Just wanted to see if anyone had tried Tricogramma wasps to control SVBs and what success they have had with them? So far I've spent money on Neem, on BT (for injecting), but am not sure its worth spending more money on the wasps. I don't want this to become a money hole.

Besides I am picking eggs by hand every day but my vines are getting very big and that is becoming almost unmanageable. I would like to see if the wasps would help but if I did get them, I would not want to pick eggs anymore, right? Since the eggs would have the parasitic wasps in them, and I'd want to make sure they hatch and create another generation, right?

Please let me know your experience.
