Scale on Peace Lily: Source, Spread, and Systemic Solution

Scale on Peace Lily: Source, Spread, and Systemic Solution

Found scale on your peace lily near a fruit bowl? Fruit, soil, or clothing can introduce crawlers (mobile babies). They fly briefly—can spread to nearby plants.

Scale Facts

• Not harmful to humans.
• Prefer certain plants—won't infest everything.
• Inspect all plants weekly during watering.

Two Treatment Paths

Alcohol persistence: Q-tip dab adults, spray 50/50 alcohol twice weekly 3–4 weeks.

Systemic ease: Bayer Advanced Tree & Shrub Protect & Feed (imidacloprid) soil drench. 2 tbsp/5 gal water. Lasts 3–4 months indoors. Safe on all Darlene's houseplants. ~$20/bottle, very dilute.

Prevention

Keep fruit bowls away from plants. Quarantine new plants 3–4 weeks.
