Emerald Ash Borere adult red belly.jpgThe Emerald Ash Borer (EAB) is a small (10 - 13 mm) shiny emerald green beetle that kills ash trees. Ash is found throughout forests and woodlots in Ontario and is commonly used as a street or landscape tree. EAB is an invasive pest, native to Asia and was first noticed in North America in 2002.
