Oak Tree Borers Info
Oaktree borers are a type of beetle that targets oak trees, especially stressed or damaged ones. They reproduce by depositing their eggs within the tree’s bark. Upon hatching, the larvae start consuming the inner bark and sapwood of the oak tree. The actions of these larvae sabotage the tree’s structural integrity and tree’s demise.
Some of the common types of oak tree borers are:
- The Red Oak Borer (Enaphalodes rufulus)– These long-horned beetles target live oak trees, causing cosmetic damage to the trunk and branches. The red oak borer has a two-year life cycle.
- Oak Pinhole Borer (Platypus cylindrus)– This small beetle attacks oak trees and other hardwood tree species.
- Gold-Spotted Oak Borer – Agrilus auroguttatus is native to the oak forests of Southeastern Arizona. It feeds on the sapwood and phloem.
- Two-lined Chestnut Borer (Agrilus bilineatus)- This beetle attacks red, black, white, and bur oaks, causing discolored foliage and wilting of branches.
How to Identify Oak Tree Borers?
Check out the below signs to recognize the presence of oak tree borers:
- One of the major telltale signs of oak tree borer infestation is the presence of D-shaped exit holes in the bark.
- Presence of a sawdust-like substance called frass on the bark exterior or on the wood surface.
- The larvae of borers often cause noticeable damage to the bark. You can easily see discoloration, cracks, splits, or lifted areas of bark. Furthermore, crown thinking and dieback also happen.
- An increase in woodpecker activity around oak trees indicates the presence of wood-eating borer infestation.
- When the oak tree’s sapwood is destroyed by these pests, you might observe sap or resin seeping from its trunk.
DIY Oak Tree Borers Treatment Recipes
Before using these DIY oak tree borers treatment options, first read the precautionary tips mentioned later in this article.
1. Grow Garlic
Growing cloves of garlic around the oak trees wards off the unwanted adult borer beetles. This method works because of the garlic’s potent aroma.
2. Bacillus Thuringiensis
Bacillus thuringiensis (BT), a gram-positive bacteria, is a potent microbial insecticide against oak tree borers. There are multiple forms of BT insecticides. Make sure to use this product according to the manufacturer’s instructions.
3. Soapy Solution
Dawn dish soap is a cost-effective and readily available treatment option for oak tree borers. Begin this hack by combining 3-5 teaspoons of liquid dish soap and a gallon of water in a garden sprayer. Shake the solution a bit and coat the tree’s trunk and branches. Redo this remedy every 14-21 days throughout the growing season.
4. Try Neem Oil
Neem oil, an organic pesticide, is highly effective for the oak tree borers treatment DIY. To create a potent concoction, blend 4-6 tablespoons of this natural oil into 1-2 gallons of water. Once combined, spray this mix all over the tree’s trunk and branches. Redo this remedy every 14-21 days throughout the growing season.
5. Bordeaux Mixture
Bordeaux mixture is an excellent fungicide and bactericide against numerous pests, including oak tree borers. It’s a combination of copper sulfate, lime, and water. To try this treatment option, mix 3-4 pounds of each copper sulfate and hydrated lime in 8-10 gallons of water. Transfer this solution to a garden sprayer and spray on the trunk and branches.
6. Trunk Injection
Trunk injections are another one of the best DIY oak tree borers treatment options. These injections are used in early spring to kill the larvae of borer beetles. Hiring a professional is highly recommended for this job.
7. Use Insecticide
Apply a cyfluthrin, permethrin, bifenthrin, or carbaryl insecticide to the bark of the trunk, branches, and the tree’s foliage. Perform one spray treatment in spring and a follow-up in midsummer. Make the spray according to the manufacturer’s instructions.
