There’s currently an invasion happening in New England; the Emerald Ash Borer (EAB). This small, metallic green destructive beetle has spread to over 35 states, including provinces in Canada, since its discovery in Detroit back in 2002.

Carpenter-Costin_Oct2021-4-blogSince the Emerald Ash Borer made its way to 9 Massachusetts counties, including our own Middlesex and Essex counties, the invasive species has devastated Ash tree populations. In today’s blog, let’s explore how you can help stop the Emerald Ash Borer by remaining vigilant and responsive.

How Do Emerald Ash Borers Spread? Human Transportation

Unfortunately, humans can unknowingly take part in spreading the Emerald Ash Borer throughout Massachusetts.

According to Mass.gov, “EAB can be moved in any ash product– ash firewood, ash nursery stock, or any live ash cuttings. Everyone can do their part protecting our ash resources by avoiding moving ash materials.”

So, when working closely with Ash tree products, it’s essential that you leave any chips or pieces of the wood on site. This means that you absolutely do not transport Ash tree firewood off the premises.

In fact, Mass.gov asks that “to minimize the risk of introduction, no firewood can be brought into DCR campgrounds; safe, treated firewood is available for purchase at each campground.”

How Can You Help Slow EAB Spread?

First, Identify The EAB

Outside of not transporting Ash tree materials, there are a few ways that you can help slow the spread of the EAB, protecting your Ash trees and the Ash trees throughout Massachusetts. One of the best ways is to simply remain vigilant and look for the signs of EAB infestation.

These signs include:

  • Defoliation in the upper canopy
  • Branch death in the upper canopy
  • D-shaped exit holes in the Ash tree bark
  • S-shaped galleries in the areas beneath the bark (indicates larvae feeding)

And, many more. Please feel free to read our full breakdown explaining how to identify an Emerald Ash Borer infestation, where we go over the look and symptoms of an EAB invasion.

It’s essential that you stay on the lookout for an infestation, because if the EAB gets too far, it may be too late for your poor Ash tree. Outside of keeping a watchful eye for the signs, regular professional tree inspections are one of the best ways to identify the EAB early.
