What's eating my hoya tsangii?

Hoya tsangii is a compact climbing hoya with small, textured leaves, grown indoors for its starry flower clusters. Mealybugs are the most common pest, hiding in the dense leaf texture and stem joints. Spider mites follow in dry indoor air. Because flowers are fragrant and attract no outdoor pests indoors, treatment stays straightforward.

Cottony white fluff tucked in stem joints, leaf undersides, and around flower peduncles; sticky honeydew and sooty residue Remove with isopropyl-alcohol-dipped cotton swabs; treat the whole plant with neem oil spray every 7–10 days until gone

Pale stippling and slight bronzing across the small textured leaf surfaces; webbing in leaf clusters Rinse foliage, raise ambient humidity, and apply insecticidal soap or neem oil spray weekly for three weeks

Tiny soft insects on new growth and near flower buds; curled leaves and honeydew deposits Wipe off or spray with water; apply insecticidal soap solution every 5–7 days until the infestation clears
