5 Warning Signs Your Ash Tree Has Emerald Ash Borer (EAB)

Emerald Ash Borer (EAB) is a destructive pest that has decimated ash tree populations across North America. These tiny green beetles might seem harmless, but their larvae wreak havoc beneath the bark, disrupting the tree’s ability to transport water and nutrients. Early detection is crucial for successful treatment and preserving your ash trees.

Is EAB Invading Your Ash Tree?

Here are 5 key warning signs to watch out for:

1. Canopy Thinning:

One of the first noticeable signs of EAB infestation is thinning of the tree’s canopy. Leaves may appear smaller, less vibrant, and sparse, especially in the upper crown. This is due to the larvae disrupting the flow of nutrients.

2. Epicormic Shoots:

As the tree struggles to survive, it may produce new shoots from the trunk or branches, known as epicormic shoots. These shoots are a desperate attempt to compensate for the damage caused by the EAB larvae.

3. D-Shaped Exit Holes:

Adult EAB beetles emerge from the tree, leaving behind distinctive D-shaped exit holes in the bark. These holes are about 1/8 inch in diameter and are a telltale sign of infestation.

4. Random Browning Limbs:

EAB can cause limbs in the canopy to completely die-back, which leads to fallen and broken limbs.

5. Trunk Bleeding:

Once EAB become adults in their life cycle they will begin to borer out of the tree’s bark. The ash trees will begin to show sap dripping from that same area.

Don’t Wait, Take Action!

If you suspect your ash tree is infested with EAB, it’s crucial to contact a professional arborist immediately. Early intervention is key to successful treatment and can significantly increase the chances of saving your tree.

Treatment Options: A Deeper Dive

Protecting your ash trees from EAB often involves a multi-faceted approach. Here’s a closer look at the available options:

  • Insecticides: Several types of insecticides can be effective against EAB.
  • Soil Injections: Applied around the base of the tree, these insecticides are absorbed by the roots and transported throughout the tree, killing EAB larvae. They are generally effective for one to two years.
  • Trunk Injections: Injected directly into the tree’s trunk, these insecticides provide a more targeted approach and offer quicker protection. They typically need to be reapplied every one to two years.
  • Bark Sprays: Applied to the bark of the tree, these insecticides target adult beetles and prevent them from laying eggs. They are generally less effective than soil or trunk injections and require more frequent applications.
  • Tree Removal: Sadly, in advanced cases where the tree is severely damaged and declining rapidly, removal may be the only option. This prevents the spread of EAB to other healthy ash trees in the area and eliminates the safety hazard of a dying tree.

Choosing the Right Treatment:

The best treatment option for your ash tree depends on several factors, including:

  • The tree’s health and size: Healthy trees are more likely to respond well to treatment.
  • The level of infestation: Early detection allows for more effective treatment.
  • Your budget and long-term goals: Different treatments have varying costs and lifespans.
