I didn't post this early for fear of jinxing myself but my aphids have been gone now for over a month. I had a problem early on and was squishing and spraying with safer soap. They kept returing. Now I don't know if this was the reason but one day I was at my grandmothers and noticed a ladybug larvae and some eggs on her tree. I brought them home and put it on my plants. It started eating right away. About a week later I saw tiny versions of him because the eggs hatched. I week late I found one more larvae on her tree and put it on my plants again. Needless to say I haven't seen another aphid on my plants in over a month. They are gone.... all of them. I was very worried early on when nothing was working but it seemed divine intervention happened. I don't know if it was the few ladybugs or weather or whatever but all's I can say is I am very relieved.
