James from Mosinee, Wisconsin writes

Will Onslaught Insecticide work on Columbine Sawflies?


Onslaught Insecticide is labeled for European Pine Sawflies, Red Pine Sawflies and Redheaded Pine Sawflies, but not for Columbine sawflies, specifically. You could certainly test a small area before treating a large area.
