Tiny White Bugs in Phalaenopsis Pot: Repot Now or Wait?

White Bugs in the Mix—Fungus Gnats or Mealybugs?

Your healthy, nearly-year-old Phalaenopsis has new roots, leaves, and 1 cm spikes. You see tiny white bugs in the soil. Repot now (carefully) or wait until after bloom?

Identify the Bugs First

• In the mix, jumping/flying: Fungus gnats (larvae eat decaying mix).
• On leaves, especially undersides, cottony: Mealybugs.

If Fungus Gnats: Repot Now

• They thrive in broken-down, wet mix.
• Repot carefully—spikes are small but brittle. Do it in afternoon warmth.
• Use fresh orchid bark mix; discard all old mix.

If Mealybugs: Treat First, Then Repot

• Wipe all bugs off leaves/stems with alcohol-soaked Q-tips/cloth.
• Check weekly; repeat until gone.
• Then repot after bloom if you prefer.

Either Way: Don't Let Them Multiply

Both pests indicate conditions that need fixing (old mix, poor airflow). Fresh mix and good culture prevent recurrence.
