Emerald Ash Borer

Emerald Ash Borer, Agrilus planipennis (Fairmaire)

The Emerald Ash Borer (EAB) is an invasive green beetle that is killing Ash trees in this part of Ontario.

Infestations now exist across much of southern Ontario, from Lambton County north to Grey County and east to Renfrew County and Ottawa, among other places.

Millions of Ash trees have been killed in North Amercia by this highly destructive beetle.

This insect attacks and kills all Ash species (except Mountain Ash, which is a different tree species, despite its name).

To help prevent the spread of the invasive species, the movement of Ash logs and firewood out of regulated areas is restricted.

Don't move firewood.

Report any detections outside of regulated areas to one of the CFIA's offices. 

Invasive refers to a species that has moved outside of its native habitat and threatens the new environment, economy, or society by disrupting local ecosystems.

This invasive insect was first discovered in Ontario in 2002.

Federal regulatory controls restrict the transport of infested Ash, including firewood, from infested to non-infested areas.

The Emerald Ash Borer (EAB) was originally discovered in Windsor, Ontario in 2002.

Since this initial find, the insect has travelled by natural spread and through the movement of Ash products to a number of jurisdictions within the Province of Ontario.

The Canadian Food Inspection Agency (CFIA) is the lead agency on the regulation and control of all exotic pests, such as the Emerald Ash Borer, introduced into Canada.

The CFIA currently has imposed six regulated areas in Ontario for the Emerald Ash Borer, within which the removal of Ash materials and all species of firewood is prohibited.

The Ontario Ministry of Natural Resources and Forestry (OMNRF) partners with the CFIA and the Canadian Forest Service (CFS), through aerial reconnaissance, ground surveys, research and trapping programs to monitor the extent of damage caused by the Emerald Ash Borer in Ontario.
