Scale treatment - any non-toxic?

Hi, I know this won't be the first time this question has been asked but I'm wondering if there is any new knowledge/wisdom in the group as to how to treat scale on bamboo? I try not to use toxic chemicals. Anyone know of a systemic, non-toxic scale killer? I just gave up growing any of the B. multiplexs - they're just scale magnets. But now I have a bad infestation on my vulgaris vittata and that's my favorite. I also have a massive infestation of Argentine ants which I can't get rid of, so that doesn't help the problem.

Usually I spray with Neem Oil or Pyrethrin, but you all know this is only partially effective and some of the little buggers always survive.

Any suggestions greatly appreciated.
