I'm having the same problem with my beans--but not with the squash. Something has been nibbling holes in the beans and the pepper plants. For a while the peas were affected too, but the parts higher up the trellis don't seem to be. I have not actually seen any insects on the plants, so I'm not sure what's doing it. It seems like if it were slugs, they ought to be eating the lettuce and basil, which haven't been touched. I haven't seen any bean beetles or Japanese beetles anywhere in the yard, and I planted basil nearby, which is supposed to repel bean beetles. I've tried spraying the plants with a liquid soap mixture, but I'm not sure it's helping.
