Mealybug Infestation on Peace Lily: Identification and Non-Chemical Control

Plant ID

Description matches Peace Lily (Spathiphyllum): glossy green leaves, white lily-like flowers, 3.5 ft wide, 2.5 ft tall, hanging.

Mealybug Confirmation

Small white cottony clusters and tiny beige nymphs on leaf tops and undersides confirm mealybugs.

Origin

Usually present in low numbers at purchase; stress (poor light, improper watering) triggers population explosion. Rarely spread by contact.

Treatment (Non-Chemical)

Spray entire plant until dripping with: 1 part rubbing alcohol + 6-8 parts water + squirt of liquid soap. Repeat weekly until eradicated. Thorough coverage is critical—nymphs hide in crevices.

Follow-Up

Inspect all plants weekly. Quarantine not needed after thorough treatment.
