Answer: If they are in the soft crawler stage they can be treated with insecticidal soap. They can also be treated with a horticultural oil spray. Be sure to read and carefully follow all of the label directions including for repeat applications and for which plants soap/oil can be used on. Scale can be very hard to control, so if you have one or two plants that are badly infested you may want to consider discarding them to prevent the scale from migrating to your other plants.
