Why You Need to Remove Insects From Walnuts

It might seem like a small problem, but insects in walnuts can ruin your whole stash if you don’t act quickly.
 
Here’s why it matters so much.
 

1. Insects Spread Fast in Stored Walnuts

Once insects get into your walnuts, they multiply quickly, especially in warm pantry conditions.
 
What starts as a few bugs can turn into a full-blown infestation in a matter of weeks.
 
That’s why learning how to remove insects from walnuts early is key.
 

2. They Contaminate the Nuts

Insects don’t just live in walnuts; they feed on them and leave behind waste, webbing, and even eggs.
 
This makes the walnuts unsafe and unpleasant to eat.
 
Removing insects from walnuts protects both your health and your taste buds.
 

3. It Saves You Money

Walnuts aren’t cheap, and tossing an entire bag because of bugs hurts your wallet.
 
If you know how to remove insects from walnuts properly, you can salvage most of your supply instead of throwing it all away.
 

How to Remove Insects From Walnuts: Best Methods

There are several ways to remove insects from walnuts, and the right one depends on whether your walnuts are shelled or unshelled.
 
Here are the most effective methods.
 

1. Freeze the Walnuts

Freezing is one of the easiest ways to remove insects from walnuts, and it works for both shelled and unshelled nuts.
 
Place your walnuts in a sealed bag or container and pop them in the freezer for at least 48 hours.
 
The cold kills insects and their eggs, making it simple to shake out the dead bugs afterward.
 
This method also prevents future infestations if you store the walnuts in the freezer long-term.
 

2. Boil Unshelled Walnuts

If you’re working with walnuts still in their shells, boiling is a great way to remove insects from walnuts.
 
Drop the walnuts into boiling water for about 5 minutes.
 
The heat kills any insects hiding inside the shells.
 
After boiling, drain the walnuts and spread them out to dry completely before storing them.
 

3. Soak in Saltwater

Saltwater is another simple trick to remove insects from walnuts, especially freshly harvested ones.
 
Mix a few tablespoons of salt into a bowl of water and soak the walnuts for about 30 minutes.
 
The salt irritates the insects, forcing them out of the shells or crevices.
 
Once they float to the surface, you can scoop them out and rinse the walnuts thoroughly.
 

4. Spread Them Out in the Sun

Insects hate heat and light, so spreading your walnuts in direct sunlight can help remove insects from walnuts naturally.
 
Leave them out for a few hours, and you’ll see bugs crawling away.
 
This works best as a first step before using freezing or boiling for a more thorough clean.
 

5. Inspect and Sort by Hand

Sometimes the simplest way to remove insects from walnuts is to go through them manually.
 
Spread the walnuts on a tray and look for signs of bugs, webbing, or tiny holes in the shells.
 
Toss out any nuts that look damaged or infested, and keep the clean ones for storage.
 

Tips to Keep Insects Away From Walnuts

Once you’ve taken the time to remove insects from walnuts, you’ll want to keep them from coming back.
 
A few smart storage habits make a big difference.
 

1. Store Walnuts in Airtight Containers

Insects can chew through thin plastic bags, so use glass jars or heavy-duty airtight containers instead.
 
This keeps bugs out and preserves the freshness of your walnuts.
 

2. Keep Them Cool and Dry

Insects thrive in warm, humid environments, so store your walnuts in a cool, dry place like the fridge or freezer.
 
This also slows down the natural oils in walnuts from going rancid.
 

3. Add Bay Leaves or Cloves

Natural repellents like bay leaves and cloves can help keep insects away from walnuts.
 
Just toss a few into your storage container for extra protection.
 

4. Check Your Stash Regularly

Even with good storage, it’s smart to check your walnuts every few weeks.
 
Catching insects early makes it much easier to remove insects from walnuts before they spread.
 

So, How Do You Remove Insects From Walnuts?

You can remove insects from walnuts by freezing, boiling, saltwater soaking, sun-drying, or simply sorting them by hand.
 
The method you choose depends on whether your walnuts are shelled or unshelled and how bad the infestation is.
 
Once they’re clean, store them in airtight containers in a cool, dry spot to keep insects from returning.
