Will Squirrels Eat Walnuts In The Shell

Squirrels will absolutely eat walnuts in the shell, and for them, it’s like finding a treasure that comes with its own little puzzle.
 
There’s something incredibly satisfying about watching a squirrel wrestle with an unopened walnut, and if you’ve ever asked yourself, “will squirrels eat walnuts in the shell?” the answer is a resounding yes.
 
In fact, walnuts in the shell are one of the best treats you can offer these bushy-tailed foragers because the shell keeps the nut fresh and gives them a fun challenge.
 
In this post, we’ll crack open the details on why squirrels eat walnuts in the shell, how they manage to get inside, and what kind of walnuts are safest to share with them.
 
Let’s get to it.
 

Why Squirrels Will Eat Walnuts in the Shell

Squirrels will eat walnuts in the shell because their bodies and instincts are perfectly built for it.
 
Here’s why this nutty snack is such a natural fit:
 

1. Their Teeth Are Made for Cracking Nuts

A squirrel’s incisors never stop growing, which means they need to gnaw constantly to keep those teeth worn down and healthy.
 
A hard walnut shell is the perfect chew toy and meal combined, giving their teeth a real workout while they work their way to the meat inside.
 
That’s why squirrels eat walnuts in the shell so eagerly, it’s basically dental care and dinner rolled into one.
 

2. The Shell Keeps the Nut Fresh

When a walnut stays in its shell, the kernel inside stays protected from air, moisture, and mold.
 
This means the nut tastes better and lasts longer, which is exactly why squirrels will eat walnuts in the shell when they find them.
 
In the wild, that natural packaging is a big deal because a fresh walnut can be buried and saved for later without spoiling quickly.
 

3. It Matches Their Natural Foraging Instincts

Squirrels are hoarders by nature, and walnuts in the shell are the ultimate item to stash.
 
They can carry them in their mouths, bury them in the yard, and dig them back up months later when food is scarce.
 
So when you offer walnuts in the shell, you’re not just feeding a squirrel, you’re tapping into millions of years of survival behavior.
 

4. The Challenge Keeps Them Entertained

Squirrels are smart, busy little creatures that get bored easily.
 
A shelled walnut gives them a task to focus on, and they’ll turn it, nibble it, and find the weak spot until it finally opens.
 
That mental and physical stimulation is a big reason squirrels eat walnuts in the shell with such determination.
 

How Squirrels Get Walnuts Out of the Shell

Watching a squirrel open a walnut is honestly impressive, and they have a few clever tricks up their furry sleeves.
 
Here’s how they pull it off:
 

1. They Chew Around the Seam

Every walnut has a seam where the two shell halves meet, and that’s the weak point squirrels target first.
 
They gnaw along that line until it weakens, then twist and pry until the shell splits open.
 
It might take a few minutes, but a determined squirrel will get to that nutmeat every single time.
 

2. They Use Their Paws as Tools

Squirrels have surprisingly dexterous front paws that work almost like hands.
 
They’ll hold the walnut steady, rotate it, and reposition it as they chew, which helps them find the best angle to crack it.
 
This teamwork between paws and teeth is exactly why squirrels eat walnuts in the shell so efficiently.
 

3. They Sometimes Drop Them from Heights

On occasion, a squirrel will carry a walnut up a tree or onto a fence and drop it onto a hard surface below.
 
The impact can crack the shell just enough to make opening it easier.
 
It’s not their go-to method, but it shows just how resourceful these animals can be when a walnut refuses to cooperate.
 

Are Walnuts in the Shell Safe for Squirrels?

Walnuts in the shell are safe for squirrels as long as they’re plain and natural.
 
Here’s what to keep in mind before you share:
 

1. Skip the Salted or Flavored Kind

Salted, roasted, or flavored walnuts can be harmful because the added salt and seasonings aren’t good for a squirrel’s tiny system.
 
Always go with raw, unsalted walnuts in the shell for the safest treat.
 

2. Watch Out for Moldy Shells

Old or improperly stored walnuts can grow mold inside the shell, which is dangerous for any animal.
 
If a walnut looks discolored, smells off, or feels unusually light, toss it instead of offering it to a squirrel.
 

3. Feed Them in Moderation

Even though squirrels will eat walnuts in the shell happily, they don’t need an endless supply.
 
A few walnuts a day is plenty and keeps them coming back for more without overloading their diet.
 

So, Will Squirrels Eat Walnuts in the Shell?

Squirrels will eat walnuts in the shell, and they’ll enjoy every bit of the challenge that comes with it.
 
Their teeth are built for cracking, the shell keeps the nut fresh, and the whole process satisfies their natural foraging instincts.
 
Just remember to offer raw, unsalted walnuts in the shell and keep an eye out for any that look moldy or spoiled.
 
Hope this post has helped you understand why squirrels eat walnuts in the shell and how they manage to get to that tasty treat inside.
