Mealybug Control on Money Plants (Pothos/Epipremnum)

Eradicating Mealybugs: The Cottony Pest on Stems and Leaf Axils

White, sticky, cotton-wool-like clusters where leaves meet stems are mealybugs—sap-sucking insects that weaken plants and spread rapidly.

Why They're Hard to Kill

• Young nymphs (crawlers) are tiny, lack the waxy coating, and hide in crevices.
• Eggs are protected in the cottony ovisac.
• Incomplete spray coverage leaves survivors that rebound.

Effective Treatment Protocol

1. Isolate the infested plant.
2. Prune heavily infested stems/leaves; bag and discard.
3. Spray thoroughly until dripping—tops and bottoms of leaves, stems, leaf axils, pot rim.
4. Repeat in 5–7 days (catches hatchlings).
5. Monitor weekly for a month.

Recommended Sprays (Low Toxicity)

• Rubbing alcohol spray: 1 part 70% isopropyl : 5 parts water + 1 tsp mild liquid soap per quart. Do not use Q-tips alone—misses hidden bugs.
• Insecticidal soap (e.g., Safer's).
• Horticultural oil (lightweight, e.g., SunSpray Ultra-Fine).
• Brand X Foliage Cleaner (silicon-based; professional grade).

Precautions

• Test spray on a few leaves; wait 48 hrs for damage.
• Never spray in direct sun or >75°F (24°C).
• Avoid systemic pesticides indoors—risk to people/pets.

Persistence and coverage win. A single missed mealybug can restart the colony.
