Be on the lookout for Emerald Ash Borer

Emerald ash borer has not yet been found in North Carolina. However, it is found in Tennessee and Virginia so it is just a matter of time before it arrives here or in your home state.  The reason I bring it up now is that it is peak adult activity (based on degree day estimates) so they may be more noticeable now than other times of year.  Adults will be emerging from D-shaped holes in ash trees. If you notice ash trees that seem to be in decline look for these exit holes and frass around the base of the tree.  Early detection of emerald ash borer is critical in trying to reduce the economic impact and protect trees.  The most comprehensive and up-to-date information on emerald ash borer can be found at http://www.emeraldashborer.info/
