Will Safari kill active larvae of Red Oak Borer?


Safari 20SG Systemic Insecticide with Dinotefuran may not completely kill the Red Oak Borer Larvae once they have bored into the the vein system of the tree. The tree may need to taken down and chipped. We recommend to consult your Master Gardner in your area as well.
