These plant-sucking pests are a familiar problem in greenhouses, in gardens, and on indoor plants. Here’s how to control mealybugs naturally with beneficial insects, insecticidal soaps, and other natural techniques.
Adults (1/10 — 1/4 inch long) are soft, oval distinctly segmented insects that are usually covered with a white or gray mealy wax. Small nymphs, called crawlers, are light yellow and free of wax. They are active early on, but move little once a suitable feeding site is found.
