If it's damage during the day, then I'd guess squirrels. But if it's at
night the it's probably mice or dare I say rats.

I'm finally getting a few ripe tomatoes after a cool, rainy
summer but every tomato that's ripened so far has holes
eaten in it. Today I found the culprits - it seems to be
sowbugs munching the holes. Does anyone have a suggestion
to preserve my remaining crop?? Thanks for any help.

the sowbugs are opportunists, not the culprit. holes in
tomatoes could be : tomato hornworm, chipmunks, squirrels,
slugs, mice, voles...
go look at the tomatoes at night & see if there are slugs.
cool, rainy summers are slug heaven.
