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

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

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.
