Treating Scale Insects on Indoor Palms

Sticky Residue = Scale or Mealybugs

"Palm" covers many species. Shiny, sticky liquid (honeydew) plus no visible insects strongly suggests scale insects—small, immobile bumps (match-head size) that suck sap. Mealybugs (white cottony flecks) are close relatives.

Treatment

1. Mix 5 parts water, 1 part isopropyl alcohol, 1 squirt liquid dish soap.
2. Spray all leaf and stem surfaces until dripping wet.
3. Messy but thorough coverage is the only way to eradicate.

Check for Underlying Stress

Pests attack weak plants. Overpotting, wrong light, or improper watering are often the real problem. Fix those too.
