Azamax is wonderful and gets them every time. It also gets everything else. I live in a dog friendly apartment complex so I'm more prone to pests(although aside from gnats I've been lucky) so I treat with azamax as a preventative measure. It's safe and doesn't alter the taste of my buds and you can use it right up to harvest. I do soil drenches once every other week and I have a happy garden! Plus it's all natural Good luck!
