EcoShield Pest Control serves several communities throughout the United States, and for our customers in Chicago and Denver, the emerald ash borer presents serious concerns. The emerald ash borer (EAB) was accidentally introduced to the United States from Asia in 2002, and since then has killed millions of ash trees in North America. Scientists and environmentalists are concerned about the continued spreading because they could have devastating economical and ecological impacts.

When first discovered, information about EAB was scarce, consisting only of two pages of a brief history. Since then, vast amounts of research related to the biology of EAB, management, impacts, and its ecology, has been conducted and shared. The latest reports from September 2013 show EAB present in 21 states across the U.S. and two Canadian provinces. EAB was first discovered in Michigan and likely transferred during the movement of Ash trees and logs.

The EAB is typically a bright, metallic, emerald green color overall. Some species are coppery-red, or bluish-green. The abdomen is a bright metallic red color. The size of the beetle may vary depending on age and location. For detailed descriptions and identification instructions, download the EAB ID Guide.

Treating EAB

Several university researchers, from Ohio State, Purdue, Michigan State, and Colorado State, have banded together and co-written a document for effective treatment of EAB. The focus is on insecticide options for treating Ash trees that is far less costly than tree removal and can even protect trees that have a high density of EAB.

While several insecticide options are available, for greatest effectiveness it is important to ensure the product is applied at the proper rate and time. If EAB has been detected in the vicinity of your home or property, it is important to begin treatment right away. For best results, begin treatment of trees while the trees are relatively healthy. An insecticide will stop damage, but it cannot reverse the damage already caused by the beetle.
