Nepenthes have few pests in comparison to orchids, roses, and many other genera. Yet these pests can be detrimental to the well being of many plants. Leaving these pests unattended and monitored, they can cause serious harm to death of many plants.
Some basic insecticides when applied on a semi regular basis can control the spreading or advancing of many insect pests commonly experienced.
The main pest I have seen is the feeding of the white fly-scale-like pests found mainly on the shoots, pitchers and tendrils of nepenthes. A regular spraying of DeltaGuard (a synthetic pyrethroid form) and combining it with Merit (a systemic insecticide) also sprayed with Orthene WP (be sure to use the Wettable Powder for least phytotoxic effects) sprayed by itself or combined with a foliar spray for on-contact kill.
The duration of spraying is best at ten day intervals with concentration to the soil region just below the plant stem.
Ordinary citizens like me can no longer buy Orthene. I picked up a spray bottle of Bayer Rose and Flower insect killer yesterday and am wondering about it's use on Nepenthes. It contains Imidacloprid (Merit), which we know about from Michael's postings. It also contains Beta-cyfluthrin, which is a non-systemic, rapid-knockdown insecticide. Has anyone here used this successfully on Nepenthes?

Walter, i regularly use whats here called, Bayer 360 year round which has the same constituents, it had absolutely no negative effect on any of my plants, from consumables to Orchids, Nepenthes and other carnivorous plants, the only ones that don't like it much are Drosera, but they too don't seem to stress too much.
