Answer: Without seeing them I have to take an educated guess that they are aphids. Aphids can be controlled with repeated sprays of insecticidal soap. If you do not think they are aphids, collect them by pulling off an infested leaf and putting it in a sealable plastic bag. Then take the bag to your local cooperative extension office or well staffed nursery and ask them to identify the pests. Once you know what you're dealing with you can choose the appropriate control measures.
