Pest identification
What's eating my nepenthes edwardsiana?
Mealybugs
Signs: White cottony clusters at leaf axils and along midribs; sticky honeydew residue; yellowing and distorted new growth.
Control: Dab individual colonies with a cotton swab dipped in 70% isopropyl alcohol. For heavier infestations spray with insecticidal soap solution, repeating every 7 days until clear.
Scale insects
Signs: Brown or tan waxy bumps fixed to stems and leaf undersides; leaves yellow and drop; sooty mould can develop on honeydew.
Control: Scrape off scale with a soft toothbrush, then wipe down with a damp cloth moistened with dilute neem oil. Repeat weekly for a month.
Fungus gnats
Signs: Adult gnats flutter around the media; larvae feed on fine roots in the moist sphagnum mix, causing slow growth and wilting.
Control: Allow the surface of the medium to dry slightly between waterings where the species tolerates it. Use yellow sticky traps for adults; drench with a Bacillus thuringiensis israelensis (Bti) solution to kill larvae.
