Emerald Ash Borer Community Preparedness

Emerald ash borer (EAB) is a devastating wood-boring tree pest that has killed millions of trees in the eastern and central U.S. While EAB is all but impossible to eradicate once it arrives in an area, well-planned response efforts can slow its spread and reduce the impact on community forests. A response plan is important because it provides a community with the opportunity to plan ahead to spread the costs and losses associated with the impacts of EAB.

  1. Greetings! There is a tree, either on our property or the neighbor’s property, that has been tagged with a green spray painted ring, number and letter on it. I phoned the city and they confirmed that this tree has been marked for removal because of Emerald Ash Borer. Is there anything we can do besides cut it down? Do we need to consider a specific tree company, one licensed to eradicate EAB? Are there programs to help communities deal with the cost of tree removal because of this insect? Will our family or the neighbor need to act fast? Thank you so much for helping me to address my questions and concerns.

    1. Thanks for your message Kate. I would encourage you to contact the MN Department of Agriculture’s Arrest the Pest program (arrest.the.pest@state.mn.us or 1-888-545-6684). They will be able to help answer some of your questions. Depending on where you live, you may need a permit it you are seeking to treat a tree (i.e., see this page for how to access a permit for treating boulevard trees in St. Paul). But, if a tree is destined to be removed, it might be best to keep in contact with your local contacts (i.e., the city). -Matt

  2. Hello,

    I have a green ash in my yard. It is still healthy and an arborist recommended an emamectin benzoate trunk injection to prevent EAB. I am concerned about doing this for its potential toxicity to insects, birds, other plants, wildlife, etc. Can you provide any information regarding this? Thank you.

  3. Hi Jane,

    I happy to hear you’re not only concerned about your tree, but also about the other natural life in your area. The research has shown that as long as emamectin benzoate is used as directed, the risk of harming other plants, animals, or insects is very low. Your tree care provider also has more control of where the chemical is going because they plan to use an injection and not a spray or soil drench.
