I am having a ton of those rolli polli potatoes bugs in my raised bed...
What you refer to as rolli polli potato bugs are most likely pillbugs or sowbugs. They are not harmful and will not damage the plants in your vegetable garden. They are decomposers and feed on decaying material in a garden. A thorough garden clean-up should help reduce their numbers.
