Pest identification
What's eating my hoya carnosa variegata?
Mealybugs
Signs: White cottony masses at leaf axils and stem nodes; honeydew, sooty mold, and yellowing of variegated leaves
Control: Remove manually with alcohol swabs; spray with neem oil diluted in water (1 tsp per liter) weekly for a month
Spider mites
Signs: Fine speckling and pale webbing on leaf undersides, most prevalent in winter when indoor heating drops humidity
Control: Shower foliage to dislodge mites; apply insecticidal soap or neem oil spray; mist regularly to raise humidity
Scale insects
Signs: Hard or soft bumps on stems; leaves yellow and vine vigor declines; honeydew attracts ants
Control: Scrape off with a toothbrush; swab with rubbing alcohol; treat with horticultural oil on a 2-week schedule
Fungus gnats
Signs: Root damage from larvae in overly moist potting mix; adult flies hovering around the soil surface
Control: Let the top layer of mix dry out between waterings; use sticky yellow traps; apply Bti soil drench if larvae persist
