My guess is slugs. Since the evidence is on more than one plant. And, they generally come out at night to feed/destroy on your plants. I have 4ft wide and tall hostas in a part shade bed. # years agoI started using the droppings from the old spruce tree (needles and pokey twigs) under my Hostas and to date I haven't had as much as a nibble on any of my 7 Hostas.

Interesting. I have a row of white pines, so there's plenty of defensive material for me to scoop up. I'd just lay a bed of needles around the pots?

And while I appreciate the feedback, I'm a little skeptical of it being slugs. I'm not sure how they'd reach those leaves. What you're looking at there is a couple of feet off the ground (wood porch steps, technically) and I've never seen slug trails back there.

The edges of the basil look like it might be a grasshopper. I don’t know about the hole tho’.

Slugs, and even more so snails, can climb. I sometimes find snails on window sills four storeys up.

I agree that the basil damage doesn't look like gastropods but the sweet potato holes do. Check at night and check under the pots.

"I've only seen wasps around them here and there, but I didn't think they munched on this stuff. "

No, wasps can feed on fruit and nectar, but not on the plant foliage.

Yes.

Slugs can climb on nearly anything.

Go out in the evening with a flashlight. You will likely catch the villain. Also look on the under side of the leaves.
