Aphids - How to control???

[luke]

For the past couple of years in the late summer I have had aphids on several ornamentals in my yard. This year they have spread to my garden.

I have used several differenct spays in the past for my ornamentals, and still have concentrate of a few brands.

Can any of you recommend what you have used in the past to get rid of the aphids while not harming the ripe tomatoes?

Thanks
