These insects cut off the flow and water and nutrients by feeding underneath the bark of the trees. All ash trees are susceptible, and if a tree has become infested with EAB, mortality will result, usually within 2-3 years. Healthy trees may be treated with TreeAzin™, the only product registered for use in Canada against EAB that in some cases may be able to slow or prevent infestation in individual trees.
We encourage owners of ash trees to plant new trees to replace those that have been or will be lost due to infestation. LEAF makes the replanting process easy by providing on-site arborist advice to help you select the right EAB-resistant tree for your yard at a subsidized price.
