Mealybug Infestation on Pothos: Identification and Treatment

White Fluffy Substance = Mealybugs

Mealybugs hide in leaf axils, stem joints, and undersides. Young crawlers lack the white wax and are nearly invisible.

Treatment: Thoroughness Is Everything

1. Brand X Foliage Cleaner: Best non-toxic. Penetrates hiding spots. Southwest Plantscape Products (1-800-333-7977).
2. Alcohol Spray: 1 part rubbing alcohol + 8–10 parts water. Spray to drip point on ALL surfaces. Repeat in 5–7 days.
3. Soap & Water Wash: Dish-soap dilution. Submerge foliage or spray thoroughly. Same repeat schedule.

Critical Rules

• Never spray in direct sun or >75°F.
• Test on a few leaves first; wait 2 days.
• Isolate plant during treatment.
• Check weekly for months—mealybugs are persistent.

The bark in the mix didn't cause this; mealybugs came on the plant or from nearby plants.
