“High Risk” For Emerald Ash Borer in New Jersey

emerald ash borer treatmentThe emerald ash borer is a relatively recent arrival in New Jersey. It was first spotted in the state in Somerset County in 2014. As of this summer, it’s been found in Bergen, Burlington, Mercer, Middlesex and Monmouth counties as well.

And now, the New Jersey Emerald Ash Borer Task Force says every ash tree in the state is at risk for infestation by this little green pest. The task force is made up of representatives from the NJ Department of Agriculture, the state’s Forest Service, the U.S. Forest Service, the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service and Rutgers University.

The emerald ash borer (EAB) is an invasive, wood-boring beetle that comes from Asia and made its way to America sometime in the last few decades. They’ve destroyed millions of ash trees in the last 14 years while putting another 8 billion trees at risk.

Emerald Ash Borer Treatment in PA & NJ

According to the task force:

  • It’s appropriate to begin treating high-value trees now.
  • The state recommends people work with certified tree experts to help determine whether trees need to be treated or removed. They are certified pesticide applicators and will perform any chemical treatment on trees.
  • Trees determined to be at high risk should be removed right away.
  • Actively infested trees need to be chopped down and chipped as soon as possible. Their remains should stay in your municipality. (Transporting infected ash wood across state lines is prohibited in some places.)
  • For all other trees, it’s best to remove them in fall or winter.

An infestation occurs when the adult EAB lays eggs inside a tree. The eggs grow into larvae, which feed on the tissue that brings the tree water and nutrients. This causes the tree to die slowly. It may take two or three years for the decline to become apparent. By then, it’s too late.

Still, there are ways to tell if emerald ash borers are feeding on your trees:

  • Adult EAB leave a D-shaped hole when they break the surface of the bark. The adult version of the insect is small, and a bright, metallic green.
  • After an infestation, trees may start to grow new leaves at the base or on the trunk, typically just below the feeding site.
  • Look for discolored leaves, dead branches and bark that’s beginning to split. Trees that are infested will usually die from the top down.
  • Woodpeckers love to feast on EAB larvae, and will strip away the ash’s bark to get at them.

While there are ways to spot an infestation, your best course of action is early detection and preventive emerald ash borer treatments. This treatment is at its most effective when trees are in good health and show no signs of an EAB attack.

What They're Saying

Let me start from the beginning. I had a tree fall down in my yard that crushed my deck outback, crushed an expensive canopy and blocked the back door of my house, which was a huge fire hazard had we not been able to get out of the front door. I called willow tree service and for an insurance estimate and had the absolute please to deal with Scott and his team. We made an appointment for them to check everything out and when we scheduled a time not only was he ON TIME but to the minute. Long story short insurance tried to say it wasn’t as bad as it actually was. Not only did Scott and his team (who were booked for a month in advance) work with what my insurance company gave me, within 3 days he made it his priority to get that tree away from my house and hauled away so I could exit the house safely God for bid an emergency happen. They were no surprise cost, the work that was done was impeccable and he and his men went above and beyond the call of duty. I wish there were something I could do for this man and his crew that would make up for how great I was treated and how great the work they did was done. Not only will I recommend them to neighbors and friends alike, I will call them friends myself and any future work with landscaping or a tree or trimming I will go nowhere else! Sorry to be long-winded but this needed to be said. Scott and crew I hope you see this and know you helped a family who needed that help, God bless you, God bless Willow tree service and God bless the crew!
