Emerald Ash Borer

The Emerald Ash Borer (EAB) is an invasive insect originating from Asia.  It was first discovered in North America in the Detroit and Windsor area in 2002.  The insect attacks and kills ash trees (only true ash or fraxinusspecies, it does not affect Mountain-Ash or sorbus species).  Since its introduction it has been spreading throughout southern and central Ontario, Quebec and many states within the US causing the death of millions of trees.

The pest was first discovered in southern Simcoe County in 2013.  By 2016 it has been found in over half of the local municipalities within the County.  LEARN MORE >>
