How much does it cost to treat a tree for emerald ash borer?
An average cost of treatment is approximately $11.00 per DBH. Dose rate of formulation and cost are determined by your tree’s diameter at breast height (DBH). Starting at 4½’ up from the base of the tree, measure the circumference of the tree’s trunk in inches with a measuring tape.
