The Emerald Ash Borer has been found in Colorado. With it’s arrival, many of our urban Ash Trees are threatened by this pest. Early detection of it’s presence is crucial to planning and carrying out control in our community.
Visual surveys of checking trees can be helpful in identifying infected trees, however often, signs are not visible until the trees have been infected for 2 years or longer, giving the bugs plenty of time to increase their numbers.
The best method for early detection is through branch sampling, which is a highly effective method for finding EAB populations before outward signs or symptoms become apparent.
Up to 74% of infested trees, even those that are not showing symptoms, can be found using this simple technique.
Here’s how to do it: You’re looking for larvae under the bark, so plan a branch sample between September and May, then if you can, wait until after October, when the larvae are big, and it’s easy to see the galleries.
