About emerald ash borer

Emerald Ash Borer (EAB) is an exotic, invasive, wood-boring insect that infests and kills native North American ash trees, both in forests and landscape plantings. Just like chestnut blight and Dutch elm disease before it, EAB is capable of eliminating an entire tree species from forests and cities. This makes it one of the most serious environmental threats now facing North American forests.

This beetle is native to eastern Russia and northeastern Asia, where it feeds on several species of ash. It was probably imported into Michigan via infested ash crating or pallets at least 15 to 20 years ago.

EAB was unknown in North America until June 2002, when it was discovered killing ash trees in southeast Michigan and neighboring Windsor, Ontario. It has since spread to 20 states and the Province of Quebec and has killed tens of millions of ash trees.
