What's eating my nepenthes nebularum?

Nepenthes nebularum is an ultra-highland Philippine pitcher plant cultivated indoors in cool, humid conditions. In these controlled environments the biggest pest threats are mealybugs hiding in leaf axils and spider mites triggered by any drop in humidity. Fungus gnats are common in the moist sphagnum medium used by highland Nepenthes growers.

White waxy fluff in leaf axils and on pitcher tendrils; sticky honeydew; growth tip distortion. Treat spot infestations with alcohol swabs. Spray the whole plant with insecticidal soap or dilute neem oil, ensuring coverage of undersides; repeat every 7 days.

Silvery stippling on leaves; fine webbing at pitcher junctions; rapid spread if humidity drops below ~60%. Maintain high humidity (70–85%). Wipe leaves with a damp cloth. Spray with dilute neem oil or a miticide labelled for houseplants every 5–7 days for 3 weeks.

Root damage from larvae in the moist, cool medium; adults disturb the potting surface and spread soil pathogens. Yellow sticky traps catch adults. Water by tray-flooding rather than top-watering to keep surface drier. Drench with Bti solution.
