How to Get Rid of Borers on Citrus Plant

Citrus plants are vulnerable to a variety of pests, including borers. These pests can cause significant damage to your citrus plants if not managed effectively. Borers are small insects that burrow into the bark and wood of citrus plants, causing damage to the tree’s vascular system. If left untreated, they can kill the plant. In this article, we will discuss how to get rid of borers on your citrus plants.

Identifying Borers

Before you can get rid of borers, you need to be able to identify them. Borers lay their eggs on the bark of citrus trees. When the eggs hatch, the larvae burrow into the bark and begin feeding on the tree’s tissues. The larvae are white or cream-colored and have a small head and a segmented body. They leave behind frass (sawdust-like material) as they feed.

The most common types of borers that attack citrus trees are:

• Citrus longhorned beetle
• Diaprepes root weevil
• Shot hole borer

Getting Rid of Borers

There are several methods you can use to get rid of borers on your citrus plants. Here are some effective ways:

1. Prune Infected Branches

Start by pruning any branches that are infected with borers. Cut at least 6 inches below the visible damage to ensure that you remove all of the infected tissue. Make sure to sterilize your pruning shears between cuts to prevent spreading the infection.

2. Apply Insecticide

You can apply an insecticide to your citrus tree to kill borers. Choose an insecticide that is labeled for use on citrus trees and follow the instructions carefully. Apply it in early spring or fall when borers are active.

3. Use Sticky Traps

Sticky traps are an effective way to capture adult borers before they have a chance to lay eggs. Hang the traps on the tree branches or on stakes near the tree. The traps should be replaced every few weeks.

4. Wrap the Trunk

Wrapping the trunk of your citrus tree with burlap or a similar material can help prevent borers from laying their eggs. Make sure to wrap the trunk all the way to the soil line and secure it with twine or tape.

5. Use Beneficial Nematodes

Beneficial nematodes are microscopic organisms that feed on borers’ larvae. You can purchase nematodes at your local garden center or online. Follow the instructions carefully to apply them to your citrus tree.

Preventing Borers

Preventing borers from attacking your citrus plants is easier than treating an infestation. Here are some ways to prevent borers:

• Keep your citrus trees healthy by providing them with proper nutrition, water, and sunlight.
• Avoid damaging the bark of your citrus trees when you mow or trim around them.
• Remove any dead or decaying wood from your citrus trees promptly.
• Keep the area around your citrus trees free of weeds and debris.
