Mealybug Infestation on Orchid Leaves: Aggressive Treatment Protocol

Evelyn's orchid had brown/red leaf edges spreading, white stuff on leaf backs. Expert: likely mealybugs (cottony mature insects). Isolate plant and check neighbors. Unpot, discard mix and pot. Spray plant with water outside, dry. Drench in insecticide for mealybugs (e.g., Bonide "Eight")—submerge all parts, wear chemical gloves. Repot in fresh mix, clean pot. Keep outside semi-shaded 1+ week before bringing in. Photo would confirm.
