Mealybugs on Cacti
Commonly affects: Cactaceae (Cactus)
White, cottony masses cluster in crevices, ribs, and around spines, secreting honeydew and weakening the plant over time.
Potential Causes
- 1Warm, dry indoor conditions favouring mealybug establishment
- 2Introduction from a nearby infested plant
- 3Sheltered crevices between ribs providing ideal hiding spots
Solution Steps
- 1Dab visible colonies with a cotton swab dipped in rubbing alcohol
- 2Spray thoroughly with insecticidal soap, working it into ribs and crevices
- 3Isolate the affected plant from other cacti and succulents
- 4Repeat treatment every 7-10 days for several cycles
Prevention Tip
Check ribs and crevices carefully with a flashlight â mealybugs hide in these sheltered spots long before becoming obviously visible.
