Note about distance:
Distance to the nearest known infestation is an important aspect in determining the risk EAB poses to your trees.

Keep in mind however that EAB tends to spread in jumps and that symptoms do not appear until EAB has been present in an area for 2 years or more. EAB densities sufficient to kill trees take 4-5 years to accumulate after reaching a new area.

Symptoms such as woodpecks and bark splitting open to reveal “S” shaped galleries can be expected to appear before significant numbers of trees succumb to the beetle.
