Mealybugs are white, fluffy pests that also feed on sap and can cause yellow leaves, stunted growth, and a sticky substance on the plant. To control mealybugs, remove them manually with a cotton swab or soft brush, or spray the plant with a mixture of water and insecticidal soap or neem oil every 5-7 days until the infestation is under control.
