Bamboo is a nightmare, and some cities and counties are finally realizing this and banning the planting of it. In the meantime, somebody recently posted in the Tree forum about it, and here's the link. I'm afraid it's RoundUp and a couple of years, but the alternative is worse. Good luck.

Here is a link that might be useful: recent thread on getting rid of bamboo
