How Long Do Squirrels Live?

Request Wildlife Control

Almost everybody can recognize a squirrel by its bushy tail. Energetic and crafty, it can be entertaining to watch different species of squirrels in your yard. Depending on the time of year, squirrels eat tender leaf buds, wild fruits, nuts and acorns, bird eggs, seed crops, or even tree bark.

Squirrels can become a problem if they abandon trees as their typical nesting location and relocate inside your attic. The diurnal critters are active throughout the day which can be a nuisance. If a female squirrel creates a nest in your attic, you might be wondering how long will this problem last?

What is a Squirrel's Life Expectancy?

Typically, about half the squirrels in a population die each year. Predators like hawks, owls, coyotes, bobcats, and snakes eat squirrels. Parasites, diseases, and falls can kill squirrels. Human interactions like car collisions also threaten squirrels.

Eastern Gray Squirrel Life Expectancy

At birth, the eastern grey squirrel (sciurus carolinensis) has life expectancy of only two years. In the wild, the maximum recorded life span for grey squirrels is 12 years. In captivity, squirrels can live up to 20 years.

Red Squirrel Life Expectancy

The average red squirrel lives five years, though the pests have great difficulty surviving their first year. 9 years is the longest recorded wild red squirrel lifespan.

Fox Squirrel Life Expectancy

On average, fox squirrels live for three to four years. In the wild, the life expectancy is six to seven years.

Ground Squirrel Life Expectancy

The average lifespan for the California ground squirrel is 3 to 4 years in the wild, but they can live as long as 6 years. In captivity, the recorded lifespan for the ground squirrel is 10 years.

Squirrel Life Cycle

Tree squirrels can have two litters a year. Flying squirrels, fox squirrels, and ground squirrels only have one litter a year.

Young are born without fur and aren’t ready to leave the nest for at least a month and a half. By the time two months pass, baby squirrels are typically weaned and on their own.

How Long Do Squirrels Live in a House?

The exact lifespan of squirrels in homes varies. Squirrels live longer in captivity because of the level of care and protection from predators. Squirrels in attics and walls are protected from predators, but they still need to find food and water sources. 

How Long Can a Squirrel Live in an Attic?

If completely sealed in an attic, with no access to food or drink, squirrels most likely won’t live more than two weeks. However, if squirrels are in your attic, it’s a near certainty that there is a breach somewhere in the attic that allows them to come and go as they please. If this is the case, they will be able to survive for far longer.

How Long Can a Squirrel Live Trapped in a Wall?

The answer to this question varies depending on whether or not the squirrel in question has access to food and water. If a squirrel gets trapped in your wall and is totally without food and water, then it will probably not survive for much longer than two days; however, if the squirrel has access to water, they might make it eight days to two weeks.

Squirrel Control

Since squirrels can live for a fairly long time and cause damage when they nest in yards and attics, homeowners usually aren’t pleased to see the pests.

Trimming tree branches away from your roof can help prevent squirrels from gaining access to your home. Installing squirrel deterrents on any bird feeders will make your property less attractive to squirrels. 

In order to avoid the spread of disease or the hassle of finding a squirrel in the house, contact the experts at Trutech for squirrel removal at the first sign of activity.

NEW! Introducing the Home Critter Quiz!

Squirrels are one of the most common animals to get into your attic. You are most likely to hear them running around during the day. Squirrels are known to fall down wall voids and from there they could chew through drywall to get inside someone’s home.
