Emerald Ash Borer (EAB) continues to devastate ash trees in cities throughout the Midwest and was reported in Goodhue County last year. The small metallic green insect lays eggs in the tree. The larval form then chews its way through the interior of the tree below the bark slowly cutting off the supply of water and nutrients to the upper portions of the tree resulting in its decline.

EAB affects only ash trees and there are steps you can take to help save ash trees on your property. Both homeowner and commercially applied treatments are available if you choose to treat your ash trees. Sargent’s recommends using Optrol Insect Control for prevention of EAB. Our staff can help you choose the right product and determine the correct amount needed to treat your trees. The treatment is easy to apply and done once a year in the spring or early summer. If you think you may have a tree infected with EAB, visit the Minnesota Department of Agriculture Emerald Ash Borer website for more information.
