what bees build nests
In any event, mostly it is not necessary - more about that in a moment. Bees nests, depending on the type of bees, vary greatly. Bumblebees like to make their nests in tussocks of grass or in abandoned rodent holes.
These man-made structures are typically referred to as beehives. Several species of Apis live in hives, but only the western honey bee (Apis mellifera) and the eastern honey bee (Apis cerana) are domesticated by humans. A natural beehive is comparable to a bird's nest built with a purpose to protect the dweller. The beehive's internal structure is a densely packed group of hexagonal cells made of beeswax, called a honeycomb. The bees use the cells to store food (honey and pollen) and to house the brood (eggs, larvae, and pupae).
