I don't have any personal experience, but a quick google search of the words "bamboo termites" turned up the following information:

1) Termites do eat bamboo.
2) Some bamboo species seem to be more resistant than others.
3) Not all species of bamboo make good building material.
4) Fungus, powder beetles and woodworms are also problems.
5) There are a number of ways to treat bamboo in order to insect-proof it.
6) There is actually a species known as the bamboo termite (which should give you a clue right there) that is apparently very tasty if you like that sort of thing-- and there seem to be enough people who do to support a restaurant featuring insect cuisine. Think I'll take a pass on that one...

Didn't come across anything specifically on flooring, but then I didn't really look that hard. This site gives a lot of info on harvesting and treating commercial bamboo:
