Mealybug Infestation

Mealybugs are small, soft-bodied insects that secrete a white, waxy, cottony substance to protect themselves. They congregate in the leaf axils and root junctions of Phalaenopsis orchids, sucking sap and causing leaf yellowing.

Very Common

How to confirm: Use a cotton swab dipped in rubbing alcohol to dab the spots; if the white residue dissolves and turns brown, it is likely mealybugs.

Scale Insects (Cottony Scale)

Certain types of scale insects produce a white, fluffy appearance that can mimic cotton. These pests attach to the orchid's stem or leaves and feed on the plant's vascular system.

warning

Sclerotinia or Botrytis (Early Stage)

In high humidity environments typical for Phalaenopsis cultivation, fungal pathogens can manifest as white, fuzzy mycelium on decaying organic matter or leaf edges.

Common
