Answer: Based on your description I think you may have seen aphids. These can be controlled with commercially formulated insecticidal soap treatments but you must repeat the sprays to catch subsequent generations of the pest -- soaps do not have a residual effect so you must actually contact the pest with the spray. When you spray, be sure to contact all parts of the plant including the undersides of the leaves and the stems. Read and carefully follow all of the label directions for best results.
