You can just hose them off with a thorough spray, not enough to tear the leaves but firm enough to wash off the bugs. Be sure to get the undersides of the leaves and the stems as well.
Do this a few times in the next week or two, so that you're sure to get the next generations. It will help to wash off the stick residue, as well.
I'd give the plants a shot of extra fertilizer once you get the infestation under control, as well. Maybe half strength of some soluble fertilizer will give them an immediate boost but not burn them while they are still stressed.
