The emerald ash borer (EAB) made its way to Nebraska a couple of years ago. The beetle is tiny, just one-eighth-inch-wide and one-half-inch-long. But it causes huge damage.
Infestations move through areas quickly, killing about 70 percent of unprotected ash trees within four years of initial discovery. This not only threatens our landscaping and community tree canopy, but also electric service, if ash trees are close to power lines.
EAB lay eggs on the bark of ash trees, and when eggs hatch, the larvae bore into the bark and feed on tree tissue. This cuts off the pathway for trees to receive water and nutrients. Dying trees don’t just lose leaves, they weaken until their trunks snap near the base, and trees come crashing down.
Property owners are responsible for either treating their ash trees to prevent EAB, or completely removing their ash trees. The Nebraska Forest Service offers more information safety risks and liability involving diseased trees.
Treatment needs to be repeated every one to two years, depending on the type of insecticide used, for the life of the tree. It should begin in the spring, once EAB is within 15 miles of your location. That’s the case for most of OPPD’s service territory. Costs vary, depending on the type of insecticide used. Check with a certified arborist to help determine whether ash tree treatment or removal is your best option.
