Large rodents, Norway rats are abundant worldwide and are known as especially unfavorable pests. As carriers of disease, rats pose great risks to humans merely by occupying the same areas. In addition to being health hazards, Norway rats damage their surroundings when they collect materials for nests and forage for food.


  • Relatively large
  • Blunted muzzles
  • Tails shorter than the length of their bodies
  • Small eyes
  • Plump figures
  • Typically have coarse brown fur with patches of either gray or black mixed in
  • Can grow about 18 inches long and weigh an average of 1 lb.


As they inhabit each continent of the world except Antarctica, Norway rats have proven themselves to be highly adaptable creatures. Since humans provide Norway rats with readily available sources of food and water, as well as suitable shelters, the rodents hold a cosmopolitan distribution and are prominent in major cities with bustling human activity. Adept burrowers, the rats tend to nest underground or in other covered places that offer shelter from predators.

Entry and Damage

Are Norway rats known to enter homes or yards?
Norway rats often find their way into buildings. Human waste provides them with their favorite foodstuffs, like meats, grains, fruits, and nuts, so it is not uncommon for the animal to orient themselves around landfills, dumpsters, and trash bins. Though Norway rat infestations are common, humans may not be aware of the rodents because they are mostly nocturnal. Spotting rats during the day typically indicates large numbers of the pest are present. Signs of Norway rat infestation include plentiful droppings, noises like frequent scratching or scampering, burrows near house foundations, and the bodies of deceased rats.


Do Norway rats harm people or property?
In addition to sullying their surroundings, Norway rats bite and scratch when they feel threatened. Since they transmit several serious diseases, Norway rat bites and scratches leave humans susceptible to any number of viruses, including rat-bite fever, the plague, and lymphocytic choriomeningitis (LCMV). The rodents may also carry smaller pests like fleas. Finally, as accomplished burrowers, Norway rats damage building foundations and sidewalks and gnaw on a variety of objects, leaving behind unseemly teeth marks. If you or someone you know has been hurt by a Norway rat, call a professional immediately.
