They are called Pill bugs and are generally harmless. They eat dead vegitation i.e. your grass. You can use insecticides but it's not necessary. They like wet areas with dead vegitation. When the grass comes back they will be less noticable. I know people are treating for the fungus that is killing some of the zoysia. The bugs are not killing the grass.
I have just raked some of the dead grass added scotts funguscide plus fertilizer and new grass is creeping back in. I don't know if you really have to do much else.
I really think it is a problem caused by the harsh winter and dry spring. But this zoysia is very tough stuff and with all the recent rain is coming back fast.
I am no landscaper just like to do my own yard. I may be wrong.
