Question:

Should I treat my ash trees to protect them from emerald ash borers?

Answer:

Insecticide treatments are available to protect ash trees from the emerald ash borer.   However, treatments should be undertaken only when necessary to prevent excessive and needless use of insecticides. 

Insecticide treatments to control emerald ash borers should not undertaken unless you have healthy ash trees and live within 15 miles of a confirmed emerald ash borer infestation.
