Large rodents, Norway rats are abundant worldwide and 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.
Distinguishable from other rat pest species by their relatively large size, Norway rats have blunted muzzles, tails shorter than the length of their bodies, small eyes, and plump figures. Also known as brown rats, they typically have coarse brown fur with patches of either black or gray mixed in. Norway rats can grow about 18 inches (46 cm) long and weigh an average of 1 pound (454 g).
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 shelter, 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.
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.
Control and Safety
Basic sanitation is essential to the prevention of Norway rat infestations. Regularly cleaning buildings, sweeping up crumbs, and mopping liquid spills all reduce the possibility of attracting the rodents. Fitting trash bins with lids, sealing food in rodent-proof containers, removing clutter from basements and attics, sealing any holes in building foundations, and replacing broken window screens helps ward off Norway rats, as well.
