Emerald ash borerThe emerald ash borer is a beetle that ravages ash trees. It is barely an inch long, but the amount of damage it can do is beyond comprehension. In its larval stage, it rages in the pulp of the wood, making serpentine galleries. Then, equipped with wings, it emerges and attacks the foliage.
This terrible insect comes from Asia. It reached North America almost two decades ago. Unfortunately, it has also established itself in Quebec. It travels from one territory to another on raw wood, including in the trees themselves or in materials or packaging made of this wood species. |

The effects of the emerald ash borer on trees
On average, trees attacked by this pest die in about five years. However, the younger the ash tree, the less time it takes. One year may be sufficient.
It has been mentioned that the larvae burrow into the wood. Over time, these tunnels eventually interfere with the flow of sap, depriving the tree of food. External signs are leaves that turn yellow too soon, bald sections of foliage or peeled bark, etc. These signs progress from top to bottom.
Note that a tree that is half-ruined by the insect is generally suitable to cut down, as it may not be possible to find a remedy. The stump should also be removed as a precaution. However, it is important to do this outside of the beetle's propagating period, which is roughly mid-March to mid-September. Contact our tree service Pierrefonds arborists before you find yourself in an irreparable situation.

Locating the emerald ash borer
When only the larva is active, it would be surprising if there were any visible signs to make you suspect its presence. Therefore, at this stage, the bug is exceedingly difficult to detect. When the insect enters the scene, the signs may become more visible. You can see holes in the shape of a capital letter "D", made by the insects as they leave the tree. Bark is sometimes removed by squirrels or woodpeckers that have come to feed on the larvae. The flying insect nibbles on the leaves. Other signs will also gradually become apparent: sap flowing, shoots invading the trunk, and many others.
On the other hand, the same signs may very well indicate another disease or insect. Knowledge is required to distinguish between the various possible diseases. Our experienced arborists will know how to identify them with accuracy across Montreal.

Identify the emerald ash borer as early as possible
Extremely early intervention is a must with the emerald ash borer (EAB). To make this possible, a simple protocol has been devised: Choose a branch and bark it. If this is done at the right time, i.e., when the larva is at its maximum size (in autumn or winter), the larva can be more easily spotted. However, the signs must be correctly interpreted. Our arborists at Emondage Pierrefonds know all about this. Contact us if you own ash trees and you suspect the presence of the emerald ash borer or damage to your other species.
Prevention is still the best option for the emerald ash borer
The best thing to do is to not plant any ash trees. But they may be on your property long before you or the emerald ash borer arrive, or before you are aware of their existence. Here are a few tips to reduce the risk of having to deal with the beetle. You can plant other species of trees on your property as well. If you heat with wood, try to source it locally, to limit the spread between regions.
The Canadian Food Inspection Agency is responsible for enforcing regulations regarding the transportation of ash wood from unaffected areas to affected areas. The vehicles used as well as ash products (packaging materials, pallets, crates, logs, raw wood, and trees) that may contain the insect are subject to monitoring by the Agency.
