Are pill bugs bad for the garden and how can they be controlled?

Pill bugs, also known as roly-polies, are not necessarily bad for the garden as they help break down decaying plant matter. However, they can become a nuisance if their population grows too large and they start feeding on young plants. To control pill bugs in the garden, you can reduce moisture levels, remove debris where they hide, and use barriers like diatomaceous earth or copper tape to keep them away from vulnerable plants.
