Norway Rat (Rattus norvegicus)
Rats - General Information
 The Norway rat is the largest of the commensal rodents and the most common to be found in the New England area. The adult's overall length can be up to 2' long, with the average body of about 7" to 10" long and a tail of 6" to 8" long. The fur is course and shaggy, usually dark brown with black hairs and the underside is light gray. Once adult, the rat lives an average of about one year, but can live longer due to their environment.

 Norway rats reach maturity in 2 to 5 months of age. Rats are social animals and after mating, a female's pregnancy lasts an average of 21 to 25 days. A litter contains usually 7 to 8 young and they are weaned at about 3 to 4 weeks. The female typically has about 3 to 6 litters per year.

 Rats are primarily nocturnal and will usually travel about 150' to 200' from their harborage in search for food. They nest along river banks, in sewers, dense vegetation or ground burrows, under concrete slabs, etc... and inside buildings they prefer lower level or basement areas with piles of debris, storage items or merchandise, but can be found occasionally in higher areas and attic areas as well.

 They constantly and cautiously explore their surroundings and shy away from new objects and changes. They will eat practically anything of nutritional value and will also gnaw through almost anything including hard plastic or even soft lead pipes to obtain a food source.

 Aside from damaging building materials or contaminating food, the Norway rat is also of human health importance as a vector or carrier of diseases. Their droppings can be identified by usually 3/4" long, black and capsule shaped with blunt ends.
