Mealybugs on Orchid Leaves: Alcohol and Systemic Treatment

Tacky White Stuff = Mealybugs

Rub alcohol on cotton over spots—if brown flecks come off, it’s mealybugs. Mild infestation: remove with alcohol. Also treat with systemic insecticide (absorbed into tissue). Eggs/hidden stages require follow-up sprays.
