Will emerald ash borer attack young trees?
The ash trees at my cottage were wiped out several years ago by the emerald ash borer. Now there are young shoots sprouting up from the dead stumps. Are these viable, or will they eventually also be killed by the insect? Should I go ahead and cut them down?

Trees that grow as "suckers" (shoots arising from the stump or ground) are a sign of stress. Removing the shoots would be wise, as they are unlikely to develop into a healthy tree. It's impossible to know whether Emerald ash borer (EAB) would attack these developing shoots. EAB remain in MI and are more likely to attack a mature tree with bark for its offspring to develop.
