How long do wild rats live?

Rats are sociable creatures. The majority of wild rats, including an alpha male, numerous females, and young rats, reside in nests. The dominant man will keep other men away from his female group and will provide for his family.

Many rat families have several nesting locations and travel between them depending on the availability of food and water. For rats, having access to water is critical.

How long do wild rats live?

The age of wild rats varies depending on the species. If a predator, such as a fox or an owl, attacks and kills rats, this age can be reduced at any moment. As a result, their average age is quite low. Rats may survive in the wild for up to one and a half years if they have food, water, and shelter. The black rats have a one-year lifespan, while the brown rats have a two-year lifespan. Some individuals may live to be older than the average.

Rats come in a variety of sizes, shapes, and colors, and their lifespans vary as well. Not all animals are created equal. However, it is dependent not only on the species, but also on the rats’ surroundings. It is exceedingly improbable that rats will ever get hungry because they are all omnivores who eat nearly anything.

Brown rats:

The most common rat is the brown rat. The brown rat, which may be found in farms and open fields, frequently enters our houses and gardens in quest of food and refuge. Brown rats can live up to three years in captivity, but in the wild, they seldom live more than a year.

The female can reproduce five to seven times during this time, giving birth to six to twelve offspring. Each year, around 80 pups are born, and rats can reach sexual maturity at the age of six weeks.

Black rats:

The black rat prefers to live in towns. They prefer to reside in roofs, cavity walls, trees, scrapes in the field, or burrows, where they build shredded-paper nests. Black rats are closely attached to humans, are common in cities, and are skilled climbers.

The black rat is a wild rat that originated in India and has since spread throughout the world. It frequents ports and coastal areas, although it can also be found in cities and towns. The parasite that causes the bubonic plague is carried by black rats. Black rats have a one-year lifespan; however, they can survive up to two years.

Why do wild rats have a short lifespan?

Natural predators of wild rats include owls, hawks, foxes, and coyotes, and many others. Furthermore, wild rats are prone to a variety of diseases and are always on the lookout for food, water, and shelter.

These factors explain why rats enjoy entering our houses and soon become a problem. For wild rats, the average house is the best place to build a nest. Our homes provide them with protection from predators, a warm and comfortable place to nest, and an almost limitless supply of food.

Why do fancy rats live longer than wild rats?

Fancy rats come in a wide variety of colors. Fancy rats might be white, cinnamon, multi-colored, or even blue, but wild rats are usually black or brown. They are distinguished from their wild counterparts not simply by their color. Fancy rats get along well with humans and make excellent pets.

They are intelligent, adapt well to change, and can be taken anywhere. Fancy rats have a greater life expectancy than wild rats. A fancy rat will live for an average of 2-3 years, with some exceptions, up to 4 years.

Their aging is accelerated by a lack of natural predators, consistent food, and access to water and medical care. Most fancy rats acquire joint difficulties, tumors, or other disorders by the age of four, which can lead to death.

The life cycle of wild rats:

Rats are born blind, hairless, and helpless, but they do not remain that way for long. The litter usually has 6 to 10 youngsters, who adapt and mature quickly. The pup’s eyes open after 12 days, and they will be completely developed and weaned in a few weeks.

This means that the planet was saturated with a large number of young, curious, and hungry rats in a short period of time. After three months, rats reach sexual maturity and reproduce for about a year. A pregnant female’s gestation period is 21 days, after which the cycle begins.

A female rat can produce five to seven litters throughout her lifetime on average. When you multiply it by ten pups/babies, you’ll quickly understand that one rat can produce 50 young rats in a year.

It does not account for the fact that it will give birth to fresh offspring in three months when they achieve sexual maturity. Once the young kids have been weaned, wild female rats are bred with their male.

Life of an adult wild rat:

The majority of adult rats’ lives are spent foraging and mating. As a result, they are powerful pests. These animals are nocturnal, meaning they hunt for fresh food sources at night. Their keen sense of smell and ability to squeeze into tight spaces have allowed them to blend in seamlessly in urban environments, where they eat nearly anything.

Rats are pack animals who live and travel together. This means that if you see signs of rats, there could be a lot of them. When male and female pairs branch off into an uninhabited region, packs form.

After the rats have nested, it doesn’t take long for new rats to appear. Male rats swiftly find new companions after mating and do not help to the upbringing of offspring. Despite the fact that wild rats can live for up to two years in the wild, studies estimate that 91 to 97 percent of them die within one year.

Predation, disease, and extreme conditions are the most common causes of death. Adult male rats are more susceptible to cancer and kidney illness than female rats.


According to a survey, the average age of wild rats is 1.3 years. Only 5% of rats are thought to be able to live for more than a year. In general, a rat’s lifespan is very individualized and is mostly determined by its living environment, genetics, and diet. This suggests that a rat can live for two years or more if it is kept in a safe environment with plenty of food and water and has no genetic issues.
