The black rat (Rattus rattus) with the brown rat (species of norvegicus) are the two main rat species of concern in North America. Although numerous rodents are called "rats" because of their similar traits and appearance, not all of them are members of the genus Rattus.
Size is frequently the deciding factor when comparing rats and mice. Little muroid rodents are called mice, but larger ones are usually called rats. However, because they lack taxonomy specificity, these common names may be deceptive. The intricacy of the muroid family is demonstrated by the fact that, despite their names, the pack rat and linen mouse are not members of the Rattus or Mus genera.

Various Species of Rats in North America
Brown, black, pack, and marsh rats are the most prevalent types of rats in North America. Since these rodents are commonly found close to human dwellings, it is crucial for homeowners to understand how to identify them, particularly if they suspect a problem. Proper oversight and oversight of these disease-ridden rats are facilitated by accurate identification.
Norway Rat, or Brown Rat
Other names for brown rats include sewer rats, wharf rats, and Oslo rats. They are a big rodent with a tail that is nearly as long as they are, and they may weigh anything from 9 to 12 ounces and grow up to 11 inches. Their coarse fur has a paler underside and varies in color from brown to dark grey. With the exception of Antarctica, they have spread to all continents since their beginnings in China.

These rats naturally reside in underground burrows close to water supplies. For this reason, they are frequently spotted close to sewers, docks, and rivers. They can move underwater because they are strong swimmers who can stay submerged for extended periods of time.
Additionally, they have been known to swim more than 600 meters to achieve certain lengths. Their will go out at night to eat anything they can find because they are omnivorous feeders. Brown rats have limited vision since they are nocturnal, but they have a keen sense of hearing to warn of predators and a great sense of smell to help them locate food.
Various illnesses that can be spread to humans are infamously carried by brown rats. These include hantavirus respiratory syndrome, bleeding fever, malaria, rat-bite high temperatures, and Weil's disease. Additionally, they may act as a reservoir for the parasite Toxoplasma gondii.
Which causes toxoplasmosis. They are a major annoyance in cities because of their indiscriminate diet and opportunistic behavior. With females able to give birth to several litters with six to twelve pups annually, their fertility rate is equally remarkable. Expert intervention is frequently advised to manage and prevent brown rats from settling due to their fast spawning and possible health hazards.
Black Rat (Roof Rat)
Bigger than the brown rat, the black rat usually weighs 6 to 8 ounces and is 5 to 7 inches long with a tail that is 6 to 9 inches long. They can have black, light brown, or even grey fur, depending on the kind. They are known as "ship rats" because they originated in India and have since spread throughout the world on ships that carry cargo to new locations. In pursuit of food, they can reach treetops thanks to their exceptional climbing skills.
Because they can readily raid nests for eggs and young birds, their arboreal lifestyle and diverse diet represent a threat to bird populations. They can nest in trees and access homes through overhanging branches thanks to their climbing ability.
Their second term, "roof rats," comes from their capacity to climb rooftops. These rats are incredibly flexible and can survive in a variety of settings, including cold and tropical ones. They will, however, break into homes in quest of better living conditions because they enjoy eating human food. In order to obtain food inside a house and remain in an area where they won't be disturbed, they will then build their nests in attics and above garages.
Throughout history, black rats have been suspected of carry a variety of diseases, including bubonic plague, which they assisted in spreading throughout the Middle Ages. Additionally, they are carriers of trichinosis, toxoplasmosis, Weil's illness, and typhus. Their quick reproduction and versatility make them a constant problem for both farms and homeowners, even though they are smaller than the Norway rat.
Wood rat, or Packrat
The packrat is a bigger rodent species that is a member of the genus Neotoma. Adult woodrats can grow up to 16 inches in length and weigh 21 ounces. They appear much larger due to their long tails, prominent ears, and enormous black eyes. They can have heavier tones of mixed brown and grey or a lighter creamy brown.
They can be found in all of the western states, including New Mexico, Colorado, and Wyoming, which are located far inland. Packrats are known as woodrats" because they build their nests in the wild using wooden objects like twigs and branches.

However, when they manage to get into human houses, their nesting activity becomes even more damaging. As they gather the resources they need to construct a nest, they have the ability to tear insulation, chew through electrical wiring, and ruin other building materials. Additionally, they have been observed to settle inside car engine compartments.
Packrats eat a variety of foods, including fruits, plants, and anything else that comes to hand. Their habitats are also varied, ranging from rocky crevices where they erect stick barricades to evergreen forests where they may construct nests high in trees.
They are loud rodents that use high-pitched sounds to communicate, making it simple to identify them. Packrats, like other rat species, are susceptible to a number of illnesses, such as Weil's disease, Bubonic plague, Trichinosis, Hantavirus, Arena virus, and Typhoid. They may also include a variety of parasites and germs, including salmonella.
Rice Rat, or Marsh Rat
Medium-sized and primarily found in the Southeastern United States, the Marsh Rice Rat (Oryzomys palustris) is more prevalent along the Gulf and Florida coasts. They are somewhat smaller than the typical black and brown rat, but they seem similar. Males often reach a length of 10 inches and weigh up to 3 ounces, making them slightly larger than females.
The off-white underside and feet contrast dramatically with their short, dense hair, which is usually gray to grayish brown on the upperparts. Marsh rats have characteristics that make them exceptional swimmers and are adapted for their marsh environment. Among these characteristics are webbed digits that enable them to paddle more quickly in the water and a coat that retains air, keeping them buoyant for longer.
Being omnivores, marsh rats consume everything that resembles a swamp. Insects, fish, bird eggs, crabs, and aquatic plants can all be included in this diet. They breed frequently because of their roughly 25-day breeding cycle. With populations peaking in the summer and falling in the winter, their population density varies periodically.
Flooding is one example of an environmental event that can affect their population size. A number of illnesses, including salmonella, hantavirus, leptospirosis, Bayou virus, and rat bite fever, are also spread by marsh rats. They are also known to house the harmful bacterium Bartonella and have been proven to carry antibodies against Lyme disease. Due to the possibility of disease transmission, their close proximity to human habitats can present health problems, as is the case with many rodents.
Strategies for Handling Rat Infestations
A combination of baits and traps can be used to eradicate rats, however do-it-yourself rat control attempts can occasionally fail miserably. Because rodenticide bait systems have inherent issues, rats can learn to escape traps and baits are not the greatest option. Baiting can introduce poisons that pets can consume or kill rats in places they can't get to, leaving behind a decaying body that smells and draws in additional pests.

Because they breed quickly, large-scale infestations can also cause rat populations to quickly take over a property. Because of the harm they do and the infections they can spread, this can lead to a number of issues. Make sure to seek the assistance of experts who can help create a strategic strategy to successfully eradicate the rat problem if it becomes too large to manage.
How to Stop Rats from Coming Back?
Use a multi-pronged approach that incorporates cleaning, sanitation, prevention, and exclusion to keep rats from returning following treatment. Sealing off any openings that rats might have utilized to enter in the first place is the first step in preventing access. This necessitates a careful examination for holes, fractures, and vents that rats could exploit to get inside your house.
Make sure to inspect crawl spaces, attics, basements, garages, and laundry rooms because these areas sometimes have hidden weak spots. Any traces of the prior infection should then be cleaned up and sanitized.
This is important because pheromones found in rat urine have the ability to draw in other rats. Make certain that locations and nests tainted with rat excrement and urine are thoroughly cleaned. After that, take the appropriate safety measures to ensure that food and waste are kept safely in containers and garbage cans with lids that fit tightly.
