What's eating my two-color cattleya?
Scale insects
Signs: Hard or soft bumps along pseudobulbs and leaf undersides; honeydew residue and eventual yellowing
Control: Remove manually with isopropyl alcohol; treat with horticultural oil spray; monitor monthly and retreat as needed
Mealybugs
Signs: White waxy fluff in pseudobulb sheaths and at roots; weakened plant, poor bloom development
Control: Swab colonies with rubbing alcohol; neem oil foliar spray weekly; consider imidacloprid drench for heavy root infestations
Thrips
Signs: Silver streaks and brown scarring on petals; deformed buds and premature flower drop
Control: Remove affected flowers; apply spinosad spray to foliage; use blue sticky traps near flower spikes to monitor
Spider mites

Two-Color Cattleya pests — FAQ
What is eating my two-color cattleya?
Two-Color Cattleya faces the same indoor pest pressure as other Cattleya species — principally scale insects, mealybugs, and spider mites. Its bicolor blooms are attractive but fragile; thrips can scar petals at bud stage. Regular pseudobulb inspection and stripping old sheaths prevents most infestations before they establish.
