How can I get rid of the rolli pollies that keep eating my plants?

I have an infestation it seems of rolly pollies in
my yard that keep eating any type of hedge I try to plant. I've tried the wet newspaper trick, beer in a tuna can buried in the soil, manually picked them out one at a time and have elevated and removed all debris from under and around the plants to no avail. I'm about ready to give up! is there any type of spray or garden repellent I can use to get rud of them?
