Pill bugs & sow bugs are generally harmless, there's rarely any need to control them....

Here is a link that might be useful: Pillbugs, sowbugs, etc.

I agree with Carol that they are generally harmless because they eat decaying plant matter. However, they will sometimes they eat seedlings. But they can only eat the tiny, very tender seedlings.

They ate all but one of my amaranth seedlings, some African daisy seedlings, and some marigold seedlings. (Yes, I saw them feeding.) In the same bed with the amaranth, they didn't touch the cilantro. I don't know if the cilantro was too fibrous or just not tasty to pill bugs. As soon my one remaining amaranth seedling grew some true leaves, they left it alone.

I traded the plant with someone and I don't want to infest her house with them. I don't know when she is going to pick it up.

As the UF EDIS pub. says, they need moisture to live - perhaps if you let the plant dry out, they'll move away?
