How To Identify Emerald Ash Borer Damage

It’s been five years since the Emerald Ash Borer was first discovered in Colorado. This beetle continues to get the attention of homeowners and arborists alike and for good reason. In this post, we thought it would be good to review the signs and symptoms of an EAB attack.

Let’s look at some of the most common ones:

  1. Crown dieback – After several years of EAB larval feeding, dieback of the upper and outer crown becomes noticeable. You might start to notice dead branches through the canopy, beginning at the top. Leaf loss is also common because larval feeding disrupts water and nutrient flow to the upper canopy. Thin, discolored leaves at the top of the tree can also be an indicator of EAB.
  2. Bark splits – Those vertical splits in the bark shouldn’t be ignored. These are caused by callus tissue that develops around larval galleries. If you look close enough, you should be able to see larval galleries beneath the bark splits.
  3. Woodpecker feeding – Fun fact: woodpeckers eat EAB larvae that are under the bark. Now, this usually only happens higher in the tree where the beetle prefers to attack first. Do you notice that strips of bark have been pulled off the tree? This could be damage from woodpecker feeding.
  4. EAB beetles – Maybe you’re wondering, “What does an Emerald Ash Borer look like?” Well, an adult beetle is metallic green and about the size of one grain of cooked rice. Adult EAB beetles have a flat back and a rounded underside.
  5. Larvae – EAB larvae are found beneath the bark. They are cream-colored, slightly flattened, and have pincher-like appendages at the end of their abdomen. EAB larvae grow to about one and a half inches.
