  • Trim off the infested leaves.
  • Moisten a paper towel with rubbing alcohol and wipe off pests like mealybugs.
  • Remove small infestations of scale insects by scraping them off using a fingernail file.

Use‌ ‌Insecticides‌ ‌Correctly‌: Read the product label and make sure the plant you are treating is safe to treat with the particular product to prevent damage. Make sure the plant isn't water-stressed before treating it. Water the plant one or two days before treatment. If a concentrate, only mix what you will use in one treatment and store it away from children. Only use the recommended amount and retreat as directed on the label.
