Sticky Houseplants? Scale or Mealybugs—Complete Treatment Guide

Multiple Plants with Sticky Residue: Severe Infestation Protocol

Sticky leaves on Ficus + spreading to others = scale or mealybugs. Honeydew (sticky secretion) is the hallmark. Severe, multi-plant infestations need systematic action.

Identify the Pest

• Scale: Oval, raised bumps (1/8") on stems/undersides. Translucent young → hard brown shells. Don't look like bugs.
• Mealybugs: White, cottony clusters in leaf axils, stem joints. Young lack wax, hide in crevices.

Complete Treatment Plan

1. Triage: Discard badly infested, unhealthy plants. Prune leggy growth on keepers—less tissue to treat.
2. Isolate all affected plants.
3. Spray thoroughly: 1 part 70% alcohol + 5 parts water + 1 tsp mild soap. Drench every surface to dripping.
4. Repeat in 5–7 days for crawlers/hatchlings.
5. Weekly checks for 8 weeks.

Critical Rules

• Never spray in sun or >75°F.
• Test on few leaves first.
• Q-tip dabbing fails—misses hidden pests.

Prevention Going Forward

• Inspect new plants 2 weeks before introducing.
• Keep plants healthy (right light, proper water).
• Monthly leaf wipe-downs catch early signs.
