EAB Risk Status

What is eab?

Emerald Ash Borer (EAB) (Agrilus planipennis), is an invasive beetle from Asia responsible for the deaths of millions of ash trees. EAB infests and kills weak and healthy ash trees, and all species in North America are vulnearble to EAB attack.

What to do?

If you suspect your tree has been infested with EAB or you haven’t started treatment within the last few years, it will need to be removed by a professional Arborist. Treatments are costly and must be applied every 2 years, and there is no guarantee that a tree can be saved by a treatment. Often times trees are treated even after infection, which is a waste of money and resources.



The EAB larvae create tunnels under the bark while feeding and the resulting damage will cause the tree to die within one to three years typically. Emerging adult beetles will create D-shaped exit holes confirming its existence, along with the presence of woodpeckers, peeling bark, and canopy die back.


Ash trees become extremely dangerous and hazardous to property owners and removal crews alike once they are infested with EAB. Trees with greater than 1/3 or 20% canopy dieback are considered unsafe to climb, and if access issues are present, removal costs will increase.
