I need to kill whiteflies on my outdoor Gardenias and want to know if Sevin Concentrate kill them. I have read that it won't.
Sevin is not labeled for white flies. You may want to use Bayer Advanced Natria Multi-insect control. This product is safe to spray on your gardenias and is labeled to treat white fly.
