The roof rat is the smaller of the two commensal rats, as the Norway rat is larger in size. Roof rats are also referred to as black rats or ship rats. The roof rat gets its name from its tendency to find shelter in the upper parts of buildings. Once inside, roof rats not only damage materials by gnawing through them, but they also contaminate stored food and serve as vectors of dangerous diseases.
Roof rats are thought to be of Southeast Asian origin, but they are now found worldwide, especially in the tropical regions. Roof rats are common in coastal states, seaports and the southern third of the country.
The Norway rat commonly referred to as the street or sewer rat, is believed to be of Asian origin, arriving in the U.S. on ships from other countries in the 1700s.

Although not extremely agile, they are capable of running, climbing, jumping and swimming. Norway rats are known to cause damage to properties and structures through their gnawing.
