At least this link has a pictuer of the eggs along with squash bug eggs.
As you can see they lay the eggs right at the base of the plant.
One way that helped me was to plant the squash at different places every year.
Many times this isn't practical.
One way to help is if you have an infestation done just let the vines sit there and die.
By that time the grub has moved out of the vine and back into the ground to pupate for next year.
Then the gardener comes along and plants more squash in the same spot for the cycle to begin all over again.
I have saved some squash by inspecting the vines every day and saw the little pile of droppings they leave as they bore in.
I would then take a knife and slit long ways with the vine and dig the grub out.
Another thing you can do is bury the vines so they can take root.
I hate the things.
Beautiful plant one day dead plant the next.
You have about a week to find those eggs.
