The Norway rat is arguably the most important pest of medical significance in human history. Almost everywhere that humans are, rats are right behind them, consuming our refuse and sharing our living space. Rats are vectors for ectoparasites, such as the Oriental flea, that transmits the bacterium that caused the Bubonic Plague that killed millions of people in Europe and the Middle East during the 15th and 16th centuries. Similar outbreaks on a smaller scale have also occurred in the United States, such as the San Francisco plague outbreak from 1904-1907. Rats are vectors for a host of bacterial and viral diseases including jaundice, leptospirosis, and murine tyhphus. Norway rats dig holes in the ground adjacent to structures, and live in close proximity to their human hosts. Aside from transmitting diseases, rats also can cause severe damage to structures and materials by biting, gnawing, and chewing. They also contaminate food by urinating and defecating on stored food. It is estimated that roughly 20% of the world’s food supply is contaminated or destroyed by rats annually!
