The SVB are the most frustrating pests in my garden. Nothing else so totally destroys a big healthy plant so fast. I don't mind the things that just nibble on leaves... This year I gave up on growing zucchini, which the SVB's always get eventually, despite my best efforts. I put tin foil collars around the stems of mine last year, but they still eventually got it ( a little slower than other years and I did get a few zukes first, but still).
This year I'm growing acorn squash. I realized later that butternut squash is the one that is resistant to SVBs (because no hollow stem) not acorn. But all my squash plants are planted in the middle of lots of other stuff and so far are doing fine... Will report more later.
Here's another article about SVB control:

A couple things it doesn't mention are kaolin clay, sold as Surround, which is sprayed on and "acts as a physical barrier preventing insects from reaching vulnerable plant tissue. It acts as a repellent by creating an unsuitable surface for feeding or egg-laying. The uniform white film may also disrupt the insectÃ¢â‚¬â„¢s host finding capability by masking the color of the plant tissue. Furthermore, particles of kaolin act as an irritant to the insect. After landing on a treated surface, particles of kaolin break off and attach to the insectÃ¢â‚¬â„¢s body triggering an excessive grooming response that distracts the pest." https://web.pppmb.cals.cornell.edu/resourceguide/mfs/07kaolin.php
There's also trichogramma wasps which can be purchased on-line and which parasitize the eggs of the SVB's
I'm thinking I will try zucch's again next year with a couple of these methods. In the meantime, not much point at being mad at Mother Nature for being who she is.
We just have to find ways to co-exist.
