Here is a natural insect spray: Blend together 1 garlic bulb, 1 small onion, 1 t cayenne pepper, 1 quart water. Steep one hour and add 1 T liquid hand soap. Store in the refrigerator.
and you just spritz this onto the plants themselves and it gets rid of the aphids?

Plant allium (chives, garlic, onions) as companion plants surrounding or bordering the plants which are susceptible to aphids. The allium has to be in the ground year round. This method has kept my garden aphid-free for 15 years, even though it is neighbored by aphid-laden trees.
I have onions growing right next to my lettuce in the garden, but it doesn't seem to be keeping them away. When I shake the lettuce, they fly EVERYWHERE. *sigh* what a pain.
