What are Norway Rats?2/7/2022 The Norway rat is also known as the street or sewer rat. Asian immigrants brought it to the United States during the 1700s on ships from other countries. Norway rats are found around the world today. The Norway rat has poor vision and is colourblind. Despite this, their other senses, such as hearing, smell, touch, and taste, are highly developed. Norway rats can run, climb, jump, and swim despite not being extremely agile. Norway rats damage properties and structures by gnawing at them. How Do Norway Rats Look? Norway rats have bristly brown fur, flecked with black hairs. Generally, their undersides are lighter, with gray, off-white, and even yellow tones. The length of their head and body are coupled together, and they have small eyes and ears. Signs of a Norway Rat Infestation There are several telltale signs when a home is infested with Norway rats. Gnaw marks around the house are one sign of Norway rats. A bite mark or hole that is brand new tends to be rough, whereas older ones wear smooth and are often greasy. An additional sign of Norway rat infestation is the presence of capsule-shaped droppings. A Norway rat's dropping has blunt ends, while a roof rat has pointed ends. How to prevent Norway Rats Norway rats reproduce rapidly, having three to six litters each year. Therefore, it is imperative to prevent an infestation by taking proactive measures, such as Norway rat control. Norwegian rats are drawn to wood piles, so homeowners should store firewood away from structures. Leaky pipes should be eliminated, especially in crawl spaces and basements, as the dampness will attract Norway rats searching for drinking water. Food should also be properly sealed in containers to avoid contamination, which can cause disease transmission. Garbage should also be tightly enclosed in trash cans that are regularly emptied outside the home. If a rodent infestation is suspected, homeowners should keep an eye out for any signs and contact a pest control team. How to get rid of Norway rats A licensed pest control professional is an effective way for homeowners to get rid of Norway rats. Rodent elimination can be accomplished with an integrated pest management (IPM) plan developed by a pest control professional. Norway Rat Education Habits The Norway rat is a social pest that builds shelter near one another. Thus, there are likely to be more burrows nearby if there is one. They have one or more entrance holes, and an emergency exit hole is hidden under grass, debris, and other materials. Norwegian rats usually live outdoors in fields, farms, and structures. Frequently, they burrow in the soil near riverbanks, in garbage heaps and woodpiles. When food and water sources outside become scarce, Norway rats tend to enter homes in the fall. These rodents easily gain access to homes for nesting with a quarter-sized hole. Norway rats are generally found nesting in basements, piles of debris, or undisturbed materials inside a house. Norwegian rats prefer settling on lower levels, but they can occasionally be found in attics, roofs, and other high spots. Threat As Norway rats are known to gnaw through almost anything, they can cause property damage and threaten homeowners. The Norway rat is also a carrier of numerous serious diseases, including jaundice, rat-bite fever, cowpox virus, trichinosis, and salmonellosis. Norway rats can also infest homes with fleas and contaminate food.
