That is great, you have a much bigger variety of things than I do.
I have been thinking about a fall crop but honestly I am not sure
I could take the disappointment. I have never really had any luck
with a second round of squash. SO I may just wait until later and
re plant some cabbage, lettuce and sugar peas. Question? Will the
borers stick around? The plants will all come out and I will re-till
the dirt but is that enough?

Squash vine borers are moth caterpillers, and the eggs are laid
directly on/in the vine. So if you are worrying about more of them
in the soil, that isn't a problem. Of course, they may still have
a nearby population, so there is no guarantee.

I don't grow much that is bothered by them (though I have some acorn
squash in this year), but the best thing I've heard is to use row
covers. If the adults can't get to the vines, they can't lay eggs
there.

Squash borers have a pupa that overwinters in the ground . To quote :"
Beginning in late June or early July, squash vine borer adults emerge from
cocoons in the ground. Squash vine borer adults are good fliers for moths
...."
Tilling helps destroy the coccoon , and is one method of control . Watch
the underside of the leaves for their eggs starting in late May/early June .
They'll be clusters of small orange/yellow balls that squish easily . Each
egg can potentially cost you a vine ... I was lucky this year , I never
found any eggs on my vines to destroy .
