Will Squirrels Eat Walnuts In The Shell

Yes, squirrels will eat walnuts in the shell, and they absolutely love doing it.
 
If you’ve ever watched a squirrel wrestle with a whole walnut on your lawn, you already know the answer to whether squirrels will eat walnuts in the shell.
 
These bushy-tailed critters are basically tiny furry nutcrackers with an endless appetite, and walnuts in the shell are like a gourmet meal to them.
 
So whether you’re a curious backyard observer or someone wondering if it’s safe to toss whole walnuts outside, here’s the good news about squirrels and walnuts in the shell.
 
In this post, we’ll dig into why squirrels eat walnuts in the shell, how they crack them open, whether it’s safe for them, and what it means for your yard.
 
Let’s get to it.
 

Why Squirrels Will Eat Walnuts in the Shell

Squirrels will eat walnuts in the shell, and there are several solid reasons why this is one of their favorite foods.
 

1. Walnuts in the Shell Are a Natural Food Source

Squirrels have been eating walnuts in the shell for thousands of years, long before humans started leaving bird feeders out.
 
Walnuts in the shell are part of their natural diet, especially for tree squirrels like gray squirrels, fox squirrels, and red squirrels.
 
When fall arrives, squirrels actively hunt for walnuts in the shell to store for winter, so eating them is basically instinct.
 

2. The Shell Keeps the Nut Fresh

One big reason squirrels will eat walnuts in the shell is that the shell protects the nut inside from going bad.
 
A walnut in the shell stays fresh far longer than a shelled one, which means it’s a smarter food source for a squirrel planning ahead.
 
That tough outer shell locks in moisture and flavor, so when a squirrel finally cracks it open, the nut is still tasty and nutritious.
 

3. Walnuts Are Packed With Healthy Fats

Squirrels eat walnuts in the shell because walnuts are loaded with fats, protein, and essential nutrients.
 
Those healthy fats give squirrels the energy they need to scamper, climb, and survive cold winters.
 
A single walnut can deliver a serious calorie punch, which is why squirrels will eat walnuts in the shell whenever they find them.
 

4. Cracking the Shell Is Second Nature

You might wonder how a little squirrel manages to open such a hard shell, but squirrels will eat walnuts in the shell by using their sharp incisors.
 
Their teeth never stop growing, so gnawing through a walnut shell actually helps keep those teeth worn down and healthy.
 
Squirrels typically rotate the walnut in their paws, nibble a groove along the seam, and pop the shell open in minutes.
 

How Squirrels Eat Walnuts in the Shell

Watching a squirrel eat walnuts in the shell is honestly entertaining, and the process is pretty clever.
 

1. They Carry It to a Safe Spot

Before a squirrel eats a walnut in the shell, it usually grabs the nut and dashes to a perch, a fence, or a tree branch.
 
This is why you’ll often see a squirrel eating walnuts in the shell while balanced on top of a fence, safe from predators.
 

2. They Gnaw Along the Seam

Squirrels will eat walnuts in the shell by chewing along the seam where the two halves meet.
 
That seam is the weakest point, so a few minutes of determined gnawing usually does the trick.
 

3. They Cache Extra Walnuts in the Shell

Squirrels don’t just eat walnuts in the shell on the spot, they also bury them for later.
 
This behavior, called caching, is why you sometimes find walnut shells sprouting little trees in your garden.
 
A squirrel that finds walnuts in the shell will often bury several and eat the rest, planning ahead for lean months.
 

Are Walnuts in the Shell Safe for Squirrels?

Walnuts in the shell are safe for squirrels as long as the nuts haven’t been treated with anything harmful.
 

1. Raw Walnuts in the Shell Are Best

Squirrels will eat walnuts in the shell that are raw, but you should avoid giving them roasted or salted ones.
 
Salt and added oils aren’t good for squirrels, so stick with plain walnuts in the shell if you’re feeding them on purpose.
 

2. Watch Out for Moldy Walnuts

Old walnuts in the shell can grow mold, which is dangerous for squirrels.
 
If a walnut looks discolored, smells off, or has a cracked shell with dark spots, toss it instead of offering it to wildlife.
 

3. Black Walnuts Are Fine Too

Squirrels will eat walnuts in the shell even if they’re black walnuts, which have an even harder shell.
 
Black walnuts are actually a favorite for many squirrels because the reward inside is worth the extra effort.
 

So, Will Squirrels Eat Walnuts in the Shell?

Squirrels will eat walnuts in the shell, and they’ll do it happily, quickly, and often.
 
Whether it’s for the healthy fats, the natural fresh packaging, or the simple joy of gnawing through a tough shell, walnuts in the shell are a perfect squirrel snack.
 
So if you’ve got extra walnuts in the shell and a backyard full of squirrels, go ahead and share the bounty.
 
Just keep them raw, fresh, and free of mold, and you’ll have some very happy little foragers on your hands.
