I found this in several places, and it seems like most people who try, have great results with aphids leaving in a few days. Here is link to one post about it:

I am eating and freezing some bananas now, and cutting peels in small pieces. I have each year tons of aphids on cucumbers and melons. But then I have ants, that farm them too. I am baiting ants with borax/sugar/peanut butter, so hopefully that will reduce them, and then banana peels hopefully will do the rest. Some people think it is potassium, that repels aphids as they seem to prefer plants, that have too much nitrogen.
