aphids?

aphids?

Hi. I just bought a bunch of springtime herbs and repotted them last week. This morning I discovered that my comfrey plant has small white bumps on the underside of its leaves: I think they're aphids. I know ladybugs eat aphids, but I don't know how to attract them to my little container herb garden on the porch. Any suggestions for attracting lady bugs or just killing the aphids would be appreciated. Apologies in advance if this is an oft-asked newbie question: I just got here! :)
It’s cold, so cold. Well, for North Carolina anyway.
