Garden centers sell pill bug bait which attacks them and when consumed, the bait containining Sevin insecticide kills them. You can make your own bait using an organic insecticide in mushed-up bananas or any decaying food material. Some people put large lids or boards in the garden area and pour hot water on the pill bugs after they have congregated. You can co-exist by protecting young seedlings with a band of insecticidal dust which allows maturing of plants before devouring by bugs. The more organic matter you have, the more rollie pollies you will have.
Some gardeners recommend ducks or guineas.
My ficus has tiny brown pods on the stems and has a very sticky residue on its leaves. I have sprayed the ficus leaves and the soil with Sevin several times. This seems to help but does not solve the problem completely. I also have washed every leaf on the tree. Add two teaspoons of a liquid detergent such as Joy or Ivory Liquid.
