Hi
What kind of garden you have ? I've got more than 200 fruit trees and vegetable garden, and I don't have aphid issues. First year I came, yes, some attack of aphid in orlander and citrus, but I make ecological managment and since 4 years, I see almost no one aphid.
If you have massive aphid attack, it's because a wrong managment. First avoid quimical fertilizante, because the excess of nitrogen attrack strongly aphip for kilometers. I recommend slow fertilizante and natural one, made of carbon matter like horse manure. Sheep manure or chicken one are very strong fertilizante, so the suitable dosis will make the job.
There is many insects that eat the aphid, not only the ladybug, but also waps, mantis, earwig, dragonfly, hoverducefly, etc. It depends the kind of garden, because these insects need a habitat, zone to reproduce, flowers, fresh places, etc.
Another solution it is the used of blacksoap diluated with water and spread on the affect plants and leaves. The soap disolves the skin of aphids. In case you don't have diversity in plants but just isolated plants here and there, it could be your solution. But take in mind the main issue comes from exces of nitrogen, inappropiate fertilization.
