Threat of Emerald Ash Borers to Area Trees

Jun 28, 2017 06:23AM
All ash trees in Montgomery County are at risk of long term damage or death caused by the Emerald Ash Borer (EAB). This beetle was brought to the United States from Asia and has spread across the greater D.C. area. As adults, these beetles do not cause significant damage to trees. However, their larvae threaten all species of ash trees by feeding on the tissue between the bark and wood.

Unless residents are proactive in protecting ash trees from damage caused by EAB, scientists predict that nearly all ash trees in Montgomery County, alone, will die within the next 10 years. Treatment is effective and treating ash trees in the early stages of EAB infestation can minimize damage, allow for recovery and prolong their life.

It is possible to do advance treatment if trees are not yet showing signs of EAB-related damage. If trees have an early stage EAB infection, treatment is the best way to save the tree. However, if trees have an advance EAB infection or if the tree is dead, a tree expert can help determine if the tree is hazardous and at risk of falling.  It is also important to prevent the EAB from spreading to other trees.
