Infestation of ash trees by the Emerald Ash Borer begins with adult EAB females laying their eggs within cracks and crevices found in the bark (Haack et al., 3). Between late summer and early fall, the EAB will feed on the vascular cambium of its host (Haack et al., 3). Occasionally EAB larvae will go beyond the “cambial region” of the ash tree and feed on the secondary xylem found within the sapwood (Haack et al., 3). The hungry beetle larvae will later devour large amounts of phloem in their way towards the cork, and ultimately, exiting from their hosts (Haack et al., 3). If an individual has not exited its host by the end of fall, it will “overwinter”--essentially hibernate--until next spring and then complete its development (Haack et al.,
