Back to squash vine borers: Apparently, on occasion the borer larvae can be located and either the vine stem carefully cut in to in the direction of the vine, to kill the borer, or the larvae can be punctured with a needle or Exacto knife, the latter again oriented “with” the vine. But, how to locate the larvae?
This might be worthwhile when just a few plants are involved, esp. a particularly valuable plant like my last Opo.
Here’s a video of where to find the larvae of the Squash Vine Borer. About 10 minutes.
Also - ICK! LOL!

Quality is poor, but you’ll get the gist of it.
