How Long Do Squirrels Live? All You Need to Know?️

How long do squirrels live is a great question! The average lifespan varies greatly depending on their species and environment. In the wild, most squirrels can live for about 6 years if lucky. However, they may live a bit longer if they’ve made it past their first year—which can be full of challenges! In contrast, squirrels who live in captivity, like in a zoo, sanctuary, or with a rehabber have been known to reach the ripe old age of 20 years!

What is the Average Age of a Wild Squirrel?

In the wild, squirrels typically have a 6 to 12 years lifespan. Still, unfortunately, a significant portion of the squirrel population does not survive past their first year, with approximately 25% dying before reaching one year. However, in captivity, squirrels can live much longer, with lifespans ranging from 10 to 20 years.

Squirrel Lifespan: How Long Do Squirrels Live?

In the wild, squirrels face numerous challenges, such as predators and harsh weather conditions. As a result, their average lifespan is significantly lower than in captivity, typically ranging from 1 to 6 years.

How Long Do Domesticated Squirrels Live?

Squirrels kept as pets or in captivity, protected from predators and provided with a consistent food source, can live significantly longer than their wild counterparts. Their lifespan may range from 8 to 20 years.

How Long Do Backyard Squirrels Live?

Backyard squirrels, often Eastern gray or American red squirrels, typically live between 2-3 years in the wild. However, reaching that age isn’t a walk in the park!

Young squirrels face many challenges, including predators and harsh weather conditions, so if they make it past their first year, they can live a bit longer.

What is the Oldest Squirrel Ever?

Interestingly, the oldest recorded living squirrel was almost 24 years old (23 and 6 months old), but this is far from the norm. That little fella lived in a protected environment in Wisconsin’s Racine Zoo.

How Old is a Squirrel to Human?

That’s a fun and exciting question! If we consider the lifespan of a squirrel in comparison to a human, it might give us an interesting perspective.

The average lifespan of a squirrel in the wild is about 6 years, while the average human lifespan is roughly 72 years worldwide.

So if we do the math, each squirrel year would be roughly equivalent to 12 human years (72 divided by 6).

This means a 2-year-old squirrel could be considered similar in “age” to a 24-year-old human.

But remember, this is a rough comparison and doesn’t account for differences in development, maturity, or lifestyle between humans and squirrels.

Full-grown Adults9 months old and up

How Long Do Squirrels Live – What Kills Squirrels?

Habitat

The habitat in which a squirrel lives can significantly impact its lifespan. Squirrels living in areas with abundant food sources, suitable shelter, and fewer predators generally have a better chance of survival and longer lifespans.

Predators

Squirrels face various threats from predators in their natural habitat, including birds of prey, snakes, and larger mammals. These predators can significantly impact squirrel populations, particularly juveniles with a lower chance of survival during their first year.

Due to their small size and high numbers, squirrels are often hunted by predators, including snakes, carnivorous mammals, birds of prey, weasels, black snakes, skunks, foxes, hawks, and owls. In addition to natural predators, humans also hunt squirrels for their fur and meat.

Cars – Roadkill Accidents

Squirrels are often killed by cars, particularly in urban areas with a lot of vehicular traffic. Squirrels are not always aware of the danger posed by cars and may dart across roads without looking, putting them at risk of being hit.

Also, squirrels may be attracted to roadsides where food is available, such as discarded fast food, which can increase their risk of being hit by a car.

Illness and Disease

Squirrels can be susceptible to various illnesses and diseases, some of which can be fatal. Some of the most common diseases that can affect squirrels include:

  1. Parvovirus is a highly contagious disease that can cause severe diarrhea and dehydration. It is often fatal in young squirrels.
  2. Distemper: Distemper is a viral disease that can cause respiratory, gastrointestinal, and nervous problems in squirrels. It can be fatal in some cases.
  3. Botulism: Botulism is a bacterial disease that can cause muscle weakness, paralysis, and respiratory failure in squirrels. It is often caused by ingesting contaminated food or water.
  4. West Nile Virus: This is a viral disease transmitted by mosquitoes and can cause fever, headache, and other flu-like symptoms in squirrels. It can be fatal in some cases.
  5. Salmonella: Salmonella is a bacterial disease that can cause severe diarrhea and dehydration in squirrels. It is often caused by consuming contaminated food or water.
  6. Lyme Disease: Lyme disease is a bacterial disease transmitted by ticks and can cause fever, joint pain, and other symptoms in squirrels. It can be fatal in some cases.
  7. Tularemia: Tularemia is a bacterial disease that can cause fever, swollen lymph nodes, and other symptoms in squirrels. It is often caused by exposure to infected animals or contaminated water.

Environmental conditions

Climate, food availability, and disease can impact a squirrel’s lifespan. Squirrels living in harsh climates with limited food sources may not survive as long as those in more favorable environments.

Falling Out of the Nest

Falling out of the nest can be dangerous for young squirrels, as they are born without fur and cannot regulate their body temperature. Additionally, they may be vulnerable to predators or other environmental hazards, such as extreme temperatures or dehydration.

If a baby squirrel falls out of the nest, the mother may abandon it if she perceives that the situation is too dangerous to retrieve her offspring. The mother may also abandon a baby squirrel if she feels that it is sick or weak and unlikely to survive.

In such cases, it’s essential to seek help from a licensed wildlife rehabilitation center, as they have the expertise to care for and rehabilitate baby squirrels until they are ready to be released back into the wild.

Disclaimer: If you find a sick, injured, or orphaned animal, please don’t take on the responsibility of caring for it yourself. Please locate a licensed rehabber in your area, and remember, this is about the animal’s one chance at life.

  1. Love this article! Such a great information for squirrel lover. If it’s possible, pls write the Ep2 of Asian squirrels. Maybe, Finlayson squirrels.

    Can’t wait to see!

    1. Thank you Por, Yes..you knew I was interested when I asked what the squirrels at your park were called!! I will place that topic on the list. Thanks so much for reading.

  2. Very informative information. My only question is in regard to the ground squirrel longevity information. Ground squirrel is extremely general as they are a very diverse taxa with species ranging from the little round-tailed ground squirrels and thirteen-lined ground squirrels to the quite large rock squirrels and California ground squirrels. There are actually about 22 species of grouond squirrels in North America, so mentioning longevity for a ground squirrel: which species are you referring? Due to size differences and habitat preferences, I would think that some species would live considerably longer than others. Many thanks, Greg

    1. Thank you for bringing this to our attention. I have updated the article to reflect a few different species of ground squirrels and their lifespan.
