Sticky tape and that sort of thing will only get SOME of the adults while neem oil is largely ineffective in my experience... grab some Dr. Zymes Eliminator or some Spinosad and use as directed. They're both organic, can be used up to the day of harvest if need be, and will kill not only adults but the eggs and larvae of any leaf sucking insect (aphids, spider mites, thrips, whiteflies) ...
Good luck!
