Rattus norvegicus commonly referred to as Norway rat, common street rat, sewer rat, and Norwegian rat (among other names) is a common rodent found around the world which is believed to have originated from northern China and not Norway as the name might have suggested. Norwegian rats are known for their sharp teeth, blunt noses, and brown fur.
How long can a rat live?
The lifespan of a Norway rat is affected by its environment. A domesticated pet rat can live for up to four years since its environment is favorable. However, like an average mouse, a rat living outdoors has a much shorter life expectancy of about a year.
Wild rats are prone to suffer predator attacks. Furthermore, diseases, lack of food, water source, and proper care all result in a shorter lifespan. Pest control methods like baits, traps, and rat control chemicals also result in a shortened life. A stray rat in your home can live for up to a year with new litter every three weeks so far it has a constant supply of food, which is precisely why you would need to employ rodent control measures to prevent a rat infestation and diseases.
Are rats nocturnal?
Yes, rats are naturally nocturnal! They spend the day sleeping and wake up at night when lesser predators are lurking in the wild and when the darkness can provide them with some cover. Nevertheless, a rat can also get very active during the day. If there is a pile of clutter to conceal its movement or there is an appealing food source, a rat would muster the courage to move out of its crawl space during the day.
What is the gestation period for a rat?
The average gestation period in Norway rats is between 21 to 23 days. Females reach sexual maturity between the ages of 8 and 12 weeks, and pregnancy can be noticed at about 2 weeks of conception. A single litter contains about 8 to 18 pups. Female Norwegian rats can breed all through the year and are capable of producing 12 liters in a year. This can result in a quick rise in rodent population and is one reason you need a pest control company to tackle Norway rats in your home or commercial spaces.
