It's #EABAwarenessWeek: How to Protect Your Trees from EAB Infestation

It’s the lean, mean, green pest that continues to infect and kill ash trees throughout the U.S. and Canada. Find out how close you are to emerald ash borer infestations and what you can do about this pest.

Emerald ash borer (EAB) has destroyed millions of ash trees and devastated the tree canopy cover throughout portions of North America. EAB was identified in North America in Michigan in 2002, but it likely first arrived in wood cargo crates from Asia as much as a decade earlier.

Here’s how you can manage EAB:

1. Recognize signs of EAB:

First, you must correctly identify and understand the source of damage. EAB is a metallic, green-colored beetle, about ½-inch long and a 1/8-inch wide.

Look out for these signs of damage on your trees:

  • Thin, 2- to 5-inch vertical slits in bark
  • 1/8-inch, D-shaped holes in bark
  • S-shaped tunnels beneath bark
  • A sparse, thin canopy near the top of the tree
  • Unusual sprouting of branches at the base of the tree or on the trunk

2. Find out how close EAB is to you:

Locate where you are on the United States Department of Agriculture Cooperative Emerald Ash Borer Project map and see if EAB is spreading near you.

3. There is hope! How to treat EAB:

Employees at the Davey Institute continue studying EAB to better protect trees from this deadly pest. Watch Davey Institute Director of Technical Services, Jim Zwack, talk about EAB and treatment options here:

4. What your city should do if EAB arrives:

Cities that are expected to be infected by EAB should have a plan in place. Weigh your options: treatment vs. removal. When planting new trees, plant a variety of species, so any particular pest or disease is less likely to wipe out the entire urban forest canopy.

Cities with EAB plans in place:

  • Detroit Davey Employees Preserve a Treasured, EAB-Infested Ash Tree

    We all have one tree in our yard – or from our childhood home – that holds the most special place in our heart. The one you planted right when you moved in or the big, stately oak your children used to climb. The one tree you can’t help but smile when you see.

    For Cathy P. in Detroit, it was the tree her late father-in-law had helped her husband plant 20 years ago. But it was time to say goodbye to the tree last fall when emerald ash borer damage threatened its survival. Read below how Davey was able to help keep the memory of her tree alive – even after its demise.
