Why is my Alocasia Zebrina getting mealybugs?

This guide covers mealybugs on Alocasia Zebrina. See also the general Mealybugs guide, watering, and light pages for this plant.

Common causes

  • New plant introduction

    Mealybugs often hitchhike on nursery plants and spread before symptoms are obvious.

  • Crowded plant shelves

    Touching foliage between pots makes it easy for crawlers to migrate.

  • Plant stress

    Overwatering, low light, and nutrient issues weaken plants and make them more susceptible.

  • Warm indoor temperatures

    Consistent room temperatures allow mealybugs to reproduce year-round indoors.

  • Missed early treatment

    Small colonies double quickly when not removed before the next generation hatches.

How to fix it

  1. Isolate the affected plant
  2. Remove visible bugs manually
  3. Apply insecticidal soap or horticultural oil
  4. Inspect neighboring plants
  5. Clean the growing area
  6. Monitor for six weeks

When to worry

Treat promptly if colonies spread to multiple plants, new growth deforms, or sooty mold appears on leaves.
