Foundation is installed into frames within the hive, and bees use it as a template to construct honeycomb cells. By providing a pre-made structure, the foundation helps bees build straight, uniform comb, which makes hive management and honey extraction easier for beekeepers. Additionally, the foundation helps prevent bees from building comb in undesirable locations within the hive, such as between frames or on hive walls. Overall, the foundation plays a crucial role in maintaining the organization and productivity of a bee colony.
