I was digging in my vegetable patch and came across some works which I
believe to be cranefly larvae. What should I do/use to get rid of them?

The safest thing to use in a vegetable garden would be beneficial (insect
predatory) nematodes. Tilling will destroy, bury too deeply, or expose them
to birds and effectively control them.

In a lawn, you could use a systemic insecticide but that wouldn't be appropriate
in a garden.
