RatAs cute as our picture of the common rat or Norway rat may be, they are a destructive, disease ridden pest that must see immediate removal from your home. The Norway rat lives wherever humans live, particularly in urban areas. The fur is coarse and usually brown or dark grey, the underparts are lighter grey or brown. Typical length can be up to 10 inches, not counting the tail which is the same length as the body. Rats have acute hearing and are sensitive to ultrasound, and also possess a very highly developed sense of smell. Their vision is poor thus the reason they are typically seen running along baseboards or other straight line architecture. The Norway rat is a true omnivore and will consume almost anything. They are usually active at night, are good swimmers but poor climbers. They dig well, and often excavate extensive burrow systems.

The Norway rat can breed throughout the year if conditions are suitable, a female producing up to five litters a year. The gestation period is only 21 days and litters can number up to fourteen. Norway rats carry some diseases, including Weil's disease, cryptosporidiosis, Viral hemorrhagic fever (VHF), Q fever and hantavirus pulmonary syndrome. They can also act as reservoirs of bubonic plague.
