There is a great deal of wrong information and ignorance regarding rat control. Many extermination companies and people resort to poison use for rat control, and this is a big mistake.

The most common nuisance rats are the more northern Norway Rat, or Brown Rat, and the more southern Roof Rat, also known as the Black Rat. Rats are commonly associated with urban areas and people. They will go wherever they can find food and shelter, and that often includes buildings. Although they may look large, they need only a tiny hole (the size of a quarter) or a 1/2 inch crack to fit through. Black and Norway rats will consume many different types of plant and animal foods. They also contaminate food with their urine and feces. Rats are carriers of many different types of diseases and sometimes bite. Rats are primarily nocturnal. They keep a surprisingly small home range, and don’t wander about very far. Even though they often live for less than a year, they can and do breed in large quantities.
