Beehive
noun
ハチ is a bee. Buzz buzz. Just imagine "eight bees" combining into one bee, making it a "hachi." Then, there's a nest. What is a nest for bees? A beehive.

ハチのす
巣 is a standalone word here, so it uses the same reading that you learned when you learned the vocabulary.
ハチの巣の周りで沢山のハチがブンブン飛び回っている。
There are a lot of bees buzzing around the beehive.
