The Norway Rat, Rattus norvegicus, is the most common rat we deal with in the United States. They have earned the title of Super Rat from many exterminators in high population cities, like New York City. They also are called by many different names, it all depends where you are from, some of the names we have heard are, barn rat, water rat, common rat, sewer rat, brown rat, wharf rat, and Norwegian rat. The Norway rat is normally a grayish brown color, but can vary in color from pure gray to a red brown color. For most people this is the easiest rat to Identify, as they will see this rat more in daylight when the population is larger than the available harborage areas are. Populations can grow very quickly in your home or buisness, because the young female will start having litters as early as 60 days, a can have between 4 to 7 litters in her life, with each litter having anywhere from 8 to 12 babies each. This means each female can have from 32 to 84 babies during her lifespan. When living in an enclosed enviroment like your home or business, the Norway rat doesn’t have a breeding season; they will breed all year round. When Norway rats are confined to the great outdoors they usually breed in the spring and fall, this will limit the population growth, just a bit.
Norway rats will burrow under sidewalks, house slabs, dumpsters, junk cars and other similar areas. They love to get in basements and lower areas of buildings. You can see that the Norway rat lives underground and in low areas you can then start looking for signs around your home that can be used by these super rats. These rats can climb and will in barns and chicken houses but they prefer to be at or below ground level.
The Norway rat ranges in color from gray to red brown, and will usually weigh from 10 to 16 ounces. The tail will be shorter than the body being only 6 to 8 inches while the body is usually 7 to 10 inches long. (Remember the roof rat tail is longer than its body.) The body is considered to be heavy and thick for its size, and the ears, are relatively small and close to the body. The one thing most people talk about are the eyes, they are large, protruding and BLACK.
The Norway rat likes high protein foods and will eat meats, seeds, and even insects, as they are opportunist feeders. They will not turn a meal down. We have found using tootsie roll candy as bait works very well. We watched a documentary on the TV and when rats found chocolate they would ignore other foods in favor of the chocolate.
