Most commonly in southern California and surrounding areas, we encounter the common house mouse or roof rats. There are plenty of other species but these are the most common. The roof rats are very agile climbers and usually live and nest above ground in shrubs, trees, and dense vegetation. Roof rats are sleek, have a pointed muzzle, long ears, and are grey to white in color. When they invade structures, they are most often found in the attics, walls, false ceilings and cabinets. The house mouse is a vary adaptable animal, which thrives under a variety of conditions. They are found in and around homes, and commercial structures, as well as in open fields and agricultural lands. The house mouse is a nibbler and will sample many foods, but prefers to eat cereals and grains. They consume and contaminate food meant for humans, pets, livestock or other animals. In addition to damaging structures and property they can also transmit pathogens that cause disease, like salmonellosis (a form of food poisoning).
Rodent exclusion is the best way to gain full control. Rodent control is highly important to control rodents from spreading disease.
