You can get rid of Japanese beetles on blackberry bushes by handpicking them, setting up traps, spraying neem oil, and applying milky spore to your soil.
 
Japanese beetles on blackberry bushes are a frustrating problem because these shiny green pests chew through leaves, flowers, and fruit with relentless determination.
 
If you’ve been wondering how to get rid of Japanese beetles on blackberry bushes without drenching everything in harsh chemicals, you’re in the right place.
 
In this post, we’ll walk through the most effective ways to get rid of Japanese beetles on blackberry bushes so your plants can finally thrive again.
 
Let’s dig in.
 

How to Get Rid of Japanese Beetles on Blackberry Bushes

Getting rid of Japanese beetles on blackberry bushes comes down to consistency and timing.
 
These beetles emerge in early summer and can skeletonize an entire blackberry bush in just a few days if you ignore them.
 
The good news is that you have plenty of options, and combining a few of them works best.
 
Here are the strategies that actually work.
 

1. Handpick Japanese Beetles Early in the Morning

The simplest way to get rid of Japanese beetles on blackberry bushes is to pick them off by hand.
 
Early morning is the best time because the beetles are sluggish and easy to catch before they warm up and start flying.
 
Just grab a bucket of soapy water, hold it under the leaves, and knock the beetles in.
 
Japanese beetles on blackberry bushes tend to cluster, so once you find one, you’ll usually find a dozen more nearby.
 
Do this daily for a couple of weeks and you’ll seriously cut down the population.
 

2. Set Up Japanese Beetle Traps (Carefully)

Traps can help get rid of Japanese beetles on blackberry bushes, but placement matters a lot.
 
These traps use a floral scent and pheromone lure that draws beetles in from a wide area.
 
If you place a trap right next to your blackberry bushes, you’ll actually attract more beetles to your plants.
 
Instead, set traps at least 30 feet away from your blackberry bushes to lure them away rather than toward your crop.
 
Empty the traps every day or two because a full trap stops working fast.
 

3. Spray Neem Oil on Blackberry Bushes

Neem oil is a solid option when you want to get rid of Japanese beetles on blackberry bushes without heavy chemicals.
 
It works as a feeding deterrent and disrupts the beetles’ hormones, so they stop eating and eventually die off.
 
Spray your blackberry bushes in the early evening when bees and other pollinators have gone home.
 
Focus on the undersides of leaves where Japanese beetles on blackberry bushes like to hide.
 
Reapply every 7 to 14 days while the beetles are active, especially after rain.
 

4. Apply Milky Spore to Your Soil

Milky spore is a long-term solution that targets Japanese beetle grubs living in your lawn and soil.
 
Once applied, it infects and kills the larvae before they ever become the adults that attack your blackberry bushes.
 
It takes a season or two to fully kick in, but it keeps working for up to 10 years.
 
This is one of the best ways to get rid of Japanese beetles on blackberry bushes at the source.
 

Preventing Japanese Beetles from Coming Back to Your Blackberry Bushes

Once you’ve managed to get rid of Japanese beetles on blackberry bushes, the next step is keeping them away.
 
Prevention saves you a ton of work next season.
 

1. Plant Repellent Companions Nearby

Certain plants naturally repel Japanese beetles, and planting them near your blackberry bushes helps a lot.
 
Try garlic, chives, catnip, tansy, or marigolds around the perimeter of your blackberry patch.
 
These won’t eliminate every beetle, but they make your blackberry bushes far less appealing.
 

2. Keep Your Soil and Lawn Healthy

Japanese beetles lay eggs in moist, healthy lawns, so managing your grass matters.
 
Water your lawn deeply but less often, and keep it slightly taller than usual.
 
Aerating and dethatching also discourages the grubs that turn into the beetles that attack your blackberry bushes.
 

3. Cover Your Blackberry Bushes with Row Covers

Floating row covers create a physical barrier that keeps Japanese beetles off your blackberry bushes.
 
Just drape the fabric over your plants during peak beetle season in June and July.
 
Remember to remove the covers when your blackberry bushes start blooming so pollinators can reach the flowers.
 

So, How Do You Get Rid of Japanese Beetles on Blackberry Bushes?

You get rid of Japanese beetles on blackberry bushes by combining handpicking, traps, neem oil, and milky spore for lasting control.
 
Japanese beetles on blackberry bushes won’t disappear overnight, but staying consistent makes a huge difference.
 
Start with the easy methods like handpicking and neem oil, then add milky spore for long-term protection.
 
With a little patience, your blackberry bushes will bounce back and reward you with a healthy harvest.
