Update on Emerald Ash Borer (2016)

We continue to keep you updated on the arrival of Emerald Ash Borer (EAB) into our area.  Here’s the update on Emerald Ash Borer for 2016:

  • While Pennsylvania has been dealing with EAB for several years, New Jersey will start seeing, first-hand, the devastation that it brings in 2016.  Native to Asia, Emerald Ash Borer was first discovered in NJ in May 2014 at a Bridgewater residence.  Since first identified in Michigan in 2002, infestations throughout the U.S. and Canada have killed hundreds of millions of Ash trees.
  • The state of New Jersey set up traps in Ash trees in 87 NJ towns to track the potential spread.  EAB has now been detected in Somerset, Mercer and Burlington counties.  With the ability to fly 1/2 mile from the trees from which they emerge, EAB infestations will spread quickly.
  • Proper identification and early treatment for Emerald Ash Borer is critical for effective protection for this destructive insect. When treated on a preventative basis, before a tree has been damaged, your Ash trees stand their greatest chance of surviving EAB damage.
  • Emerald Ash Borer beetles are metallic green with a metallic red abdomen, and measure about 1/2″ long and 1/8″ wide.  Females lay eggs on the bark of Ash trees.  After hatching, the larvae bore into the bark, feed and develop, and cut off the flow of nutrients, which eventually kills the tree.
  • Death of trees occurs approximately 3-5 years following initial infestation. 
  • Several different treatment options exist.  Organic treatment involves systemic injection into the base of the tree with TreeAzin, an azadirachtin-based product that disrupts growth, development and feeding capabilities of the pest.  Other rescue treatments include imidacloprid, permethrin, and bifenthrin.
