House Mouse (Mus musculus)
House mice are gray or brown rodents with relatively large ears and small eyes. An adult weighs about 1/2 ounce and is about 5 1/2 to 7 1/2 inches long, including the 3 to 4 inch tail.
Environment and Behaviour:
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.
Mice have keen senses of taste, hearing, smell and touch. They are excellent climbers and can run up any rough vertical surface. They will run horizontally along wire cables or ropes and can jump up 13 inches from the floor onto a flat surface. They can slip through a crack that a pencil will fit into (sightly larger than 1/4 inch in diameter).
In a single year, a female may have five to 10 litters of usually five or six young each. Young are born 19 to 21 days after mating, and they are mature in six to 10 weeks. Most mice reach sexual maturity at about 35 days of age and begin mating when they are six weeks old. The life span of a mouse is about nine to 12 months.
Signs of infestation
- Sightings: House mice are usually active in the evenings but can be seen during the day.
- 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.
- 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.
- Burrows: 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.
- Odours: 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.
