The Emerald Ash Borer (Agrilus planipennis or EAB) is responsible for the destruction of tens of millions of ash trees in 19 states in the Midwest and Northeast. Native to Asia, it likely arrived in the United States hidden in wood packing materials. The first U.S. identification of Emerald Ash Borer was in southeastern Michigan in 2002. It is especially dangerous because there is no known treatment for EAB infestations – trees must be felled and the wood disposed of.

What You Can Do


















What You Can Do

  • Don't move firewood. EAB larvae can survive hidden in the bark of firewood. Remember: buy local, burn local.

  • Inspect your trees. If you see any sign or symptom of an EAB infestation, contact your State agriculture agency.

  • Talk to friends, neighbors and co-workers about EAB and what they should be aware of on their trees.

  • Ask questions. If you receive ash nursery stock or firewood, know its point of origin and your supplier, as larvae could be hiding under the bark.

  • Know State and Federal regulations. Make sure you understand regulations that govern your state and those you may visit.

  • Know the quarantines in your area and learn to leave Hungry Pests behind.
