Haha! Yeah, those larvae will go to town! They weren’t enough to kill them in the greenhouses, but they did keep the populations in check for a while. Green lacewings and parasitoids also work very well (the lacewing larvae eat like ladybugs) If you are not in flower, pyrethrin will decimate them. I can’t imagine nematodes would do anything, and I’m really surprised anyone would say there are nematodes specifically for this type of aphid. I could be wrong, but I can’t even imagine how that would work. Good luck on getting rid of those things!
