Has anyone tried Trichogramma wasps in their battle against Squash Vine borers? I have been battling them mainly by spraying neem, injecting BT when I see any sign of damage, and picking off eggs by hand. But the vines are getting BIG and picking off eggs is becoming a very time consuming chore... so I was wondering if enlisting some help from the wasps would help? But I don't certainly dont want to spend more money on needlessly. And if I did get them, would that mean I should stop picking eggs? I would not want to destroy the parasitized eggs, right?
