Something major has changed in the structure & is causing this behavior change. Weather change, possible contamination, food supply drying-up, something is throwing the colony into disarray.... Could be a problem with the Queen - She may have died without leaving a successor....

Good. Maybe they will eat themselves out of your property. I don't see a problem

The colony is becoming increasingly disruptive. I noticed yesterday a warrior ant savagely attacking a worker ant of the same colony. Other warriors wanted to join in but the warrior chased them away and continued. Other time I saw a warrior eating a worker alive also. Today I picked up a warrior and he bit me with his mandibels, odd as they are usually not aggressive. These ants are large like carpenter ants but unlike carpenters they primarily eat meats. Why is the colony becoming so disruptive. Ps: they are free-range ants found in my home.
