What's eating my hoya pubicalyx 'red buttons'?

Hoya pubicalyx 'Red Buttons' is a vigorous vining hoya grown indoors, sharing the pest profile of the species. Mealybugs hide in its dense twining stems, while spider mites strike in dry conditions. Scale occasionally establishes on older woody stems. Fast growth means infestations spread quickly without regular inspection.

Fluffy white colonies at node junctions and under leaves; honeydew trails and sooty mold on foliage Isolate plant; use alcohol swabs for spot treatment; apply neem oil spray over the entire vine weekly until gone

Bronze or yellow stippling on leaf surfaces, webs on undersides; damage worsens in heated, dry rooms Rinse vine thoroughly; spray insecticidal soap to all leaf surfaces; increase room humidity to above 50%

Shell-like tan or brown bumps along older stems; foliage yellows and growth slows Scrub scales off with a soapy toothbrush; apply horticultural oil every 2 weeks; check for crawler emergence in spring
