|from the Global Invasive Species Database|
The EAB is a beetle that comes originally from Asia and whose larvae have a taste for ash tree cambium (ie the layer of wood under the bark that produces new growth). Like most invasive species, it has little or no natural predators here.
Aggressive measures are necessary because EAB infestation is hard to detect before damage to the trees is irreparable. Felling trees suspected to have larvae in them and trees with a higher risk of infestation (like the ones cut down at the corner of Riverside and Tillotson) and injecting insecticide (usually imidacloprid) into the trunks of healthy trees is currently the best known practice for preventing the spread of these beetles. The insecticide treatment can last up to 2 years, hopefully giving enough time for the infestation to bypass the area or run its course.
