White Bumps on Phalaenopsis Leaf: Mealybug or Benign Growth?

Alcohol Test: Mealybugs = Soft/Cottony/Removable

If alcohol Q-tip removes them → mealybugs. Remove ALL visible, check under leaves/crevices, repeat as eggs hatch.

Hard Bumps = Likely Benign

If alcohol doesn't budge them: check leaf underside for entry hole (insect puncture, healed). If no hole → abnormal tissue growth, harmless.

Sanny, good catch either way. Hard bumps with no puncture = nothing to worry about.
