I'm having the same problem. They look like aphids, only black. Lady bugs seem to be eating them, but there's not enough lady bugs to really make a difference. I've been making a spray of 2 Tbsp. dish soap, 2 tbs veg oil in a spray bottle of water. Then blast them with it. On alternate days I just knock them off the plant with the force of the water from the hose. Seems to be helping, but I notice the ends of the plants are dying where they were.
And I had just gotten these plants looking good after a couple winter's ago when the rabbits completely girdled them.
