I like to use a multi pointed attack, Alcohol for topical treatment every other day for 10-12 days, Bonide Systemic in the top inch or so of soil, and a spray such as "Sevin" every 4 days or so, (not on the alcohol day) it seems to get them under control quickly...
Try spraying your plants once per week with 70 percent alcohol. When you are done spraying, let the plant dry in a semi dark area with good ventilation or a fan blowing on the plant.
