Sticky Schefflera Leaves: Honeydew and Mealybug Treatment

What the Sticky Substance Means

The clear, sticky coating on leaves is honeydew—excrement from sap-feeding insects. The white secretions suggest mealybugs: soft-bodied, oval insects covered in white, cottony filaments that protect them from pesticides.

Confirm the Infestation

• Check leaf undersides, stem joints, and crevices
• Look for cottony masses and tiny oval insects
• Inspect pot rim, saucer, and surrounding surfaces

Manual Removal (Best for Light Infestations)

1. Dip cotton swabs in 70% isopropyl alcohol
2. Touch each mealybug individually
3. Check daily for 2 weeks, then weekly for a month
4. Alcohol dissolves protective wax, killing on contact

Systemic Insecticide (For Heavy/Recurring Infestations)

• Granular: Mixed into soil, absorbed by roots. Slow (5-10 days) but long-lasting
• Spray systemic: Applied to foliage, absorbed through leaves. Faster contact kill plus residual protection
• Both distribute throughout plant tissues, poisoning sap-feeders
