The Ladybugs, and their larva, will work on the Aphids, but if the Aphids seem to be too many the best way to remove them is a sharp stream of water, and a spray bottle works very well to do that. Knock the wee buggers off the plants and they will not return although you will see more within a day or two.

VERY well said, Kimmsr!

Use your common sense to determine if the ladybug militia requires some back-up on your part, at the beginning.
