Research shows that EAB can have a one to two-year life cycle. Adults begin emerging in mid to late May, with peak emergence in late June. Females will begin laying eggs about two weeks after emerging. Eggs hatch one to 2 weeks and bore themselves through the bark and between the bark and wood, where nutrient levels are high. The larvae feed under the bark for several weeks, typically from late July through October. The larvae reach full size of 1 to 1.25 inches long. It is very rare that an adult EAB will be sighted. Therefore, we encourage residents to look for signs and damage rather than the actual beetle itself.
