Do Ants Eat Walnuts

Ants do eat walnuts, and they can actually be quite attracted to them.
 
If you’ve ever left a bag of walnuts out on the counter and noticed a trail of tiny visitors, you already know ants eat walnuts.
 
Walnuts contain oils, proteins, and sugars that ants find irresistible, so it’s no surprise they’ll nibble on them whenever they get the chance.
 
In this post, we’ll look at why ants eat walnuts, whether it’s harmful, and how to keep them away from your stash.
 
Let’s dive in.
 

Why Ants Eat Walnuts

Ants eat walnuts for the same reason they eat most foods: they’re hungry and walnuts are nutritious.
 
Here’s why walnuts are such a popular snack for ants.
 

1. Walnuts Offer Fats and Oils

Walnuts are packed with healthy fats and oils that ants need for energy.
 
Ants are foragers and they’re always looking for calorie-dense foods to bring back to the colony, and walnuts fit the bill perfectly.
 
The oils in walnuts also make them soft enough for ants to chew through, unlike harder nuts or seeds.
 
That’s why you’ll often see ants eat walnuts before they bother with tougher foods nearby.
 

2. Ants Love the Sugary, Nutty Flavor

Ants eat walnuts because they crave sugar and carbs, and walnuts have a subtle sweetness that draws them in.
 
Even though walnuts aren’t as sweet as fruit, they still contain natural sugars that ants can detect.
 
When ants eat walnuts, they’re getting both protein and carbs, which is a balanced meal for a tiny forager.
 
It’s like a little energy bar for them.
 

3. Cracks Make Walnuts Easy to Access

Whole walnuts in the shell are harder for ants to get into, but once the shell is cracked, it’s game over.
 
Ants eat walnuts easily when the nutmeat is exposed.
 
If you leave cracked walnuts or shelled walnuts out, ants will swarm them quickly.
 
Even a small crack in the shell is enough for ants to squeeze through and start feasting.
 

Are Walnuts Harmful to Ants?

Walnuts aren’t harmful to ants in general, and ants eat walnuts as part of their normal diet in the wild.
 
However, there’s a catch you should know about.
 

1. Black Walnuts Can Be Toxic to Some Insects

Black walnuts contain a compound called juglone, which is toxic to some plants and insects.
 
But most ants still eat walnuts, especially English walnuts, without any issues.
 
Juglone is more of a concern for plants growing near black walnut trees than it is for ants.
 
So while black walnuts might deter certain insects, many ants eat walnuts anyway and suffer no ill effects.
 

2. Ants Eat Walnuts Without Dying

In most cases, ants eat walnuts and go about their business as usual.
 
There’s no evidence that walnuts are deadly to ant colonies.
 
So if you’re worried that ants eat walnuts and then take over your kitchen, the real problem is the food source, not the walnuts themselves.
 

How to Keep Ants Away From Your Walnuts

Since ants eat walnuts and love them, you’ll want to protect your stash if you keep walnuts at home.
 
Here are some simple tips.
 

1. Store Walnuts in Airtight Containers

The best way to stop ants from eating walnuts is to seal them up.
 
Use glass jars or airtight plastic containers that ants can’t chew through.
 
This keeps ants from eating walnuts and keeps your walnuts fresher for longer.
 

2. Clean Up Crumbs and Shells

Ants eat walnuts, but they’ll also eat the crumbs and bits left behind.
 
Wipe down counters and sweep floors after snacking on walnuts.
 
Don’t leave shells sitting around because they can still have traces of nutmeat that attract ants.
 

3. Use Ant Baits or Barriers

If ants keep coming back, use ant baits near the source of the trail.
 
You can also create a barrier with cinnamon, vinegar, or diatomaceous earth around your pantry.
 
These won’t kill ants instantly but they’ll discourage them from coming back for your walnuts.
 

4. Check for Nests Nearby

Sometimes the issue isn’t just that ants eat walnuts, it’s that they’ve built a nest close to your kitchen.
 
Look for cracks in walls, under sinks, or near window frames.
 
Seal those entry points so ants can’t get in to eat your walnuts in the first place.
 

So, Do Ants Eat Walnuts?

Ants do eat walnuts, and they’ll happily munch on them any chance they get.
 
Walnuts give ants the fats, sugars, and proteins they need to survive.
 
While walnuts aren’t harmful to ants, you should store yours properly to keep ants from eating walnuts in your home.
 
Hope this post has helped you understand why ants eat walnuts and how to keep them out of your pantry.
