Treating Soil Pests in House Palms with Rubbing Alcohol

Treating Soil Pests in House Palms with Rubbing Alcohol

Soaking a palm in water to drive out worms backfires—the larvae thrive in saturated soil. The white bugs you now see are the adult stage of those larvae.

Alcohol Drench Protocol

1. Remove the drainage tray and set the pot in a tub or sink.
2. Pour 1–2 bottles of 70% rubbing alcohol through the soil until it drains freely. This kills larvae and adults on contact.
3. Let the pot drain for 24 hours.
4. Do not water again until the soil is bone‑dry (3–4 weeks).
5. When you resume watering, apply half the usual volume, then follow with another alcohol drench. Repeat until no pests are seen.

Prevention

Water only when the soil is dry and the pot feels light. Always empty the drainage tray. A wet‑dry cycle denies pests the constant moisture they need.
