EAB requires only their host trees – native ash. In natural forest settings, ash is very common. It is also widely used as a street tree in urban and suburban areas.
Threats & Impacts:
Larvae feed on bark tissue, effectively girdling the tree. EAB has killed tens of millions of trees in the U.S.
Eradication is not an option. Reducing the transport of infested ash nursery stock, firewood, unprocessed ash logs, and other ash products can slow the spread. Insecticide can be used to save ornamental or street trees but is not viable for treating at a landscape level. Biological controls are being explored. Prevent the spread of EAB by not moving untreated firewood, buy firewood local to where you will burn it, or purchase heat treated firewood.
