Roof Rats in the North and East Bay of California
In the U.S., roof rats are primarily restricted along the West Coast, the Southeast, and in the coastal states of Washington, Oregon, and California, where they are a relatively serious pest problem. Roof rats are commensal rodents, living near and dependent upon the human habitat for survival. When these rodents infest homes, they can be found in attics, eaves, and rooflines. The most common identifying characteristic of roof rats is their tail. Roof rat tails are hairless and longer than the combined length of their head and body, whereas the tails of other rats are hairy and shorter than their head and body.
Roof Rat Habitat
Roof rats prefer aerial harborages like tree canopies, dense shrubs, and climbing vines. These rats have pads on their feet to facilitate better climbing of narrow vines and limbs, and their tail also assists to balance when climbing high up off the ground. Roof rats generally begin searching for food shortly after sunset, using trees, utility lines, and fences to gain access to attics, overhead garage storage, woodpiles, and other stored goods. Roof rats are nocturnal and scurrying sounds in the attic at night are often the first sign of a roof rat infestation in homes.
Roof Rat Behaviors, Threats, or Dangers
Salmonella, leptospirosis, and rat-bite fever are among the dozens of diseases spread by roof rats. When foraging for food, roof rats contaminate food meant for humans, pets, and livestock. Roof rats are omnivores, eating both plants and animals, and are very fond of citrus fruit. They also favor pet food, pet feces, birdseed, meat, and grease, infesting storage sheds, and BBQs. Besides spreading disease, roof rats may cause extensive damage when nesting in walls and attics. Chewed, exposed wires inside walls can spark, causing interior walls to catch fire.
If you have a roof rat infestation on your property, always contact a licensed rodent control company.
