Will Fertilome Borer, Bagworm, Tent Caterpillar & Leaf Miner Spray kill rhododendron stem borer larve?
Fertilome Borer, Bagworm, Tent Caterpillar & Leaf Miner Spray is not labeled for rhododendron stem borer larve. We would recommend using Hi-Yield Indoor/Outdoor 10% Permethrin Insecticide. It is specifically labeled for rhododendron stem borer. It is labeled to be used on indoor/outdoors ornamental plants, trees, shrubs, and listed fruits and vegetables.
