Combatting the Emerald Ash Borer

The Emerald Ash Borer (EAB) simply gnaws its way under the bark of ash tree (all of the Frazinus species), until the tree is dead.     In Ottawa the ash trees are more than 20% of our total tree canopy.

As elaborated at   the EAB   can be controlled by having licensed professionals inject TreeAzin into the tree into its base anytime from June through august.      It is recommended that the ash trees be treated before you see damage because the tree is best able to take up the TreeAzin while it is healthy.    

The tree may need to be treated every two years for as many as three or four times.     Tests suggest that three or four applications will provide permanent control of the EAB

For an ash tree on private land, it is recommended that you get a professional opinion from  pre-approved professionals   as listed at the bottom that page

When it comes to trees on city of Ottawa property, contact 311 and obtain a file number of your report for tracing purposes.    Because there are so many ash trees here in Ottawa, you could even consider paying for the treatment of a City owned tree with the City’s  approval.
