You sure it isn't pinned? If done well the pins can be extremely hard to see. Many Bamboo builders use something like a Philobond (contact cement) to set the ferrules. Heat works with many of the cements, even epoxies. Just like with any other component removal too much heat is a bad thing, but Bamboo is a bit more forgiving. Lighter or alcohol burner will work well since it is a localized heat.
FYI: Bamboo is a grass, not a wood
