Neem oil maybe? I use it for citrus, never heard of it being used on anything else though. Research it before you use it.

See my post on systemics on the thread below. The Bayer procucts with imidacloprid should work on aphids (check the label to be sure). Neem oil also works, but you have to respray at frequent intervals, which is impractical indoors for me in the winter. If you catch the aphids early enough, they are usually clustered around a couple of flower buds - if you pinch off the buds and throw them away in a covered trash can outside, you can often stop the problem right there, especially if you follow up with a neem spray.

I don't know the effect on hummers, etc. that drink the nectar of either one of these products.
