Sometimes regular dishwashing liquid works. Dilute a tablespoon in almost a gallon of cool water and add a tablespoon or two of rubbing alcohol. Take care of lots of different buggies. You should wash the
plant gently with a soft washcloth or paper towel. Repeat once a week until pests are gone. However, the browning of your
plant may not be pest related. Have you seen any insects or found any honeydew (sticky substance on leaves and furniture near the
plant; indicates scale bugs and attracts ants and mold) ? Hope this helps.
