EAB generally have a one-year life cycle, emerging from beneath the bark of ash trees beginning in late-May or early-June with peak activity between mid-June and early-July.

By the time an ash tree shows obvious damage, it is usually too late to treat for EAB. However, preventive treatment can protect and save your ash tree.

Less than 24 hours from now (the date this blog was written), Denver City Council is set to award three contracts for nearly $2 Million to fight the emerald ash borer. Denver City Staff reported that Denver’s estimated 330,000 ash trees are at risk. The preventative program will include injecting emamectin benzoate into tree trunks. The treatment will be applied from May through October 2022.
