This is from the NCSU web site:
" Since the insect passes the winter in the ground, squash
should not follow squash. Land should be disked in the fall
to expose the cocoons and then plowed deeply the following
spring. Vines should always be destroyed following harvest
to prevent late caterpillars from completing their development.
Sometimes injury can be offset by late and staggered plantings
and heavy fertilization to promote rapid growth. Planting early
susceptible varieties as "trap crops" only serves as an indicator
of squash vine borer's initial presence and that control practices
should commence. Butternut 23 squash has some resistance to
the squash vine borer. An egg parasite exists but fails to destroy
borer eggs in most years. Hence, control at best, is marginal. "
The URL for CROP-NET (where the link to the NCSU site is):

They give recommendations for cultural controls (as above) and
also for insecticide use, whatever floats your boat. Good luck.
