RUBBING ALCOHOLRubbing Alcohol (isopropyl alcohol) can be used to control some household insects such as scales and mealybugs.
Prepare a small container of rubbing alcohol. Using a cotton swab or cotton ball, dab the alcohol on the insect. Wait several minutes and wash off the plant.
Alcohol can dry out a plant, especially the buds and growing points. Rinsing with water within five minutes should prevent damage. Avoid using rubbing alcohol on the plants' growing points.
