At night something is munching on our bean and zucchini leaves. They are
nibblers cause it takes several nights to chew up one tiny leaf. Anyone have
any idea what it is? Do mice eat veggies? Are ants vegetarian. I have
circled the plants with salt and ant poison so far but would love to hear
from anyone that has any idea what might be eating our veggies, its very
discouraging here in extreme southern California. Thanks for any help.

I'd suspect earwigs, if you haven't seen any beetles hanging about
during the day. They tend to tatter young growth.

Voles (mouse-like rodents) will eat vegetables, but usually clip off entire leaves
and blossoms at once, not slowly nibble away at them.
