mice also have eaten bait and died in buildings, leaving a distinct odor. Their fleas, ticks and mites spread disease.

House Mouse (Mus musculus)
House Mouse (Mus musculus)

A mouse (plural mice) is a rodent that belongs to one of numerous species of small mammals. The best known mouse species is the common house mouse (Mus musculus). It is found in nearly all countries and, like the laboMouseory mouse, serves as an important model organism in biology, and is also a popular pet. The American white-footed mouse (Peromyscus leucopus) and the deer mouse (Peromyscus maniculatus) also sometimes live in houses. These species of mice live commensally with humans.

Mice can be harmful pests, damaging and eating crops and spreading diseases through their parasites and feces. In the Western United States, breathing dust that has come in contact with mouse feces has been linked to the deadly hantavirus. The original motivation for the domestication of cats is thought to have been for their predation of mice and their relatives, the mice.

House mice have an adult body length (nose to base of tail) of 7.5–10 cm (3.0–3.9 in) and a tail length of 5–10 cm (2.0–3.9 in); the weight is typically 10–25 g (0.35–0.88 oz). They vary from light brown to black, with short hair and a light belly. The ears and tail have little hair. The hind feet are short compared to Apodemus mice, only 15–19 mm (0.59–0.75 in) long; the normal gait is a run with a stride of about 4.5 cm (1.8 in), though they can jump up to 45 cm (18 in). The droppings are blackish, about 3 mm (0.12 in) long, and have a strong musty smell. The voice is a high-pitched squeak.

As primarily nocturnal animals, house mice have little or no colour vision. They have a sharp sense of hearing and can perceive ultrasound, possibly up to 100 kHz. They communicate both in the human audible range with squeaks (for long-distance warnings), and in the ultrasound range (for short-distance communication).

House mice also rely on pheromones. Most of these are produced by the preputial glands of both sexes and are excreted with urine. The tear fluid of male mice also contains pheromones.[11] Mice detect pheromones mainly with the vomeronasal organ (Jacobson's organ), located at the bottom of the nose.

Control Methods

Traps
Trapping is an effective method of control. It is the preferred method in homes, garages and other structures where only a few mice are present. Trapping has several advantages: 1) it does not rely on inherently hazardous poisons; 2) it permits the user to determine if the Mouse was killed and 3) it allows for disposal of Mouse carcasses, thus eliminating odor problems that may occur when poisoning is done within buildings. However, trapping is useless if the procedures to prevent reinfestation are not followed.

Exclusion, Sanitation
“Excluding” rodents and trapping are the most effective control methods. Rodent baits should be used only to supplement these methods. If there is a repeated need to use baits, it is likely that sanitation and rodent-proofing should be improved. Remember that rodent baits are poisons. Make sure they are registered with the U.S. Environmental Protection Agency and always follow the label instructions exactly. If baits are used indoors, be sure they are labeled specifically for interior use.

Poison Baits (Rodenticides)
Rodenticides are poisons that kill rodents. They can be purchased in hardware stores, feed stores, discount stores, garden centers and other places where pesticides are sold. Do not buy unlabeled rodent baits from street vendors or other uncertain sources. Do not purchase baits that have an incomplete label or one that appears to be “homemade.”

Myth: Mice DO NOT go out for water once a bait has been consumed, the poison will kill the animal wherever it has taken effect, this could mean a wall in your home.

Sound and Electronic Devices
Mice quickly become accustomed to regularly repeated sounds. Ultrasonic sounds, those above the range of human hearing, have very limited use because they are directional and do not penetrate behind objects. Also, they quickly lose their intensity with distance. There is little evidence that sound of any type will drive established mice from buildings or otherwise give adequate control. See Rutgers Fact Sheet on Ultrasonic Devices.

Control by Cats and Dogs
Many mouse problems around homes can be related to the keeping of pets. In fact, Mice may live in very close association with cats and dogs. mice frequently live beneath a doghouse and soon learn they can feed on the dog's food when he is absent or asleep. Although house cats, some dogs and other predators kill mice, they do not usually provide effective Mouse control.
