This is difficult to erradicate completly.Have to keep at it. You can use orthene or isotox. Spray plant and put in dark plastic bag in shade for several hours. I have also had luck spraying with full strength alcolol ond/or dabbing masses with an alcohol swab. Under each mass are eggs. Alcohol does not seem to harm plants. I put it in a spray bottle. Hope this helps. Barbara Jones BBROWJ@AOL.COM MASS z4b/5
