Protect Your Trees

If you are a homeowner in Oakville and you have any Ash trees on your property, this is the last week to have your trees inspected and treated for Emerald Ash Borer. The Town of Oakville said the deadline to have trees treated with the bio-insecticide TreeAzin this year is Saturday, Aug. 31. Dead trees on your property can become a safety hazard and violate the Property Standards Bylaw, so it is important to get them taken care of before it’s too late.

Emerald Ash Borer (EAB) is an invasive Asian insect that eats the soft wood under a tree's bark, which prevents the tree from moving water and nutrients from roots to leaves. This pest usually kills a healthy tree within 3 years. Fortunately, Oakville has one of the most aggressive and successful EAB eradication plans in the country.

The Town of Oakville has said the Ash Tree situation in Oakville is even more urgent this year as urban forestry professionals are seeing a vast decline in healthy ash trees. When trees are left untreated, it becomes necessary to remove them completely. Town Staff are warning that this may be the last summer that trees can be saved by an effective treatment program before it’s too late.

To date, the Town has treated about 6,000 public ash trees on streets and in parks. However, about 80% of Oakville’s treatable ash tree canopy is on private property, so it is important for individual homeowners to contact a quality service provider who can inspect the trees on your property and give you a quote for treatment or removal. Protecting and preserving your trees will protect the value of your home and draw buyers who are looking for homes with mature trees.

Check your trees for the following signs of EAB infestation:

  • The leaves in the top third of the ash begin to die back
  • New, thin branches begin to grow from the low trunk or roots
  • There are white lines or canals under the bark
  • The bark on the tree begins to split
  • There are D-shaped exit holes in the bark formed by adult beetles exiting the tree
  • There is increased woodpecker activity on the tree

The Town launched the Oakville Canopy Club in 2011 in response to EAB infestations as a public education program. For more information about preserving your Ash trees, treating infested trees and protecting the local fauna, visit
