Striped Ants had a habit of paralyzing their prey with the paralyzing venom they had, and then bringing them alive to their queen.
This didn't mean that they wouldn't occasionally kill their prey to eat, it was just that stockpiling food was something that they generally did.
For this reason, many low-level origin masters tend to fear them as the combination of those two can be dreadful.
Origin beasts that entered the Striped Ants' nest would get paralyzed by the ants and then taken to the queen's chamber where they would then be enslaved by the Spider Queen.
So they weren't stockpiling food, they were instead increasing the Spider Queen's army.
Moreover, as the size of the army increased, the Striped Ants would also increase the size of the lair.
The size of the ant nest would get progressively bigger and as it grew in size, the number of monsters it attracted would also grow, creating a vicious cycle.
