Because Grendel, the evil monster, only killed at the night in the shadows
Grendel attacks and kills thirty of the Danes while they are sleeping in Heorot on their first night back.
Yes, in the book Beowulf, the Geats did not build Herot. Herot was a mead hall built by the Danes to celebrate their victories and as a place for feasting and social gatherings.

Grendel attacks Herot because he is envious of the happiness and joy he sees in the warriors' hall. As a being cursed to live a life of isolation and misery, Grendel is filled with resentment towards the humans who celebrate and enjoy their lives in Herot. His attacks are driven by this deep sense of anger and alienation.
grendel attacks the people who are in it by "the moon" (at night)
Grendel hates Herot because it is a symbol of human joy, celebration, and community - everything he is excluded from. The noise and revelry of the mead hall highlights his own loneliness and isolation as a monstrous outcast. Grendel's jealousy and anger towards the humans grows as he sees them enjoying the very things he can never have.
After the feast at Herot, Grendel attacks the warriors in the hall at night, killing many of them. This cycle of attack and retaliation continues until Beowulf arrives to defeat Grendel.
King Hrothgar of the Danes, whose hall, Herot, is raided nightly by Grendel for twelve years before Beowulf killed the beast.
Herot is the mead-hall of King Hrothgar, where his warriors gather to feast and celebrate. It is described as a grand and majestic hall built as a symbol of power and wealth. Herot plays a central role in the story of Beowulf as the setting for the battles against the monster Grendel and his mother.
While Beowulf fights Grendel in Herot, a mead hall owned by Hrothgar (king of the Danes), he fights Grendel's mother in her underwater castle in a nearby lake.
