Holes in Phalaenopsis Flowers? Thrips Are the Likely Culprit

Mysterious Flower Damage With No Visible Bugs

Your favorite Phalaenopsis suddenly has holes in its flowers. No insects seen. Past mealybugs, but not this. What's eating the blooms?

Thrips hide in potting mix by day, attack flowers at night. They're barely visible (1–2 mm), rasp petals, causing holes and distorted buds.

Insecticide labeled for thrips (systemic or contact). Follow label.
After bloom, REPOT: Clean pot, fresh bark mix. Seal old mix in plastic bag → trash.
Monitor: Thrips spread fast. Check nearby plants.

Don't wait. Thrips can transmit viruses. Early treatment saves the plant and collection.
