Black Bugs on Alocasia 'Polly': Scale, Mites, or Thrips?

Tiny Black Pests on Plant and Surrounding Surfaces

Pinhead-sized black bugs on Alocasia, ceiling, floor, table; white fuzz on soil.

Identification and Action

• Scale insects: Usually brown, suctioned. Could be immature.
• Spider mites: Tiny, not black.
• Thrips: Black, flying.

Treatment

1. Wash plant with tepid water and cloth.
2. Spray insecticide per label.
3. Isolate plant.
4. Remove white soil fuzz; top-dress with fresh compost.
5. Sponge leaves regularly to deter reinfestation.

Take an infested leaf to the store for ID. Alocasia is notoriously difficult; consider easier foliage plants if this fails.
