I will admit that this thread has been a bit confusing to me. I believe I refer to your rollie pollies as potato bugs, and when I do an internet search for rollie pollie that is the critter I am talking about. I also searched for potato bug and came up with some weird looking thing I've never seen. So it must be a regional thing. And Zuzu refers to them as a local monster, which mystifies me, as I've never thought of them as anything other than a fun bug for kids to play with. Again, must be regional. Whatever damage the rollie pollie/potato bugs might do in the Pacific NW is likely so overshadowed by slug damage that it is inconsequential. (Just my guess, I'm no bug expert.)
