Try dynamite!! Seriously though, I have found that there are 2 types (and perhaps even more). There is the `clump` forming bamboo and the `spreading` bamboo. It is the second which is the problem. It can spread over large areas and as Verdun says, it is very difficult to get rid of. Use whatever weedkiller you can lay your hands on after digging out as much as possible.
The clump forming variety just needs all the roots digging out as it will not spread.
