The Norway Rat is common in most parts of Canada. Rats attach the foods of man from the farm fields and orchards through the processing, storage and retail sales market.

They have a brownish gray upper body and a light grayish underbelly colour. They have small eyes and their tail is shorter than the combined length of their head and body. Average weight is 7 to 17 oz.

Rats have a life expectancy of about 9 months, but a female will have anywhere from 5 to 12 litters per year, with an average litter size of 7-11 young.

They are very agile climbers, excellent swimmers, and very suspicious and wary of the new objects, i.e. traps and bait stations

They normally feed at night but once the population gets to be of a significant size they will feed during the day. Their teeth grow continually so the rat has to gnaw on objects, i.e. wood, pipes, and other objects to impede their growth.
