Emerald ash borer (EAB) is one small pest that has caused a lot of damage. Since the bug’s debut in the USA in 2002, our Davey Institute scientists have been researching the best way to control emerald ash borer. EAB has been detected in 30 states. For an updated list, visit the USDA.
Our goal is and has always been to save your ash trees! EAB can be treated in some cases, but the key is to prevent EAB from affecting your ash trees.
Once you have contacted Davey for a consultation, an arborist will evaluate the threat in your area and your ash trees. Our arborists will recommend the best course of action for your unique property. There are four types of EAB treatment options: soil injection, trunk injection, bark spray and canopy spray.
Emerald Ash Borer Treatment Options
The most common EAB treatments are soil injections and trunk injections. Both deliver the product right into the tree's tissue, which is then evenly dispersed throughout the canopy. The injections target the larvae tunneling in the tree, which stops the most destructive phase of this insect.
Canopy sprays are also used occasionally, which help prevent adult borers from feeding and laying eggs. Systemic applications help limit environmental exposure. However, EAB treatment plans vary based on how many trees you have and the type of treatment needed.
If you know EAB is in your area, or a region near you, contact your local arborist immediately for a consultation and prevention plan.
