What is the emerald ash borer?
The emerald ash borer is a destructive beetle native to Asia, considered an exotic insect pest in Quebec. This insect pest lays its eggs under the bark of ash trees, where its larvae dig serpentine galleries (or larval galleries) that block the flow of sap, causing the tree’s gradual death. To slow its spread, municipalities such as the City of Montreal impose regulated zones and sometimes require a tree felling certificate.

Recognizing the Emerald Ash Borer
It’s important to look for at least two signs or symptoms when trying to determine if the Emerald Ash Borer is present in an ash tree, as some symptoms can resemble those caused by other pests and diseases.
D-Shaped Exit Holes
When adults emerge from under the bark, they create a D-shaped exit hole about 1/8 inch in diameter.
Foliage Loss
Crown dieback is caused by larval feeding, which disrupts nutrient and water supply to the upper canopy. Trees typically experience leaf thinning at the top of the tree within one to three years of infestation, followed by the death of some branches and the tree.
Abnormal Trunk Growth
When trees are stressed or diseased, they attempt to grow new branches and leaves where they still can. Trees may develop new growth at the base and on the trunk, often just below the larval feeding area.
Bark Cracks
Vertical cracks in the bark are caused by the development of calluses around larval galleries. These galleries are often visible under cracks in the bark.
Emerald Ash Borer Treatment
To effectively combat the emerald ash borer, Arbo Rive Nord recommends treatment with TreeAzin, an approved botanical insecticide injected directly into the tree. This TreeAzin application, performed by a certified arborist, complies with the standards of the City of Montreal and regulated areas. To avoid the accumulation of dead wood or the issuance of a felling certificate, early intervention is essential. Call Arbo Rive Nord for safe, effective ash tree treatment that complies with local requirements.
Protecting Your Trees from the Emerald Ash Borer
To protect your ash trees from the Emerald Ash Borer, key strategies include:
Consulting an Arborist
It is essential to consult a certified arborist like Arbo Rive Nord. These professionals have the expertise to assess the health of your trees, apply appropriate treatments, and comply with applicable standards, particularly in regulated areas such as the City of Montreal. They will also guide you through the process of obtaining tree removal certification if necessary.
Using a treatment
Treatment with TreeAzin, a biological botanical insecticide, is an effective solution for protecting healthy ash trees. TreeAzin is applied by trunk injection, a process that must be performed by a specialist to ensure proper and effective treatment. Other systemic insecticides such as emamectin benzoate or dinotefuran are also used. The treatment must be repeated annually to maintain protection.
Replace with other species
If your ash trees are severely infested with this repellent insect, it is recommended to replace them with other tree species adapted to the local tree flora. This strategy helps diversify your environment and reduce the risks associated with the spread of this exotic insect pest.
Management of infested trees
Prevent the spread: Do not move firewood from regulated areas, as the emerald ash borer spreads easily via this vector. Use local wood and properly dispose of residues by burning them on site or leaving them for future users.
Remove and destroy infested trees: To limit the spread, severely infested trees should be felled and their wood destroyed by burning or burial. Also consider treating or removing regrowth at stumps to prevent re-infestation.
