In previous blog posts, we’ve explained the ins and outs of the emerald ash borer. This common pest in Northern Colorado may not seem like a nuisance at first glance. However, the small green jewel beetle certainly packs a punch. Native to northeastern Asia, the emerald ash borer feeds on ash trees. What makes it so dangerous is that there are no predators to keep its population in control since it’s not native to the area. So what exactly should you be looking for when it comes to identifying the emerald ash borer? Keep reading to learn more.

Here are some of the more common signs of an EAB infestation:

  1. Crown dieback – After several years of EAB larval feeding, dieback of the upper and outer crown begins to take place. This activity disrupts nutrient and water flow to the upper canopy, resulting in leaf loss. Not only that, but leaves at the top of the tree may be thin and discolored.
  2. Bark splits – Take a close look at the bark of your ash tree. Do you notice vertical splits at all? This may be caused by callus tissue that develops around EAB larval galleries. Not surprisingly, bark splits often spell disaster for ash trees.
  3. Epicormic sprouting – Trees have a pretty amazing self-healing ability. When sick or stressed, they will try to grow new branches and leaves wherever possible. With EAB, trees may have new growth at the base of three and on the tunk. This occurs just below where the larvae are feeding for the most part.
  4. Woodpecker feeding – Woodpeckers eat EAB larvae that are under the bark. That said, the damage has been done. Note that if there happens to be a large number of larvae under the bark, the woodpecker damage can make it look like strips have been pulled off the tree.
  5. D-shaped emergence holes and S-shaped larval galleries – As EAB adults emerge from under the bark, they create a D-shaped emergence hole that’s about ⅛ inch in diameter. Something else to look for is when larvae feed under the bark and wind back and forth, they create S-shaped larval galleries.
