Raised Orange-Brown Spots with Sticky Residue: Scale Insects

Diagnosis: Brown Scale

Raised spots + sticky slime = brown scale insects. Adults form hard shells; crawlers (transparent) suck sap, causing sticky residue. Eggs hide under shells.

Complete Treatment Protocol

1. Isolate plant.
2. Remove all visible scales with alcohol-soaked swabs (both sides of leaves, sheaths, spikes).
3. Drench entire plant (roots included) in systemic insecticide for scale (30 min, wear gloves).
4. Repot in fresh soaked mix; discard old mix/pot.
5. Air out plant outside for days (insecticide odor).

Incomplete treatment = ongoing battle. Sterilize tools; monitor nearby plants.
