Protecting Your Trees from the Emerald Ash Borer

For local ash trees, the arrival of a devastating pest in the Susquehanna Valley is very bad news. The Emerald Ash Borer has been an unwelcome guest in the United States for several years, but until recently it had not been found in our area. Unfortunately, all that’s changed and the beautiful ash trees that shade our neighborhoods and line our trees are now in danger.

Recently, various media have shared the ramifications of Emerald Ash Borers on local plants. In their larval stage, these beetles bore into trees causing thinning of the tree canopy and branch dieback. While it is true that in most cases infested trees die after three to four years, residents should not give up home for their trees.

Significant research has and is currently being conducted to yield treatments options. In Michigan, where its’s suspected that the borer has been present for over five years, a study by Michigan State University has proven that there are valid treatments. Tests indicate that although severely infested trees typically cannot be saved, attacks on healthy tress can be prevented.

Periodic inspections, prompt removal of infested trees and annual treatments with the appropriate insecticides are all part of a successful loss prevention plan. Each tree is different and should be evaluated on a case-by-case basis.
