You can use some Dr. Zyme's Eliminator or some Spinosad - they're organic and will kill off the adults, eggs, larvae... everything .... and you can use them on the buds as well without harming your harvest and without having to rinse off. Neem oil is fairly ineffective and sticky traps are only going to get SOME of the adults...
Since you're going to have to spray tops and bottoms of all the leaves, and given the stage they're at, I'd do some defoliation to make the job easier...
Good luck!
