The emerald ash borer has spread to Chelsea and L'Ange-Gardien in Quebec, the Canadian Food Inspection Agency has confirmed.

Movement restrictions — which prohibit the movement of all ash materials including logs, branches and wood chips, and all species of firewood from the affected site — have been put in place, according to a CFIA media release.

Property owners in the affected area have been notified and other regulatory measures will be considered once survey work has been completed.

The presence of EAB has so far been confirmed in five areas in Quebec, and in 27 Ontario counties.

Although it does not pose a risk to human health, it is a highly destructive beetle and has already killed millions of ash trees in Ontario, Quebec and the United States.
