Prenolepis compete with other ants by being active in far colder conditions. I think they can just survive Argentines because of this. It’s not so much that they’re fighting them back or something.
Actually studies show their chemical defenses freak the heck out of Argentine ants.
This was a great article, though I believe I had to go back and read more of the original literature. It does have cool videos.
