I just sprayed everything down with neem because I noticed a handfull of my plants had creepy crawlies (one bad shipment, etc.). The one thing in particular that I noticed was that the N.inermis growing tip had them fighting for space because it got attacked the hardest, with N.platychila coming in at a close second with them crawling all over its leaves. I think N.hamataXsibuyanensis was showing signs of bug damage first before anything else, followed by the N.spectabilis, then the N.platychila and N.mikei, and lastly the N.inermis being visibly infested with N.macfarlanei showing a stunted leaf and damage last, and N.flava just starting to get infested. Other plants seemed completely unaffected (N.chanianaXveitchii, N.truncata, N.thorelliXcampanulata, etc.).
I was wondering which plants of yours you've noticed have the most bugs, or that you have to spray down more often than others? For example, I've heard that N.hamata is particularly prone to spider mites, and I've also seen my S.purpurea, but none of the other Sarrs, infested with aphids before I bought one of those bags of 250+ lady bugs. Or how about plants that never get bugs?
The stuff works really well - I woke up to one of my drosera pots hosting a fly that seems to have forgotten how to fly. I hope I haven't just irradicated my food-stock for the plants - a fresh and healthy supply of fruit flies
