All about Podded Peas

With  snap peas do you still get pea moth grubs? If so, how do you know if you eat the  snaps whole?

I sow peas early so they finish early, mostly before the pea moth arrives. Frees up the bed space by late June so can I get something else in there (last year it was savoy cabbage, the year before that carrots). By the time the peas are done I'm sick of them anyway, and it's not long before the French beans start cropping.
