To kill many types of bugs such as mites, aphids, mealybugs, scales, and white flies that attack houseplants, soak a cotton ball with
isopropyl or rubbing alcohol and wipe the plant's leaves. To treat larger plants, or multiple plants, combine one cup of alcohol to one quart of water in a garden sprayer and coat the plant's leaves. Routine cleaning of your plants will keep your garden free of these annoying pests!
