Eradicating a Mealybug Infestation That Spread Across Multiple Plants

Night‑blooming jasmine brought mealybugs (white woolly masses) that spread to other tropicals, killing them. A few plants remain healthy on the other side of the house.

Protocol

1. Spray infested plants thoroughly with rubbing alcohol in a spray bottle (front/back of all leaves).
2. Repeat twice weekly for 4 weeks (8 treatments) to kill hatching nymphs.
3. Inspect consistently; immature mealybugs are invisible without magnification.
4. Continue monitoring for 6 months after last sighting.
5. Quarantine new plants; inspect before introducing.

As long as white fluff appears, mealybugs are present.
