Brown Rat  (Rattus norvegicus)







The brown rat, also known as the Norway, house, or sewer rat, is dull brown in colour and measures between 14" and 18" (35 cm to 45 cm) from nose to tail. It has small, close-set ears, a blunt muzzle, and very sharp teeth.


When are rats most common?

Rats are year-round pests. Under certain conditions, rats can survive outdoors during the winter, however activity and indoor migration increases as weather gets cooler and outdoor food and water sources decrease.


When am I most likely to see rats?

Rats are most active during the evening and remain so until the middle of the night. If food and water are scarce, or in the case of large infestations, rats become active during daylight hours.


Where do rats build nests?

Rats nest in any safe location near food and water. Outdoors, rats burrow into the ground. Indoors, nesting occurs in double walls, between ceilings and floors, in closed-in areas around worktops, and anywhere rubbish is allowed to accumulate.


What are their breeding habits? Do rats multiply quickly?

The average life span of a rat is 18 months. Young are born about 22 days after mating and mature rapidly. Single females may have as many as 6 litters per year, averaging 6 to 14 young each. By three months of age, the young are independent and capable of reproduction. If not controlled, an infestation of rats will rapidly increase.


Please note: that the Black Rat (Ship Rat) has become increasing rare and most rat problems will be the Brown Rat.
