Norway Rats

Where they live: constructed nests in the ground and structural elements of buildings and city utility systems

About the Pest:

Norway rats are hardy, aggressive, adaptable, and sly mammals. They construct nests in the ground with burrow systems often using structural elements of buildings and city utility systems. Norway rats are nocturnal and feed on almost anything edible. They are unable to vomit which makes them very susceptible to rodenticides.

The Norway rat has gray brown fur on the back and gray white fur on the belly. They weigh up to 20 ounces and are between 7.5 to 10 inches long not including the tail, which is between 6 and 8.5 inches.

How to Control:

Sanitation is very important when controlling any rodent. Debris around the building should be cleaned, garbage should be well-sealed, and dog food should be cleaned up and sealed well. Bait boxes with rodenticides and traps should be used to eliminate existing rats. They should be placed strategically for best results. Rats are leery of new things placed in their environment so a variety of control methods, traps, and baits should be used.
