Wish I could be more help here, but.... When I was living in So Cal, I was cursed with an aphid infestation in my chile garden. I'm not "strictly" organic, but I do not use chemical pesticides. So, I went to the local nursery and started checking labels, and, sure enough, found an organic product that got rid of aphids. For the life of me, I can't remember the name of the stuff, but (1) it was organic and (2) it worked. I would advise you to just peruse the shelves at your local Plants -n- Things. Good luck.
