In general, any time one brings a new plant on their property, they risk bringing in critters or pathogens with it. In the case of greenhouse propagated material, which would probably include sasa and indocalamus in your region, one should be on the lookout for infestation. You can inspect or ask for assurances that the vendor you are buying from is clean. In the case of box store and retail places, the people working there will not have a clue. If you buy from a real nursery, hopefully they know the condition of their product and are honest.
Dependable - I always check things thoroughly and treat appropriately even if I have only a suspicion. I guess my question is really how widespread this mite problem is in the USA. Has it reached the midwest or eastern USA? And do they persist on outdoor bamboos from year to year in the northeast? With the chains bringing in bamboos from sources which may be dubious and gardeners importing from all over and unaware of the hazards this could be a ticking time-bomb.
One of the books mentions birds as being a vector for mites from garden to garden and they certainly love to hang out in bamboos.
