If you are within 25 km of a known emerald ash borer (EAB) detection, the beetle will be in your municipality soon if it isn't already. The beetle moves quickly. It disperses by flying - some estimates suggest that female beetles could fly up to 20 km per day or even more. It also moves longer distances via infested wood products such as firewood.
After EAB is first detected the infestation progresses rapidly. Work in a forest setting shows that 98% of ash trees die within six years of the first EAB attack and this pattern is thought to be similar in urban and other environments[15,34]. Ash trees deteriorate rapidly after death, and can become hazardous.
