About Emerald Ash Borer

"Emerald ash borer (Agrilus planipennis; EAB) is an insect native to Asia. It was introduced into North America sometime during the 1990s, probably via ash wood pallets or wood packing material. Since its initial discovery in southeastern Michigan in 2002, this insect has killed millions of ash trees (Fraxinus spp.) throughout the central and northeastern United States and Canada.

EAB is now considered the most destructive tree insect pest ever to be introduced into North America. An infestation was detected in Colorado in the city of Boulder in September 2013. Approximately 15 percent of the trees in Colorado's urban forests are ash, making this insect a major threat to urban forests statewide." (Colorado State University) 

Symptoms of Emerald Ash Borer include:

  • Uppermost leaves and branches of the tree are sparse

  • Vertical fissures in the bark, possibly revealing S-shaped channels below

  • Enhanced woodpecker activity

  • Late in the summer, the tips of the branches develop tiny leaves
