The Pest

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 but cause little damage. 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.


Since its discovery, the EAB has…

  • Killed tens of millions of ash trees in southeastern Michigan alone, with tens of millions more lost in Illinois, Indiana, Kentucky, Minnesota, Missouri, New York, Ohio, Ontario, Pennsylvania, Quebec, Virginia, West Virginia, and Wisconsin.
  • Caused regulatory agencies and the USDA to enforce quarantines and fines to prevent potentially infested ash trees, logs or hardwood firewood from moving out of areas where EAB occurs.
  • Cost municipalities, property owners, nursery operators and forest products industries tens of millions of dollars.



For this treatment, the arborist drills small holes in the base of your ash tree and then plugs the holes with the Arborjet system. The arborist then injects an insecticide called TREE-äge® until the tree has completely absorbed the appropriate amount.



In several intensive studies conducted by MSU and OSU researchers, a single injection of TREE-äge® provided excellent control of Emerald Ash Borer for approximately two years, even under high pest presence.


When to treat

Ash trees may be treated spring through fall and should be treated as soon as possible to prevent damage. An affected ash is still treatable as long as more than half of the tree is not damaged. This may sometimes be difficult to assess, however, because it is not possible to see all internal damage that has been done.
