How to Detect Emerald Ash Borer Infestation

Introduction

Welcome to The Tree Doctor's guide on how to detect an Emerald Ash Borer infestation. As a leading authority in tree care, Cutting Hedge Services understands the importance of early detection and prevention when it comes to this destructive pest. In this comprehensive guide, you will learn about the signs and symptoms of an Emerald Ash Borer infestation and what steps you can take to address it promptly.

What is the Emerald Ash Borer?

The Emerald Ash Borer (Agrilus planipennis) is an invasive beetle species native to Asia. It was first discovered in North America in 2002 and has since become a significant threat to ash trees across the continent. The larval stage of this beetle feeds on the inner bark of ash trees, disrupting the tree's ability to transport water and nutrients, eventually leading to its decline and death.

Signs and Symptoms

Early detection of Emerald Ash Borer infestation is crucial for effective management. Below are some common signs and symptoms to look out for:

1. Canopy Dieback

One of the early indicators of Emerald Ash Borer infestation is canopy dieback. If you notice a significant thinning or loss of leaves in the upper branches of your ash tree, it may be a sign of infestation. This dieback typically occurs from the top of the tree downwards.

2. S-Shaped Serpentine Galleries

When Emerald Ash Borers feed on the inner bark, they create distinctive S-shaped serpentine galleries. These galleries can be seen underneath the bark and are a tell-tale sign of an infestation. Look for these galleries in the main trunk and larger branches of the ash tree.

3. D-shaped Exit Holes

Emerald Ash Borers exit the tree once they reach the adult stage, leaving behind characteristic D-shaped exit holes. These holes are roughly 1/8 inch in diameter and can be found on the branches, trunk, and bark of an infested ash tree. Keep an eye out for these holes as they are definitive evidence of an Emerald Ash Borer infestation.

4. Suckering

As an ash tree tries to compensate for the damage caused by the Emerald Ash Borers, it may produce new shoots or suckers from the base or lower trunk. These suckers are an attempt by the tree to generate new growth above the damaged areas. However, they are often weaker and more susceptible to disease.

5. Woodpecker Activity

Woodpeckers are natural predators of Emerald Ash Borers and are attracted to infested trees. If you observe an increased presence of woodpeckers around your ash tree, it could indicate an infestation. Woodpeckers feed on the larvae present beneath the bark and can cause additional damage to the tree.

Prevention and Management

Preventing Emerald Ash Borer infestation and managing it effectively requires a multi-faceted approach. Here are some strategies that can help:

1. Regular Inspections

Inspect your ash trees regularly for signs of Emerald Ash Borer infestation. By catching the problem early, you can take the necessary steps to mitigate the damage and save your trees. It's important to be proactive and not wait for obvious symptoms to appear.

2. Implement Tree Treatments

Applying targeted insecticides can help protect your ash trees from Emerald Ash Borer infestation. Consult with a professional tree care expert, like The Tree Doctor, to determine the most appropriate treatment options for your specific situation.

3. Quarantine and Control Measures

If you suspect an Emerald Ash Borer infestation, it is crucial to prevent the spread of this destructive pest. Avoid moving firewood or untreated ash wood products from infested areas. Contact your local forestry department or a certified arborist for assistance in implementing control measures.

4. Consider Tree Removal

In severe cases where the infestation has already caused extensive damage or the tree poses a safety risk, tree removal may be necessary. Professional tree care companies, like Cutting Hedge Services, can safely remove and dispose of infested trees following industry best practices.
