Indoor Ficus Scale Infestation: Organic Neem Oil Treatment

Problem Identification

Helen's Ficus benjamina has brown scale with honeydew on leaves and floor. Considering alcohol-water-soap spray but seeks better options.

Recommended Solution: Pure Neem Oil (Dyna-Gro)

  • Organic, non-toxic — safe for indoor use
  • Non-washing formula — builds protection over time
  • Multi-action: Insecticide, fungicide, miticide
  • Mode: Alters leaf taste → pests leave (doesn't kill beneficials)
  • Soil spray: Controls fungus gnats and soil pests

Why Avoid Alcohol/Soap Mix

  • Temporary contact kill only
  • No residual protection
  • Repeated applications needed
  • Risk of leaf burn on sensitive ficus

Application Protocol

  1. Spray entire plant thoroughly (both leaf surfaces, stems)
  2. Spray soil surface
  3. Reapply to new growth only (old growth remains protected)
  4. Monitor for clean new leaves as success indicator
