Whitefly has been bad here too. I use orthenex myself on my Confederate Roses which were infested. I spray twice with it . The second spray is about 4 - 5 days later with orthenex then finish up with Pyola which is an oil based plant based insecticide .. the Pyola will kill the eggs. The first spray gets around 1/2 of them, the 2nd the rest and the Pyola finished them off .. I always spray in the late evenings making sure I get the underside of the leaves really saturated.
