Sticky Residue on Peace Lily? It's Scale—Here's How to Eradicate It

Nancybridget's 18-month peace lily has sticky floor and leaves for months. Otherwise healthy.

Expert Diagnosis from Will Creed

Scale insect infestation. Look for slightly raised tan bumps on leaf undersides (center vein). Older = hard dark brown shells. They secrete honeydew (the stickiness).

Treatment Protocol

1. Thoroughly drench ALL leaf/stem surfaces until dripping.
2. Repeat in 5–7 days for crawlers.
3. Check weekly for recurrence.
