The squirrel is one of the most popular animals in contemporary Western culture, but it’s not just its adorable features that make them so lovable.

These rodents have been around for some 50 million years and are known to exist on every continent except Antarctica. It’s thought they may even be older than humans!

Squirrels are members of the rodent family – Sciuridae – which includes small mammals such as tree squirrels, ground squirrels, and red squirrels (along with a larger bunch).

The term ‘sciuroid’ refers to any member or descendant from this family including all other types of rodents like chipmunks; these furry friends have lived alongside humankind since their appearance more than five million years ago.

How Long Do Squirrels Live?

There are many squirrels in the world. In their natural habitat, they live anywhere from 5-10 years, but most die much earlier due to being preyed on by predators or contracting diseases introduced either by humans or other animals.

In a study done at Penn State University, it was found that the average lifespan of wild red squirrels is 18 months while gray ones typically last five to ten years before meeting an untimely end which can be attributed mainly to disease brought on through human contact with them for example when people feed them too often so more food.

Average Lifespan in the wild

The average life span of a squirrel is about 3 years. What might seem like an insignificant amount of time can actually mean a lot for the little critters.  The typical lifespan for these creatures is largely affected by their environment, food supply, and disease resistance.

Average Lifespan in the captivity

In captivity, they can live as long as 20-30 years while those who are living in natural habitats usually have shorter lives because they often die from injury or starvation before reaching adulthood.

What is the lifespan of a grey squirrel?

The lifespan of a squirrel is highly variable, with the average age at birth being between 1 and 2 years. Once they have reached adulthood, however, most grey squirrels can live up to 5-6 years or more!

The record for an individual in captivity was 20 whole years!

Do squirrels die of old age?

Sadly, most squirrels die within their first year. The few that make it to adulthood are usually often struck by cars and eaten by predators.

Do squirrels carry disease?

Do squirrels carry disease? Do they pose a threat to humans? What are the dangers of contact with them for humans? These are all questions that people ask when they find themselves standing in front of an adorable, furry little creature.

Let’s start with the most important question: Do squirrels carry disease? The answer is yes! They do carry a number of diseases but only a few of them can be transmitted and are dangerous to humans. There are four types that we will explore here, all found in North America (the black-tailed tree squirrel).

  • One type is salmonellosis which causes fever, diarrhea (possibly bloody), vomiting, kidney failure, and death if not treated.
  • Another common one is typhus which presents as an acute febrile illness with headache, rash over the entire body including palms and soles of feet.
  • Thirdly there’s tularemia is a rare infectious disease. Also known as rabbit fever or deer fly fever, it typically attacks the skin, eyes, lymph nodes, and lungs. This disease mainly affects rabbits, hares, and rodents, such as muskrats and squirrels.
  • Lastly, there’s ringworm which is a fungal infection that’s highly contagious and typically found in wild animals. It usually starts as an itchy red rash with blisters or scales on the skin surface, often accompanied by hair loss.

Key takeaway: Do squirrels carry disease? Yes, they carry a number of diseases but only a few can be transmitted to humans. The most common ones are salmonellosis, typhus, tularemia, and ringworm.

However, there are no recorded cases of infected people from squirrels carrying these diseases due to their small size (except for the rare case of rabies). Nonetheless, it’s good practice not to touch any wildlife and leave them alone so you don’t risk getting sick!

Is it safe to touch squirrels?

Do not attempt to handle an adult squirrel as they are excitable creatures and handling causes intense stress. there could be unknown allergies which can lead to medical problems later on. A stressed squirrel may bite or scratch which can lead to infection.

What Do I Do If I Come Into Contact With A Squirrel?  -If you come into contact with a squirrel, it is important not to touch any wildlife and leave them alone so that you don’t risk getting sick!

What diseases can humans get from squirrels?

Tularemia: The most common causes of tularemia are from an infected animal bite or scratch, handling a sick or dead mammal.

Tularemia is usually transmitted by ticks and can be contracted through the mucous membranes (nose, throat), skin abrasions (puncture wounds) as well as ingestion. Symptoms include fever, headache, and muscle aches but less commonly may progress to ulcers in the mouth/throat area that eventually become necrotizing fasciitis which is often fatal if untreated.

Leptospirosis. This is transmitted when animal urine comes into contact with open wounds or cuts. Symptoms include headache, muscle aches, fever, and chills as well as red/black urine.

Salmonellosis: This is transmitted when animal feces comes into contact with open wounds or through consuming raw eggs contaminated by a rodent’s droppings.

The most common manifestation of salmonella poisoning is diarrhea and abdominal cramps that may lead to dehydration if untreated.

Typhus: One way this disease can be contracted is by being bitten by fleas carried by infected squirrels). It causes high fever which has led it to also been called “ship fever.

” Typhus could result in rashes all over the body – especially on the chest – but will only last about three days before resolving itself without treatment.


The life expectancy of a squirrel in the wild is usually 3-5 years. If it manages to avoid predators, illness, and other dangers that could cause its death, it can live up to 10-12 years.

However, if you’re not so lucky or unlucky as this little guy was (depending on how you look at his situation), your average lifespan may be closer to 2 years!
