Emerald Ash Borer in sick ash trees

 


Emerald Ash Borer

A destructive metallic green beetle, emerald ash borers (EAB) invade and kill all types of ash trees, Fraxinus species. Green, white, Autumn Purple, and all others are susceptible. EAB kills trees in 2 to 4 years after initial infection. It has killed millions of trees in the Midwest and is slowly spreading across the country.

 

Damage

An EAB infected tree has a thin or dying crown and erratic growth along the trunk of the tree. It is often a popular site for woodpecker feeding as the bird is harvesting the beetles in the bark. Finally upon close inspection of the trunk you might see unique "D" shaped holes. This is where the beetle exited the tree.

Control

There are a host of preventive treatments available for trees within 15 to 20 miles of other infected trees. Treatment outside this risk zone is not prudent. Keep in mind that treatments must be done each year for the life of the tree and will not be effective against other injuries that may compromise the tree's health.
