Pest identification
What's eating my nepenthes inermis?
Mealybugs
Signs: White cottony clusters tucked into leaf bases and around the pitcher attachment point; sap drain stunts already-slow growth
Control: Use a cotton swab soaked in 70% isopropyl alcohol to spot-treat each colony; repeat every 5 days for a month — do not spray broadly on this sensitive cultivar
Spider mites
Signs: Silvery stippling on leaf surfaces; fine webbing visible when humidity drops; pitchers may fail to develop fully
Control: Restore humidity to 70%+ immediately; rinse foliage with cool water; separate from other plants and monitor for 3 weeks
Aphids
Signs: Small soft insects on emerging growth tips; distorted pitcher development and sticky residue
Control: Remove manually with tweezers; a gentle water rinse dislodges light infestations; avoid neem oil or soaps unless infestation is severe

What is eating my nepenthes inermis?
Nepenthes inermis is a delicate Sumatran ultra-highland species kept in cool, very humid conditions. Mealybugs are the most common pest threat, hiding in tight leaf axils. Spider mites can appear if humidity slips. This sensitive species responds poorly to chemical sprays — manual removal with alcohol swabs is safest.
