Sorry I didn't get back to you sooner. If you don't mind chemicals,then Sevin Dust will do the trick and is safe for food crops. A soap spray should do the trick if you don't want to use them. A few bugs won't kill the plants and I'd try the soap first to see if that will lessen your infestation.If you have a army of the things,after a couple of applications,you might want to consider the Sevin.
I'm thinking that most of your plants are container grown,so washing them will get rid of quite a few.
Let me know if this helps.
