The Emerald Ash Borer, an insect that has decimated ash tree populations across large swaths of the U.S. and Canada, is now in Vermont. The insects have now been confirmed at numerous places in the state.

Teachers Tree expects all ash trees, statewide, will eventually be affected. It’s just a matter of time. That really gives the owners of woodlands in Vermont two choices:

  • Treat their ash trees.
  • Or remove them.

Teachers Tree can help with these decisions. Use our EAB contact form, at right (or below, on your phone) to let us know if you want to talk with us about your trees

We can help landowners and municipalities deal with the Emerald Ash Borer threat by inspecting trees to determine whether they’re infested, and providing advice on how to prepare for and respond to the eventual arrival of the EAB.

As licensed professionals, Teachers Tree Service can treat healthy trees with a systemic insecticide that will last two years and be guaranteed. The treatment involves the application of chemicals, something we are usually reluctant to do, but a living ash tree is a lot better for the environment than a dead one.

While it’s likely that almost all of the ash trees in Vermont will be killed by the EAB, it’s also true that almost any individual, currently healthy tree can be saved.

Trees in infested areas will need to be treated, or removed. In other parts of the country, the mortality rate for untreated trees is near 100 percent. And infested trees should be removed promptly. Waiting till a tree dies from an EAB attack increases the expense, because trees fall apart and are unsafe to climb.

Now is the time to make plans for dealing with the inevitable arrival of the Emerald Ash Borer in your woods. Strategies include planting non-ash trees to take the place of trees that will be lost to the EAB, and selecting individual trees that are particularly important to you for treatment.

Native to northeastern Asia, the EAB was first discovered in the U.S. in Michigan in 2002, though it is believed to have arrived in the 1990’s. The Emerald Ash Borer is now established in more than 30 states and three Canadian provinces. The adult beetles are about half an inch long and metallic green. Their larvae tunnel through the wood just under the bark of ash trees, killing the tree by cutting off the flow of nutrients. Healthy ash trees typically die within three to five years of showing their first sign or symptom. All species of ash trees in Vermont are susceptible.
