About this Tree Concern
The emerald ash borer has only been in Canada since the summer of 2002 but has had a devastating impact on ash trees in North America. It's estimated that 8 billion North American ash trees are at risk from this beetle. The emerald ash borer is a metallic green beetle that grows up to 14 millimeters. The insect gets its name from its iridescent green back. This insect attacks and kills all species of ash tree. An infested ash tree can die after two to three years but heavily infested trees have been observed to die after only one year of attack.
Emerald ash borer damage can be identified by thinning canopy, branch dieback, bark splitting, zigzag tunnels under the back and D-shaped exit holes that are about 3mm across.
There is significant effort by Canadian and U.S. government to mitigate the economic and environmental impact caused by this beetle.

Remediation
The emerald ash borer is a very aggressive pest. Acting promptly by engaging us is crucial to save the ash tree. In Canada it is regulated not to move ash firewood from zone to zone to prevent the spread of the emerald ash borer eggs and larvae into a new zone or to a pest-free area.
