What's eating my obscura wax plant?

Hoya obscura is most commonly attacked by mealybugs, which hide in leaf axils and along stems. Spider mites and scale insects also target this compact wax plant. Inspect regularly, especially where leaves meet stems, and treat early with isopropyl alcohol or insecticidal soap to prevent colony spread.

White cottony fluff in leaf axils and stem joints; sticky honeydew on leaves; stunted new growth Dab colonies with 70% isopropyl alcohol on a cotton swab; spray the whole plant with insecticidal soap every 7 days for 3 weeks; isolate the plant immediately

Tiny stippled yellow dots on leaves; fine webbing on undersides; leaves look dull and dry Increase humidity; rinse foliage with water; apply neem oil or insecticidal soap spray weekly; repeat for 3–4 weeks

Brown or tan waxy bumps on stems and leaf undersides; sticky honeydew; yellowing leaves Scrape off visible scales with a soft toothbrush; wipe down with rubbing alcohol; follow up with horticultural oil spray
