Norway Rats

What do Norway rats look like?

Norway rats, also commonly referred to as brown rats and sewer rats, have shaggy brown or gray fur, bulging eyes, blunt noses, and close-set ears.  From the tips of their noses to the end of their bald tails Norway rats measure approximately 16 inches and may weigh over a pound.

Where do Norway rats nest?

Outside Norway rats are typically found living and nesting in fields, along riverbanks, in garbage piles and wood piles, and underneath of concrete slabs.  When these rats infest homes and other buildings they are often found nesting in basements, crawl spaces, and behind the walls of ground floors.  They are poor climbers and therefore do not usually infest the upper levels of buildings or attic spaces.

Are Norway rats dangerous?

Yes, Norway rats are dangerous.  They expose people to disease and bacteria including plague, jaundice, rat-bite fever, and salmonellosis.  Norway rats may introduce fleas, ticks and mites as well.   

Damages caused by Norway rats

A Norway rat infestation can lead to extensive damage to structures and belongings.  Like other rodents, Norway rats have front incisors that continuously grow.  In order to prevent overgrowth, they gnaw constantly.  In a home or business, they often chew on wires, pipes, drywall and insulation, other building material and furniture as well as clothing, books and personal belongings.  

Additionally, the burrowing habits of Norway rats can lead to issues with foundations and slabs while their nesting and foraging habits are destructive. These large rodents may also contaminate spaces with their feces and urine. 

How do you get rid of Norway rats?

Norway rats are difficult to exterminate in homes and businesses without the help of professional rodent control specialists.  DIY rat control is ineffective because it typically does not address the root cause of the infestation.
