Mealybugs are small, soft-bodied insects covered with a white, cotton-like substance. They often cluster in hidden areas such as the base of pads, between spines, or along the crevices of the cactus.

- Stunted or deformed pads
- Yellowing or wilting of the cactus

Effective treatment involves manual removal, natural remedies, and preventive care. Prompt action can prevent the infestation from spreading.
Manual Removal
Use a soft brush or cloth dipped in alcohol to gently wipe away mealybugs. For stubborn infestations, you can use tweezers to remove clusters carefully. Always dispose of removed pests away from your plant.

Apply neem oil or insecticidal soap directly to affected areas. Repeat treatments weekly until the pests are gone. Ensure thorough coverage of all plant surfaces, including the undersides of pads.
Prevention Tips
- Inspect new plants before introducing them to your collection
