If you don't want to search for a bee nest, try spawning one yourself! To do this, you will need saplings, flowers, and bonemeal.

You spawn bee nests yourself by planting saplings near flowers. A sapling will have a 5% chance to spawn a bee nest if it is grown within 2 blocks of a flower. You can speed up the tree's growth by using bonemeal.

This may take a while. However, it is helpful if you are not near an environment where bees will spawn. Bee nests spawned from saplings will hold 1 to 3 bees.
