Emerald Ash Borer Photos

Serpentine-shaped tunnels on an ash tree created by Emerald Ash Borer on a residential property near Whitehouse. The tunnels in the cambium, just beneath the bark, effectively cut off food and water from the tree.

Signs of the Emerald Ash Borer on a tree in Lucas County near Whitehouse include die-back on the upper third of the tree, D-shaped exit holes in the bark where adults emerge, vertical splits in the bark, and distinct serpentine-shaped tunnels beneath the bark in the cambium.

When the Emerald Ash Borer emerges from its larvae stage as an adult, it creates d-shaped exit holes in its host tree's bark.

 

Adults are dark metallic green in color, 1/2 inch in length and 1/16 inch wide, and are present only from mid May until late July. Larvae are creamy white in color.

Tree cutters work to cut large ash trees to eradicate EAB in isolated infestations in Columbus, Hicksville, and Rossford.
A tree cutter scales a large ash tree in a wooded residential area northeast of Columbus to remove the ash trees that could act as hosts for EAB this spring.
Thousands of trees have been removed to protect billions more ash trees from becoming infested. The felled trees will be chipped and burned to destroy the beetle.
A tree chipping machine turns ash trees into sawdust to effectively eliminate EAB.
