Emerald Ash Borer (EAB)
Ash tree with established Emerald Ash Borer infestation.
How the Insect Spreads
Emerald Ash Borer adults can fly at least 1/2 mile from the tree where they emerge. Many infestations, however, were started when people moved infested ash nursery trees, logs, or firewood into uninfested areas. Shipments of ash nursery trees and ash logs with bark are now regulated, and transporting firewood outside of the quarantined areas is illegal, but transport of infested firewood remains a problem. Please do not move any ash firewood or logs outside of the quarantined area.
