Norway rats are one of two common rat species that thrive in North America. The Norway rat, so named because it was erroneously thought to have originated in Norway, is one of the most adaptable species on the planet, second only to humans.
Norway rats are brown to light grey in color and are thick-bodied, with short tails. These rats are excellent swimmers and live in densely populated areas in cities, including sewers. Norway rats will nest in homes near the ground level and will also burrow in the ground near their foundations.
Contrary to their name, Norway rats didn't originate in Norway. They started out in Asia and quickly spread to Europe, stowed away on ships. Eventually, in the late 1700's, they arrived in America and have thrived here, with populations from Florida to Canada.
Norway rats are carriers of a number of diseases and can be very dangerous to humans. These pests are omnivores and will feed on a variety of foods. They will feed at night and often can be found in pantries or garbage cans, where they scavenge for scraps. Norway rats cannot go for long periods without water, so they also look for foods with high water content, such as fruits and vegetables.
If you discover signs of Norway rats in your home, trapping and baiting can work on a small number of pests effectively. Like other rats, Norway rats breed rapidly, so you need to take action quickly. Rats will spread disease through their droppings and urine, as well as their saliva, along with parasites they host in their fur. Take extreme caution when removing rats from your home. Always wear gloves, a facemask and old clothing you can toss after you are finished. However, if you suspect a significant infestation, a call to a professional pest control company is definitely in order.
