Tiny White Bugs in Orchid Bark: Mealybugs or Scale, Not Spider Mites

Identification

White bugs in bark = likely mealybugs (cottony) or scale (hard bumps). Check leaf undersides—their favorite hideout. Spider mites are microscopic, cause stippling/webbing.

Immediate Removal

• Wipe leaves with isopropyl alcohol on soft cloth (base to tip).
• Repeat several times.

Systemic Treatment (Essential)

1. Buy orchid-safe systemic insecticide (garden center).
2. Apply 3× at 1-week intervals (catches hatchlings).
3. Follow label exactly.

Prevention

Preventive spray early spring and mid-fall. Quarantine new plants. Inspect regularly.
