What's eating my nepenthes mikei?

Nepenthes mikei, a rare Sumatran highland Nepenthes kept in cool humid conditions, is susceptible to mealybugs, spider mites, and scale insects — all common in indoor highland setups with warm days and cool nights. Scale is especially dangerous as it spreads quickly through a collection before being noticed.

Waxy white fluff in leaf axils and behind pitcher lids; weakened new growth and yellowing older leaves Apply 70% isopropyl alcohol on a cotton swab directly to each colony; repeat weekly; consider systemic imidacloprid for heavy infestations

Flat brown or tan oval bumps on stems and leaf undersides; sticky honeydew and sooty mould follow Scrape off manually with a soft toothbrush; follow with an alcohol swab treatment; isolate plant immediately as scale spreads rapidly

Pale stippling and gossamer webbing on leaf undersides and pitcher surfaces; worse in dry growing chambers Increase chamber humidity; rinse foliage thoroughly; apply neem oil at quarter-strength, testing on one leaf before full treatment
