I have a friend who has bamboo in his back yard. He talks about keeping it under control by going out every year and using a long narrow "sharp shooter" shovel to slice down into the tubers or runners or whatever the rhizome roots are called that let it spread.

This is the time of year to shift my sleeping schedule so I can get up earlier in the morning for yard work. It's too hot to do much from midday on. I may mow the back for a while after the worst of the heat has passed and before the mosquitoes are out. It sometimes takes a couple of days to finish one of the yards when it's really hot.
