We look forward to hearing from you. Emerald Ash Borer, since it's discovery, has killed more than 20 million ash trees in Michigan, Ohio, Indiana and Illinois. Our area in Illinois is currently under quarantine for this devastating pest. Symptoms: Adult beetles feeding on leaves mid May through mid July. Dead or dying branches usually near top of tree. D shaped exit holes in branches and trunk of tree. Vertical splitting of bark S shaped galleries on the wood surface beneath the bark. Sprouts or suckers growing at base of tree trunk. Extensive univeristy research has demonstrated that professionally applied insecticides are the only method of protection. We must either cut down our ash trees or begin insecticidal treatment to save them.
