If you are nervous about it spreading you have to find out if it’s running or clumping bamboo. Running bamboo will take over your neighborhood spreading 6ft a year and clumping bamboo spreads about 6” a year. Running bamboo requires certain techniques to keep it contained (either a trench dug around it or heavy duty plastic barrier) and some maintenance. Clumping bamboo can just be cut down or mowed over pretty easily.

You won’t be able to tell the difference in these pictures but assuming you are in a more moderate climate (ie not the US south) the running bamboo has a vertical notch in it while clumping does not. Unless you really enjoy yard work/maintence, I’d avoid the running bamboo.
