PESTS - MICE
Maine has three type of mice: deer, house and white footed. The mice are small and about 1-2 inches long, excluding tail.They require very little water, obtaining most of their water needs from their food. Mice can consume large quantities of stored seed and grains from farmers and granaries.
The presence of mice can be determined by a number of signs. Droppings may be found along run-ways, in feeding areas, and near shelter. Differentiating between mouse droppings and those of certain insects may be difficult. Mouse droppings are about 1/4 inch (0.6 cm) long, whereas those of cockroaches are usually 1/8 to 1/4 inch (0.3 to 0.6 cm) long and under a magnifying glass show distinct longitudinal ridges and squared-off ends. In comparison, droppings of bats contain insect fragments and are more easily crushed between the fingers.
"A mouse is a small rodent characteristically having a pointed snout, small rounded ears, a body-length scaly tail and a high breeding rate. The best known mouse species is the common house mouse. It is also a popular pet. "
Mice can at times be vermin, damaging and eating crops, causing structural damage and spreading diseases through their parasites and feces. In North America, breathing dust that has come in contact with mouse excrement has been linked to hantavirus, which may lead to Hantavirus Pulmonary Syndrome (HPS).
WHITE FOOTED MOUSE
Primarily nocturnal animals, mice compensate for their poor eyesight with a keen sense of hearing, and rely especially on their sense of smell to locate food and avoid predators.Mice build intricate burrows in the wild. These burrows typically have long entrances and are equipped with escape tunnels/routes. In at least one species, the architectural design of a burrow is a genetic trait.
MANAGEMENT AND PREVENTION
Effective mouse control involves sanitation, mouse proof construction and population reduction. The first two are useful as preventive measures. When a mouse infestation already exists, some form of population reduction is almost always necessary. Reduction techniques include trapping and poisoning.”
The most successful and permanent form of mouse control is to "build them out" by eliminating all openings through which they can enter a structure. All places where food is stored, processed or used should be made mouse-proof. Dried grain and meat products should be stored in glass jars, metal canisters or other resealable airtight containers.
Although mice are easily frightened by strange or unfamiliar noises, they quickly become accustomed to regularly repeated sounds and are often found living in grain mills or factories and other noisy locations. Ultrasonic sounds, those above the range of human hearing have very limited use in rodent control because they are directional and do not penetrate behind objects. Also, they lose their intensity quickly with distance. There is little evidence that sound of any type will drive established mice or rats from buildings because they rapidly become accustomed to the sound.
Although cats, dogs and other predators may kill mice, they do not give effective control in most circumstances. In fact, rodents may live in very close association with dogs and cats. Mice may obtain much of their diet from the pet's dish or from what pets spill.
