This mouse originally came from Central Asia and was introduced into the United States in the 17th century on ships from Europe. This mouse is now ubiquitous and breeds year round in urban buildings. Field mice and other species of wild mice are generally similar in their behavior and biology. The head and body is about 3 inches long and the tail measures 3 to 4 inches in length. Mice are excellent climbers and can scale almost any wall having a rough surface.
Mice have an extremely well developed sense of touch.
Their whiskers and body hairs help them to navigate at night without bumping into objects. Mice use smell to identify other animals as well as to find food. However, the smell of humans on mouse traps does not repel mice. However, the use of ultrasonic noise to repel mice works about as well as the sound from a jack hammer preventing a nearby worker from eating his or her lunch. Since mice are colorblind, the color designs on traps and baits are there for the benefit of the purchaser.
