Does it ever seem to anyone else that we're like the pesticide/herbicide intervention group?
Seaofgreen I would try the soapy water first. It's cheap and easy. Original Dawn dish SOAP (the plain stuff not dish liquid or the antibacterial hand soap) is easy to find anywhere (big box stores, even the dollar store) and a few squirts in a spray bottle with water shaken up is easy to apply to all sides of a plant.
Thus far this has taken care of spider mites, caterpillars, and he ants seem to hate it too, in my garden. I'm also 99% sure I read a thread recently that it works for flea beetles as well.
