Insecticidal soaps and regular washings can help limit insect build-ups.
Rubbing Alcohol (isopropyl alcohol) can be used to control some 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.
Cactus and succulents are commonly infested with mealybugs as are many flowering plants.
