You can remove insects from walnuts by using a few simple methods that are safe, effective, and easy to do at home.
Whether you’re dealing with pantry pests like Indian meal moths or weevils, the goal is to get rid of them without ruining your walnuts.
If you’ve been wondering how to remove insects from walnuts, you’re in the right place.
In this post, we’ll walk through how to remove insects from walnuts using freezing, heat, and other practical techniques.
Let’s get to it.
Why You Need to Remove Insects from Walnuts
Before we jump into how to remove insects from walnuts, let’s talk about why this matters.
Walnuts are a magnet for pantry pests like weevils, moths, and beetles.
These insects lay eggs inside the shells or in stored nuts, and before you know it, you’ve got an infestation.
If you don’t remove insects from walnuts quickly, they can spread to other pantry items.
And eating infested walnuts isn’t just gross, it can also be a health concern.
So knowing how to remove insects from walnuts is a skill worth having.
1. Freezing Is the Easiest Way to Remove Insects from Walnuts
Freezing is one of the best methods to remove insects from walnuts.
The cold kills eggs, larvae, and adult insects without affecting the taste or texture of your walnuts.
Just place your walnuts in a sealed freezer bag or airtight container.
Then pop them in the freezer for at least 48 hours.
When you’re ready to remove insects from walnuts, take them out and let them come to room temperature.
This method works great for shelled and unshelled walnuts alike.
2. Use Heat to Remove Insects from Walnuts
If freezing isn’t your thing, heat is another reliable way to remove insects from walnuts.
You can spread your walnuts on a baking sheet and bake them at 140°F (60°C) for about 30 minutes.
This gentle heat kills any insects hiding inside.
Just be careful not to overdo it, or you’ll toast your walnuts along with the bugs.
After heating, let them cool completely before storing.
3. Sifting and Inspecting to Remove Insects from Walnuts
Sometimes the simplest way to remove insects from walnuts is to inspect them by hand.
Spread your walnuts out on a clean surface and look for small holes, webbing, or live insects.
You can also sift them through a colander to shake out any loose bugs or debris.
Discard any walnuts that look damaged or have visible insect activity.
This isn’t the most thorough method, but it’s a good first step to remove insects from walnuts before using other techniques.
Other Practical Methods to Remove Insects from Walnuts
Beyond freezing and heating, there are a few other tricks to remove insects from walnuts.
1. Saltwater Soak
Soaking walnuts in saltwater can help remove insects from walnuts, especially if they’re still in the shell.
The saltwater forces bugs to float to the surface, making them easy to skim off.
Just dissolve a cup of salt in a gallon of water, soak the walnuts for a few hours, then rinse and dry them thoroughly.
2. Vacuum Sealing
Once you remove insects from walnuts, vacuum sealing them can prevent reinfestation.
A vacuum-sealed bag cuts off oxygen and keeps pests out.
This is a great long-term storage solution after you’ve done the work to remove insects from walnuts.
3. Diatomaceous Earth
Food-grade diatomaceous earth is a natural way to remove insects from walnuts during storage.
Sprinkle a little in your storage container, and it will dehydrate and kill any bugs that come into contact with it.
Just make sure to use food-grade DE and not the kind meant for pool filters.
How to Prevent Insects from Getting into Walnuts
Once you know how to remove insects from walnuts, the next step is keeping them out.
Store your walnuts in airtight containers, preferably glass or heavy-duty plastic.
Keep them in a cool, dry place away from other pantry items that might harbor pests.
If you buy walnuts in bulk, freeze them for a couple of days before storing to kill any hidden eggs.
And check your stash regularly so you can remove insects from walnuts before things get out of hand.
1. Airtight Storage Is Key
The number one way to avoid having to remove insects from walnuts is airtight storage.
Mason jars, vacuum-sealed bags, and quality Tupperware all work well.
2. Keep Your Pantry Clean
A clean pantry leaves pests with nowhere to hide.
Wipe down shelves regularly and throw out any old or infested packages.
This makes it much easier to remove insects from walnuts when you do spot them.
3. Rotate Your Stock
Use older walnuts first so they don’t sit around long enough for bugs to find them.
Rotation is a simple habit that helps you avoid needing to remove insects from walnuts in the first place.
So, How to Remove Insects from Walnuts?
You can remove insects from walnuts by freezing, heating, sifting, or soaking them in saltwater.
Each method works well depending on how bad the infestation is and whether your walnuts are shelled or unshelled.
The key is to act quickly so the bugs don’t spread to the rest of your pantry.
And once you remove insects from walnuts, store them properly to keep pests from coming back.
