Well I finally managed to check my sweet potato vines out at night....and no slugs or snails or any evidence of their existence. But lots of pill bugs, some ants, and a cockroach were amongst the vines.
When we bought this house back in August of last year we had a cockroach infestation and didn't know it til we were moving in at night time! It was awful and oh so disgusting. We stopped moving in and fought them hard. We used foggers, sprayers, gels, etc and we finally managed to rid the house of them. Then moved in and got through fall and winter.
In the past few months we've been finding the (increasingly) occasional dead/dying roach in the garage and the rare one in the house. Going to definitely fog the house again soon.
Anyways, when I was outside checking the vines I caught a live one right at the roots of my Bougainvillea which is situated right around the vines. Killed it with my bug sprayer, then proceeded to check the rest of my plants just out of curiosity. Found about 10 or so roaches amongst my plants and in the grass.

EWWWWW! I sprayed the crap out of them without regards to my plants. Hopefully I didn't damage them too bad.....but roaches just plain have to die! So, my question is, do some cockroaches eat plants? I'm fairly certain these are the Smokey Brown Cockroaches due to their size (huge!) and dark color. I have the hebbie gebbies now just thinking about them. Yuckity-Yuck! I WILL buy foggers tomorrow. Must do! EWWW! Sorry if I grossed anyone out....I know I don't like to hear about bugs especially roaches.
