Mealybug Infestation: Why Repotting Alone Fails and How to Achieve Complete Eradication

Identification

Fuzzy white bits = mealybugs. Young stages lack the white coating and hide in leaf/stem joints.

Why Repotting Doesn't Work

Mealybugs are on the plant, not just in the soil. Fresh soil doesn’t remove them from stems and leaves.

Effective Treatment: Complete Coverage

• Brand X Foliage Cleaner (silicon-based, penetrates crevices). Source: Southwest Plantscape Products, 1-800-333-7977.
• Alcohol spray: 1 part rubbing alcohol : 5 parts water + dash of liquid soap. Spray ALL surfaces to dripping.

Critical Steps

1. Treat thoroughly, including hidden areas.
2. Repeat in 5–7 days to catch hatchlings.
3. Weekly inspections thereafter.
4. Never spray in sun or above 75°F.
5. Test on a few leaves first.

Persistence Wins

Mealybugs require multiple treatments. Missing even a few ensures reinfestation.
