it is very difficult to get rid of
You have to keep cutting any new shoots off as soon as they appear.
Keep doing this until no more shoots come up. This exhausts the energy stored in the rhizomes underground. Without green leaves to photosynthesize and produce new energy, they will no longer be able to send up new shoots. The rhizomes will be left behind, but will rot away.
Sometimes it can come up in your neighbours garden the rhizomes travel undergroud away from the plant and come up somewhere else, you can dig up, but if you break the rhizome or leave any behind they will keep reappearing.
We had to get a digger in and excavate a very large hole and then burn the plants, then turfed the area and now because it is regularly mowed there has not been a sign of bamboo for a while - we are hoping it works. The other way is to paint the cut off pieces with roundup which should also kill the rhizomes, but I would think would need doing a few times.
