I have a nepenthes alata 'Boschiana Mimic' that is suffering from some pest. I have sprayed it twice with ortho systemic insecticide, covering the leaves and the undersides of the leaves. The pest are still her and look like they are spreading.
It is a very nice plant and it's a pretty good sized one too, pitchers are currently about 5-6"
I took some photos that I will post later to help identify the pest so we can talk about other possible treatments.
I couldn't post photos of a sick nepenthes without posting pictures of my other plants.
It might lead people to a wrong idea of my growing abilities. I'm not conceited, but I do have a green thumb whether one of my plants is suffering from pests or not. I have the plant isolated, I'm eager to eliminate the pest so I can move the plant back to my other window which gets light from fluorescents after sunset.
