Ant eggs in the ant hill. Can confirm that for sure. They are actually in 2 different locations inside the ant hill. One spot for sure is at the right around the hole that you can drop down into. Showed ant eggs a few times in one of my streams. If they aren’t there for you maybe they all hatched already and youll probably have to keep checking. It might help to kill some of the soldier ants because there are alot in there and I’m not sure if they could be blocking the spawn points of eggs.
Wear full ant armor for the HumAnt buff so they won’t attack you on site. They will still fight back if you attack though.
