By now you have heard about Emerald Ash Borer (EAB) but you’re not sure if this is going to affect you.  At this point in time the question is not if, but when this destructive pest will spread further. The key here is that it is spreading as it was first detected in Boulder in 2013 spreading to the Longmont area by 2015.  The next question you are asking is, should I treat my tree(s) now or can I wait? Here are a couple of sites that you can refer to; or, there is even an APP for that! The APP is available for Android or IPhone and can be downloaded in the usual way.

Here are some warning signs for EAB:

  • Thinning of leaves and upper branches and twigs
  • Serpentine tunnels produced by larvae under the bark
  • D-shaped exit holes 1/8-inch wide
  • New sprouts on the lower trunk or lower branches
  • Vertical splits in the bark
  • Increased woodpecker activity

EAB is fatal to all infested Ash trees unless the trees have been chemically treated. We want our clients to be aware that a trunk injection for larger trees (2-year residual), a soil injection for smaller trees (1-year residual) or a soil drench for much smaller trees can still be performed throughout the end of August.  If you would like further information or would like a free quote, please contact us.
