How To Get Rid Of Worms From Blackberries

You can get rid of worms from blackberries by soaking them in a saltwater or vinegar solution, which forces the tiny larvae to crawl out of the fruit.
 
Yes, it sounds a little gross, but those little white worms are actually the larvae of fruit flies or spotted wing drosophila, and they won’t hurt you if you eat them.
 
Still, most people prefer their blackberries worm-free, and getting rid of worms from blackberries is easier than you might think.
 
In this post, we’ll walk through why blackberries get worms in the first place, how to get rid of worms from blackberries using simple kitchen methods, and how to keep them from coming back.
 
Let’s dive in.
 

Why Blackberries Get Worms

Blackberries get worms because their soft, thin-skinned structure makes them a perfect home for fruit fly larvae.
 
Unlike thick-skinned fruits, blackberries have tiny crevices around each drupelet where insects can easily lay eggs.
 
Here’s what’s really going on:
 

1. Spotted Wing Drosophila Lays Eggs Inside the Fruit

The spotted wing drosophila is the main culprit behind worms in blackberries.
 
This tiny fruit fly has a serrated ovipositor, which lets it saw into ripening fruit and lay eggs directly inside.
 
Within a day or two, those eggs hatch into tiny white larvae, which is when you start seeing worms in your blackberries.
 

2. Overripe Berries Attract More Insects

The longer blackberries stay on the bush, the more vulnerable they become.
 
Overripe fruit releases more sugar and scent, which draws in fruit flies and other pests.
 
That’s why the worms from blackberries tend to show up more often in fruit that’s been sitting out too long or picked late in the season.
 

3. Warm Weather Speeds Up the Lifecycle

Fruit fly eggs can hatch in as little as 24 to 48 hours when temperatures are warm.
 
So during the peak of summer, blackberries can go from clean to wormy almost overnight.
 
That’s why getting rid of worms from blackberries quickly after harvest matters so much.
 

How to Get Rid of Worms from Blackberries

Getting rid of worms from blackberries is all about coaxing the larvae out of the fruit before you eat or freeze them.
 
Here are the most effective methods:
 

1. Saltwater Soak

This is the classic method for getting rid of worms from blackberries.
 
Fill a bowl with cold water and add about one tablespoon of salt per cup of water.
 
Drop your blackberries in and let them soak for 15 to 30 minutes.
 
The salt irritates the larvae, so they wiggle out of the fruit and sink to the bottom of the bowl.
 
After soaking, rinse the blackberries thoroughly under cold running water.
 

2. Vinegar Solution Soak

If you want a more thorough approach to getting rid of worms from blackberries, try a vinegar bath.
 
Mix one part white vinegar with three parts cold water in a large bowl.
 
Soak the blackberries for about 10 to 15 minutes.
 
The vinegar helps dislodge the worms and also kills off any bacteria or mold spores on the surface.
 
Just don’t soak too long, or the berries will start to taste like vinegar.
 

3. Cold Water Rinse and Agitation

Sometimes a simple cold water rinse with a little agitation is enough to get rid of worms from blackberries.
 
Place the berries in a colander and spray them with a strong stream of cold water.
 
Gently toss them around with your hands to encourage any hidden larvae to fall out.
 
This method works best for light infestations.
 

4. Freezing as a Backup

If you’re planning to use the blackberries in smoothies or baking, freezing can help with getting rid of worms from blackberries.
 
Spread the berries on a baking sheet and freeze them for at least 24 hours.
 
The cold kills the larvae, and any remaining worms will be small enough that you won’t notice them after blending or cooking.
 

Preventing Worms in Blackberries

Getting rid of worms from blackberries is one thing, but keeping them from coming back is even better.
 
Here’s how to protect your harvest:
 

1. Harvest Early and Often

Pick blackberries as soon as they’re ripe, and don’t let them sit on the bush too long.
 
The faster you harvest, the less time fruit flies have to lay eggs.
 
Check your bushes every day or two during peak season.
 

2. Refrigerate Immediately

Once you’ve picked your blackberries, get them into the fridge right away.
 
Cold temperatures slow down the hatching process and keep any existing worms from growing.
 
This simple step makes getting rid of worms from blackberries much easier later on.
 

3. Use Fine Mesh Netting

Covering your blackberry bushes with fine mesh netting can block fruit flies from reaching the fruit.
 
Just make sure the netting is secure and doesn’t have gaps.
 
This is one of the best preventive measures for keeping worms out of blackberries in the first place.
 

4. Clean Up Fallen Fruit

Fallen berries on the ground attract fruit flies and give them a place to breed.
 
Pick up any dropped fruit around your bushes and toss it in the trash or compost far from your plants.
 
Keeping the area clean reduces the chances of worms showing up in your blackberries.
 

So, How Do You Get Rid of Worms from Blackberries?

You get rid of worms from blackberries by soaking them in saltwater or vinegar, rinsing them well, and storing them properly.
 
Those little worms are harmless, but no one wants to bite into a berry and find a surprise guest.
 
A quick soak, a good rinse, and a little prevention go a long way toward keeping your blackberries clean and worm-free.
 
Hope this post has helped you with getting rid of worms from blackberries and keeping them out of your harvest for good.
