cleanliness may also have an effect on pest infestations. Be sure to wash dishes immediately following use. Food should be stored in glass or metal containers with tight lids. Mice acquire most of their water from scavenged food particles and no crumbs or morsels should be left on tabletops or floors.
When a home is already infested, prevention methods prove inefficient. The most effective mouse control methods are those administered by trainedprofessionals.
More Information on the Common House Mouse
The house mouse is a small mammal named for its propensity to live within human habitats. Next to humans, the common house mouse is one of the most prevalent mammalian species in the world. Native to Asia, these rodents have spread throughout the world. They are most commonly seen living within or near human habitations. They may also be used as laboratory subjects and contribute greatly to scientific studies.
House mice walk, run and stand on all fours. They can stand on the hind legs, as well, and are supported by the tail, which also provides balance while in motion. The house mouse has a sharp sense of hearing and communicates with other house mice through squeaks. Some of these squeaks are audible to humans, while others extend into the ultrasonic range. The common house mouse weighs between 12 to 22 grams and may grow up 20 cm in length. They are black to light brown or gray in color, with short hair and lighter bellies. source: orkin.com
