They originated in Asia and were spread through shipping and trade. Man is rats' best friend. Rats have long profited from their close association with humans, tagging along as people colonized the Earth. This “commensal” trait is just one of the qualities that have helped rats and mice spread throughout the world.
It turns out, European colonists weren't alone on their ships when they came to the Americas—they also brought black and brown rats to uninfested shores.
Species and description
This group, generally known as the Old World rats or true rats, originated in Asia. Rats are bigger than most Old World mice, which are their relatives, but seldom weigh over 500 grams (17+1⁄2 oz) in the wild. The term rat is also used in the names of other small mammals that are not true rats.
A sudden infestation of aggressive rats can be attributed to several factors: Food Scarcity: Changes in food availability, such as a decrease in waste or food sources due to population shifts, can drive rats to seek new areas for sustenance.
Outdoors, rats face a variety of predators. In these environments, large birds of prey — including hawks, falcons and owls — feed regularly on rodents. Owls are particularly formidable predators, as their nocturnal behavior ensures that they are most active when rats go out in search of food.
What kills rats instantly? Snap type traps are among the most effective and quickest means to kill rats if placed properly and when a large number of traps are used.
California, it turns out, led the nation in searches for rodent-related pest-control searches, followed by Wyoming, Washington, DC, New Mexico and Wisconsin. And it seems a pest problem is plaguing the entire nation. National interest in pest-proofing surged 165% in June 2024 compared to June 2023, Yelp reported.
Rodents native to the United States play an important role in the health of grasslands and forest, and are a major source of food for many predators and scavengers, including hawks, fox, bobcats, and even wolves.
A non-native species to Florida, the Gambian pouched rat is the largest rat in the world. This rat can weigh up to 9 pounds and is usually between 20 and 35 inches in length. These nocturnal rodents typically spend their time on the ground, although they are expert climbers.
They feed on garbage and other discarded items that humans leave behind. Without them, waste would accumulate, posing health risks and requiring more government spending on cleaning efforts. Rats are not just scavengers; they play an integral role in the food chain.
In the wild, rats experience a high mortality and rarely live more than 1 year, though in exceptional cases they can live up to 3 years [0851]. Even in captivity, most animals do not normally live more than 3 years.
Rat bites and scratches can result in disease and rat-bite fever. Rat urine is responsible for the spread of leptospirosis, which can result in liver and kidney damage. It can also be contracted through handling or inhalation of scat. Complications include renal and liver failure, as well as cardiovascular problems.
A female rat typically births six litters a year consisting of up to 12 rat pups, although 5-10 pups are more common. Rats reach sexual maturity after nine weeks, meaning that a population can swell from two rats to around 1,250 in one year, with the potential to grow exponentially.
Rats are incredibly smart animals capable of learning and remembering complex tasks, solving puzzles, and navigating mazes. Scientists have used rats in psychology experiments for over a century due to the similar structure of their brains to the human brain and their decision-making abilities.
Raptors, including hawks, owls, eagles, and falcons, are common rat predators.
'Playground for rats': Chicago crowned 'rattiest city' in America for 10th consecutive year. For the 10th consecutive year, a popular pest control company has crowned Chicago the "rattiest city." Orkin, an American pest control company founded in 1901, announced the "honor" on Monday.

Both ammonia and vinegar have sharp, acrid odors that rats detest. Ammonia mimics the smell of predator urine, creating a sense of danger, and vinegar's acidic smell irritates their sensitive noses.

Rodents do not like the sharp scent of vinegar, so it's believed that it can be an effective rodent repellent. Common advice is to soak cotton balls with vinegar and place them near areas where you think rodents are entering your home and to use vinegar as a cleaning solution.
