Garden Pests and Diseases: Something is eating my snow pea seedlings, 0 by switt

I can't get my snow peas to start this year. As soon as the seeds sprout and come through the dirt, something is eating the tops of of them. Then they just die. I believe it's happening at night, because I haven't actually seen bugs on the seedlings. All of the veggie plants I bought are fine.

I know I have some ants and cockroaches outside. Would they be the cause? How do I replant my crop and not have this happen again?

Thanks for any advice you have!
