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 T & L Tree come and inspect and take care of the slightest EAB infestation early to save your ash trees and stop the spread.
