K., I use Diatomaceous Earth for insects (including roly polies) around my hostas. I would think you could sprinkle some around your door jamb and deter them. It's made with tiny bits of rock (a simple explanation) that cuts their bodies when they crawl across it. I put mine in an old spice jar that has the holes on top, and just sprinkle it where I need it. When you are handling it, don't get it close enough to your face to breathe it in. You can get it at some garden centers and online. (It's not the kind you use in swimming pools.) I also read somewhere that ants will not cross a chalk line - maybe that applies to roly polies as well. I've not tried it for roly polies, but a chalk line around a pet food bowl will keep the ants away.
