I'm done fighting them. I'm ONLY growing C. moschata species of squash this year. Moschata's have solid stems and it's said that SVB's don't bother them.
I have Tromboncino for summer squash -- just harvested my first fruit this morning and am planning to put it in pasta sauce later -- and Seminole for Pumpkin/winter squash. Butternut is another one but I wanted to try something new.
There are quite are few varieties to try so I think I'll keep growing different ones if this year is successful.
