Aggressive yellowjacket species has moved into Massachusetts

A dangerous species of yellowjacket that hails from as far south as Central America is now buzzing around in parts of New England, experts are warning.
The southern yellowjacket, also known as Vespula squamosa, is aggressive and potentially lethal. Not only do they sting, but they bite too, according to Norm Patterson, a self-proclaimed “yellowjacket expert” who has decades of experience removing insects from homes.
