Sirex Woodwasp

Sirex woodwasp (Sirex noctilio) is native to Europe, Asia, and northern Africa. They  primarily attack living pines whereas native woodwasps attack dead and dying trees. It was detected in New Hampshire in 2022, but we do not expect it to be a damaging pest in the state

Awareness of the symptoms and signs of a sirex woodwasp infestation increases the chance of early detection, and thus, the rapid response needed to contain and manage this exotic forest pest.
