Mealybug Infestation on Phalaenopsis: Complete Eradication Protocol

Identifying the Problem

White "mold" that's sticky and spreading? That's mealybugs—sucking insects that multiply rapidly. The stickiness is honeydew they excrete. Cotton swab wiping only removes visible adults, missing eggs and hidden crawlers.

Radical but Effective Treatment

1. Unpot and discard all old mix and pot (bag and trash outside)
2. Trim any mushy roots
3. Blast plant with high-pressure water outdoors to remove all bugs
4. Submerge entire plant in systemic insecticide solution for 1+ hours (wear heavy rubber gloves)
5. Dry thoroughly, then repot in fresh mix and clean pot
6. Isolate in clear plastic bag for a week if odor persists

Alternative: Ongoing Manual Removal

Alcohol-dipped swabs can control small infestations but require constant vigilance. New hatchlings emerge continuously. The radical method above gives a clean slate.
