Emerald Ash Borer Prevention and Treatment

How Arbor Ace Tree Service Treats Emerald Ash Borer

We drill multiple holes at a certain depth, then inject imicide into the tree.  The transpiration of the tree coupled with the pressure capsule injection allows the imicide to fully treat the entire tree.    The treatment is done by a NJ Certified Tree Expert and Commercial Pesticide Applicator.

Early Detection is a key factor in the effective treatment of Emerald Ash Borer!

What is an Emerald Ash Borer?

A dark green, metallic bug shaped like a bullet, and it feeds on the leaves of ash trees. The Emerald Ash Borer(EAB) infestation is difficult to detect in the early stages, but the damage can be severe if not prevented properly. EABs were not identified in America until 2002, and has been characterized as the most invasive forest insect to invade North America. Since the discovery of the EAB, it is estimated that the insect has killed hundreds of millions of ash trees.

Native to China, Russia, Japan and Korea, the EAB travelled to North America through wooden packing materials, or imported firewood. Insects that tend to be confused as an EAB are Honey Suckle Flat Headed Borers, Click Beetles, Six-Spotted Tiger Beetles, Green Ground Beetles and more.

What are the signs?

Yellow or wilted foliage, or decreased density of healthy-looking leaves
Heavily infested trees will display canopy die-back, which is when the top of the tree thins out
Many small holes, like ones a woodpecker may impress upon wood
Exit holes in the shape of a capital D, creating an emergence hole that is about 1/8 inch in diameter

Interesting Facts About the EAB

The EAB threatens the source of ash trees
The most extensive damage is done during the larva stage(larval), because the EAB larva feeds on tissue in the tree that delivers water and nutrients to the tree
Adult EABs begin emerging in Mid-Spring with peak emergence in early to Mid-June
About two weeks after emerging, adult female EABs begin to hatch eggs
Larva feed for several weeks before entering the Pupal Stage. Once the Pupal Stage is complete, adults begin a new life cycle
Adult EABs only live for about three weeks
