It’s my understanding that roly poly bugs tend to be more interested in eating plant matter that has already begun to decay. They are contributing to the healthy composting process naturally happening in your garden. If you notice them in an area you want them to vacate, make sure the area is kept tidy and free from all dead/dying plant material.
I’m more bothered by other bugs like the squash vine borer, cucumber beetle and cabbage loper. Roly poly bugs aren’t a big deal to me, except in my strawberry patch. I wouldn’t worry about any pest unless it’s causing problems in your garden. Althought, once they are eating more of your harvest than you are I would start trying to find an organic method to bring about their swift demise. Spreading Diatomaceous Earth (DE) can help, but it needs to be reapplied frequently. DE is a white powder, it’s harmless to humans but it’s like broken shards of glass to bugs. They don’t do well when they crawl around in it.
I loved those roly poly bugs, aka pill bugs, when I was little. Now I just find them annoying. For the most part roly poly bugs are supposed to be good to have in your garden. They like to eat decaying debris so they are generally good for the health of your soil. This year though, they pretty much ate half of my strawberry produce so I wasn’t happy about that. I tried putting something under the ripening strawberries to keep them off the ground and that helped a little. Some people do this with straw to help keep the ripening fruit off the soil.
Roly poly bugs also like to hide under mulch or dry leaves so if you have a lot of that on the top of your soil and they seem to be damaging your plants, I would maybe rake the mulch up a little and they will go find a new hiding place. Otherwise, from my experience they eventually move on and don’t really do any longterm damage.
