Thrips on Nepenthes glabrata: Identification and Treatment

Discolored Leaves on a Highland Nepenthes? Check for Thrips

Silvery‑brown patches on N. glabrata leaves, especially on the undersides, are classic thrips damage. Use a hand lens to spot the slender, yellow‑brown insects.

Effective Treatments

• Neem oil – organic, repeat every 7–10 days.
• Permethrin‑based spray – synthetic, fast acting. Avoid on blooming plants.
• Do NOT use imidacloprid (Bayer) – thrips are largely resistant.

Treat promptly; thrips multiply quickly in warm, humid terrariums.
