Besides serpentine galleries, other symptoms of an Emerald Ash Borer infestation are the tops of ash trees dying out, large D-shaped exit holes in trees and woodpecker damage to a tree.
“All varieties of ash are attacked by the Emerald Ash Borer,” Shour said. It’s the odor of the ash tree that attracts the Emerald Ash Borer, he added.
Homeowners can help protect their ash trees by having them treated with chemicals called neonicotinoids. They can be injected into the tree, injected into the soil around the tree, drenched in the soil around the tree or sprayed onto the tree, Shour said. The chemicals should be applied every year in mid-April to mid-May. There is another chemical called “Tree-Age” that can be injected into the tree that is good for two years, he added.
