Emerald ash borer (EAB) is an invasive exotic insect that attacks ash trees. Ash trees have no chance of survival if they are infested, unless treated in time. EAB was discovered for the first time in North America in 2002 in the Windsor / Detroit.

Since 2009, the EAB has wreaked havoc in several Canadian cities, including Ottawa and Montreal. It’s also a threat to a number of cities such as Quebec, Sherbrooke and Trois-Rivières. If you have ash trees in an infested area, you have two choices: cut it down or use a registered insecticide such as TreeAzinTM.

Here are some signs of infestation of the EAB:

Treatment of EAB

It is possible to treat healthy ash trees in an area at risk of infestation or even some trees already infested with the insecticide TreeAzinTM. If you have an infested tree, contact us quickly to determine if it is still possible to treat it. The faster you act, the greater the chances of saving your trees are. TreeAzinTM is a systemic insecticide injected at the base of trees that provides protection for up to 2 years in the treated trees.

The cost of TreeAzinTM treatment depends on the size of the tree, measured at mid-chest height or 1.3m above ground level.

The application of TreeAzinTM is done between June and August 31st.
