Wasps The Key To Containing Beetles 

Millions of trees across North America have been eaten away from the green metallic emerald ash borer beetle. So far, the beetle has not found its way to Maine. State Forest Entomologist, Colleen Teerling has spent part of the summer pairing and training volunteers with colonies of ground wasps, who feast on these type of beetles. Teerling said temporarily bagging wasps to catch the beetlesworks well, because wasps can fly to the tops of trees where the beetle begins to eat.
