Emerald Ash Borer

Treating for Emerald Ash Borer in Southern Ontario

The Emerald Ash Borer (EAB) is a small, slender metallic green beetle approximately 8.5 to 13 mm long. Originally from Asia, this invasive pest has no natural predators here in North America and threatens all species of ash trees in Canada and the United States. The EAB has killed millions of ash trees in Southern and Eastern Ontario since it’s 2002 discovery in the Windsor, ON area.

EAB populations have been confirmed throughout Treesape’s service area.  Sadly, we have been removing infected trees and dying trees throughout Peterborough and the Kawartha Lakes region since 2014.  Fortunately, there is a treatment option for your beloved backyard trees or specimen tree in your community…

“I have an Ash tree, what should I do?”

First, confirm that the tree you are concerned about is, in fact, a true Ash tree.

Emerald Ash Borer (EAB) only attacks true Ash trees (Fraxinus spp.)

  • Medium to large tree
  • Compound leaves, typically 7-9 leaflets
  • Paddle-shaped seeds

Mountain Ash tree (Sorbus spp.) are NOT true Ash trees.

  • Small trees or bushes
  • Compound leaves, typically 13-17 leaflets
  • Clusters of red/orange berries in the fall

For further assistance with ash ID visit Leafsnap and search “Fraxinus”


Next, determine the size of your Ash tree.  Measure the diameter of your tree at a height of 4.5 feet from the ground.

Finally, send your tree details to EAB@treescapecanada.ca and we will provide a free estimate to protect your tree for 2 years with a TreeAzin™ injection.


“What is TreeAzin™?”

TreeAzin™ is an effective remedial or preventative measure in combating EAB.  It is a Bio-pesticide derived from Neem Tree extracts.  Once injected under a tree’s bark, TreeAzin™ moves through the tree killing EAB larvae that are feeding on the tree’s tissues.  It also effectively reduces the fertility and egg viability of feeding adult females.
