What are killing my Ash Trees?

Emerald ash borer (EAB), Agrilus planipennis Fairmaire, is an exotic beetle that was discovered in southeastern Michigan near Detroit in the summer of 2002. The adult beetles nibble on ash foliage and can cause major damage to the ash trees growth. The larvae (the immature stage) feed on the inner bark of ash trees, disrupting the tree's ability to transport water and nutrients. Emerald ash borer probably arrived in the United States on solid wood packing material carried in cargo ships or airplanes originating in its native Asia. See a map where Emerald Ash Borers are as of September 1, 2016

What are Emerald Ash Borers?

  • Adult Beetles are metallic green and about 1/2-inch long

  • It attacks only ash trees (Fraxinus spp.)

  • Adults leave a D-shaped exit hole in the bark when they emerge in spring.

  • Woodpeckers like EAB larvae; heavy woodpecker damage on ash trees may be a sign of infestation.

  • Firewood cannot be moved in many areas because of the EAB quarantine.

  • It probably came from Asia in wood packing material.
