You can also inject some BT worm killer or Spinosad inside the vine where you pulled the borer out (in addition to what caralb suggested). I've never had a borer attack so I can't speak to the effectiveness of it but it's worth a try.

To prevent them in the future, spray the base of the vines with a pesticide like BT or Spinosad every 7 days.

I've had some success using the method in the video:

Excellent suggestion Coralb,BTW I enjoyed you blog :) I can totally relate:o).The BT sounds interesting,last year I had my first border atack the black beauty was the first one to go and the least tasty so I didn't care by the time they got to the yellow squash it had 6 female bloosoms that I manage to harvest by doing surgery and bury the steam,then just pulled the plant.

I posted just the other day on the method I am currently using with good success. Look for my post in this forum titled: "I'm winning the battle with svb - for now." I will try to post a link below. It outlines basic steps.
