How To Get Rid Of Peach Tree Borers

To get rid of peach tree borers, you need to act decisively, because these pests can kill your tree if left untreated.
 
Peach tree borers are the larvae of certain moths that burrow into the bark, usually near the base of the tree, and feed on the inner wood.
 
This feeding disrupts the flow of water and nutrients, which weakens the tree and can eventually kill it.
 
If you’re wondering how to get rid of peach tree borers, the good news is that there are several effective methods you can use.
 
In this post, we will walk through how to identify peach tree borers, prevent them from attacking, and get rid of them if they’ve already moved in.
 

How to Get Rid of Peach Tree Borers

Getting rid of peach tree borers involves a mix of prevention, monitoring, and direct treatment.
 
The best approach depends on the time of year and how bad the infestation is.
 
Here are the key steps to get rid of peach tree borers effectively.
 

1. Inspect Your Tree Regularly

Peach tree borers often go unnoticed until damage is severe.
 
Check your tree trunk, especially the lower 12 inches, for signs of peach tree borer activity.
 
Look for small holes in the bark, sawdust-like material called frass, or gummy sap oozing from the trunk.
 
These are clear signs that peach tree borers are present.
 
Early detection makes getting rid of peach tree borers much easier.
 

2. Remove and Destroy Larvae Manually

If you spot peach tree borers, you can sometimes remove them by hand.
 
Use a sharp knife or wire to carefully dig into the bark where you see damage.
 
You’re looking for the larvae, which are white, worm-like creatures with brown heads.
 
Once you find them, remove and destroy them immediately.
 
This method works best for light infestations and when you catch peach tree borers early.
 
After removing the larvae, clean the wound and let it heal naturally.
 

3. Apply Beneficial Nematodes

Beneficial nematodes are microscopic organisms that hunt down and kill peach tree borer larvae.
 
You can buy them at garden centers or online.
 
Mix them with water and apply them to the soil around the base of your tree.
 
The nematodes will seek out the larvae and destroy them from the inside.
 
This is a safe, organic way to get rid of peach tree borers without harsh chemicals.
 
Apply nematodes in the evening when the soil is moist for the best results.
 

4. Use Insecticides Carefully

Sometimes, getting rid of peach tree borers requires chemical intervention.
 
Insecticides containing permethrin or carbaryl can be effective against peach tree borers.
 
But timing is critical.
 
You need to apply the insecticide when the adult moths are active and laying eggs, usually in late spring or early summer.
 
Spray the trunk thoroughly, especially the lower part where peach tree borers lay their eggs.
 
Always follow the label instructions and avoid spraying when bees are active.
 
Keep in mind that insecticides won’t kill larvae already inside the tree.
 
They only work on newly hatched larvae before they bore into the bark.
 

Preventing Peach Tree Borers from Coming Back

Prevention is the best way to deal with peach tree borers long-term.
 
Once you’ve gotten rid of peach tree borers, you want to keep them from returning.
 
Here’s how to protect your tree going forward.
 

1. Keep Your Tree Healthy and Stress-Free

Peach tree borers are more likely to attack trees that are already stressed.
 
Make sure your tree gets enough water, especially during dry spells.
 
Avoid injuring the trunk with lawnmowers or weed trimmers.
 
A healthy, vigorous peach tree is better able to resist peach tree borer attacks.
 
Fertilize appropriately and prune dead or diseased branches to keep air flowing.
 

2. Wrap the Trunk with Tree Guards

Tree guards are physical barriers that prevent adult moths from laying eggs on the trunk.
 
You can buy them or make your own using window screen or heavy paper.
 
Wrap the trunk from the soil line up to about 18 inches.
 
This stops peach tree borers from reaching the bark.
 
Just be sure to remove the guard in winter to check for any larvae hiding underneath.
 

3. Apply a Trunk Spray During Egg-Laying Season

If peach tree borers have been a problem before, consider applying a preventive trunk spray.
 
Use a product labeled for peach tree borers and apply it during the egg-laying window.
 
This creates a protective barrier that kills larvae as soon as they hatch.
 
It’s a proactive way to stop peach tree borers before they get inside.
 

4. Practice Good Orchard Hygiene

Clean up fallen fruit, leaves, and debris around your tree.
 
Peach tree borers and other pests can overwinter in this material.
 
Remove and destroy any infested branches or trunks immediately.
 
Don’t compost them, because peach tree borers might survive and reinfest your tree.
 
Good sanitation goes a long way in keeping peach tree borers away.
 

Signs You Still Have Peach Tree Borers

Even after treatment, you need to stay vigilant.
 
Peach tree borers can be persistent, and reinfestation is common.
 
Watch for new frass, sap oozing, or wilting leaves.
 
If you see these signs, you may need to repeat your treatment.
 
Sometimes, getting rid of peach tree borers takes more than one season.
 
Don’t get discouraged.
 
Keep monitoring and treating until the signs are gone.
 

So, How to Get Rid of Peach Tree Borers?

To get rid of peach tree borers, you need to combine manual removal, beneficial nematodes, and carefully timed insecticides.
 
Prevention is key, so keep your tree healthy, use trunk guards, and maintain good orchard hygiene.
 
It takes some effort, but you can get rid of peach tree borers and save your tree.
 
Stay consistent and keep an eye on your tree throughout the growing season.
 
With patience and the right approach, you’ll successfully get rid of peach tree borers and enjoy healthy peaches for years to come.
