Protecting Ash Trees: How to Combat the Emerald Ash Borer Infestation

Understanding the Threat

The Emerald Ash Borer (EAB) is an invasive beetle that has caused widespread destruction of ash trees across North America—and the West Island, Saint-Lazare, Vaudreuil, and Hudson are no exception. This small green beetle targets ash trees, boring into the bark to lay its eggs. When the larvae hatch, they feed on the tree's vital inner bark, cutting off the flow of water and nutrients and ultimately killing the tree.

Local Impact in West Island & Surrounding Areas

Early detection is crucial. Look out for:

• Thinning or dying branches in the upper canopy

• D-shaped exit holes in the bark

• Bark splitting or increased woodpecker activity

• Leaf loss or premature autumn coloration

If you notice any of these signs on your property, it may be time for a professional evaluation.

What You Can Do

Municipalities like Pointe-Claire, Beaconsfield, Kirkland, and Saint-Lazare have seen significant ash tree loss due to EAB. Many homeowners are unaware of the infestation until it’s too late. Dead or dying ash trees also pose safety risks, especially in residential and high-traffic areas.

• Assessment: Have a certified arborist assess your ash trees.

• Treatment: In early stages, trees can sometimes be treated with trunk-injected insecticides.

• Removal: Severely infested or dead trees should be professionally removed to prevent safety hazards and slow the spread.

• Replacement: Consider replanting with non-ash, native tree species.
