EAB adults and larvae chew through the tree’s water and nutrient-conducting tissues, strangling the tree. If there is a high population, the leafy canopy will start to thin, and nearly half of the branches may die in one year. Within 2 years of first symptoms, the canopy will be dead. Adult beetles will leave a “D”-shaped hole in the bark of roughly 1/8 inch when they emerge in June. The EAB spreads to nearby ash trees quickly decimating entire swaths of trees. That’s why it’s best to have Liscombe Tree come and inspect and take care of the slightest EAB infestation early to save your ash trees and stop the spread.
