To be honest, my experience of removing bamboo is very different to Nick Fareham's. I had a clump about 8' long and 3' wide. It had been well behaved for years but went 'rogue' due to events I won't repeat here as I've described them previously.
To remove it I cut the majority of the canes to ground level but left a number of thicker ones so that they could be used as levers when removing clumps. I then used a pick to dig a trench all around, which also exposed any runners heading off into the wide, blue yonder. I cut through the runners and also divided the main clump into sections to make removal easier. Again using the pick I dug under each section to loosen it then rocked it back and forth to remove. Repeated that with each section until is was all gone.
Final stage was to trace the route taken by each runner by pulling gently but firmly up and cutting above it where it was running through the lawn. That also enabled me to spot any other runners setting off from the main stem. That was done 3 years ago and I haven't seen any sign of bamboo since.
It was time consuming but not particularly difficulty. The bamboo in question was Phyllostachys Aurea.
