What is Emerald Ash Borer?
Emerald Ash Borer (EAB) is an invasive pest from Asia that has killed tens of millions of ash trees throughout the United States since it was first discovered in Michigan in 2002. EAB was first detected in Vermont in 2018 and has been spreading through the state ever since. Through a combination of natural spread and human activity, EAB is now found throughout the United States and Canada.
EAB has predominantly targeted green, black, and white ash trees. Depending on the size and health of the tree, an infested tree will typically die in 3-5 years.
Signs & Symptoms
- Adult beetles emerge in late May/early June
- Bark splitting
- S-shaped tunnels beneath the outer bark
- D-shaped exit holes 1/8″ wide on bark surface
- Woodpecker flecking
- Crown dieback
- Leafy offshoots on the lower trunk
Despite the challenges presented by EAB there are steps you can take to protect your ash trees. Black Diamond uses the most advanced products on the market to provide treatment options that are safe for you and the environment. The sooner a tree is treated, the more likely it will survive. Preventative treatment before the tree has visible signs and symptoms is most effective.
