I am trying to determine what type of bamboo is in my yard - there are thousands of bees swarming it!? - bamboo privacy fence

We have just bought a house and the owner was with a bamboo fence at the side of the privacy of home. Until recently, there were no flowers, but the days were very hot and lumpy green flowers produced from the leaves to attract the thousands of bees and insects. I'm trying to understand is what kind of bamboo, so I know how to properly care for him. I've heard, reduce the former owners of bamboo to the trunk before the snow comes in October or November.
