Emerald Ash Borer and Treatment

Emerald Ash Borers Are Killing Ash Trees across the Philadelphia Region

Emerald Ash Borers are spreading rapidly. This 100% fatal pest is forcing homeowners to choose between treatment or tree removal. If you have Ash trees you love, you need to take action now.

Unfortunately, anyone with an Ash tree faces a difficult decision. Protect the Ash tree from Emerald Ash Borer with treatment or let it die and remove it. Without treatment, Ash Trees with Emerald Ash Borer die within 1-3 years. By the time you see visible decline, Emerald Ash Borer has already done significant internal damage to the tree. That’s why, it’s critical to treat now before damage is beyond repair. Check out our Emerald Ash Borer Fact Sheet for more information.

Here's How to Protect Your Ash trees from Emerald Ash Borer

  1. Early detection: Have your Giroud ISA Certified Arborist evaluate your property for Ash trees and recommend the best action.
  2. Treat high value Ash trees with a systemic trunk injection every two years. In performance tests, Michigan State researchers found that systemic trunk injections of TREE-age® with Emamectin Benzoate (Em Ben) applied every two years, achieved the best results. The chart below shows the number of Emerald Ash Borer found two years after different treatment options were performed.

Emerald Ash Borer Treatment Research Results
  1. Regular Pruning Remove deadwood and prune to promote healthy growth in combination with treatment.
  2. Tree Removal: When untreated Ash trees become unsafe or die, have them removed. This will always keep your property safe and beautiful.

Other Emerald Ash Treatment Options

While systemic trunk injection is without a doubt the best treatment to combat Emerald Ash Borers, there are other options:

    1. Soil Injection/Soil Drench with Imidacloprid: EAB control has been inconsistent. Experience and research indicate that this treatment is most effective on smaller trees. The treatment must be applied annually in mid-late Spring or mid-Fall.
    2. Basal Trunk Sprays with Dinotefuran: Control was variable in research trials. The treatment reduced EAB larval density by approximately 30 percent to 60 percent compared to heavily infested untreated trees. The treatment is effective for one year.
    3. Topical Cover Sprays: Provides good control, especially when the insecticides were applied in late May and again in early July when the adult Borer are feeding on the leaves.
