How do you control cottony cushion scale on citrus?
no nymphs yet I think, have only found a few pregnant females. Should i just pick off and squash the pregnant females or should i spray?

PestOil controls some scales, not all. In your situation I would recommend removing all the mature scales and then spraying with PestOil in spring as oils cannot be used on evergreen trees during the autumn and winter months.
