Mealybugs on pothos
What's Happening
Mealybug infestations on pothos appear as white cottony masses in leaf axils and stem joints where the piercing-sucking insects extract plant sap. The waxy secretions protect colonies while honeydew excretion promotes sooty mold growth. Pothos' vining growth habit provides numerous sheltered crevices ideal for colony establishment and spread.
How to Fix It
- 1
Isolate infested plant immediately to prevent spread to collection
- 2
Remove visible mealybugs with cotton swab dipped in 70% isopropyl alcohol
- 3
Apply insecticidal soap or neem oil (1% solution) thoroughly to all leaf axils, stems, and undersides
- 4
Repeat treatment every 5-7 days for 3-4 cycles to catch newly hatched nymphs
- 5
For severe infestations: take healthy cuttings and propagate in fresh sterile medium, discarding mother plant
What You'll Need
How to Prevent It
Inspect all new plants thoroughly before introducing to collection; maintain 40-60% humidity to discourage pest establishment; avoid over-fertilizing with high-nitrogen formulas that produce succulent growth attractive to pests; wipe leaves monthly with damp cloth to remove dust and inspect undersides; quarantine any plant showing suspicious white deposits.
