Each of these mounds are estimated to have a population ranging from 100,000 to over one million and there can be dozens of them within a 100m × 100m square. I imagine it similar to the state of New York full of NYCs, just a few miles between each. A Finnish study found that these mounds can be connected into super-colonies which span kilometers. [1]
I have also lived in California and have experienced red ants beginning to stake out territory near or in my home. Remember that they are not there just because of the food sources, but in spite of us making the terrain otherwise utterly inhospitable to them with pavement, insecticide, diatomaceous earth, and all of that. And still they can be incredibly difficult to get rid of.
The way they operate as a colony makes them very interesting. I can see why so many people have caught the ant-fascination bug.
They're interesting semi-aliens because the colonies are incredibly capable in many respects but ultimately lack self-awareness, which leaves the ants open to manipulation by other uplifted species that are capable of motivated planning. The ants become like biological technology for the other species.
That reminds me of Phase IV. It's like an alien invasion movie, but with ants instead: https://www.imdb.com/title/tt0070531/
It does make one think of the sustainability of that situation however.
So you can think of it as a single organism that has a "distributed" body.
From that perspective, the individual ants correspond to cells or organs, and it becomes both less and more fantastic :)
When Tim Gallaudet says "advanced non human intelligence" are interacting with our assets in the oceans - I doubt he means dolphins.
Tho both are undoubtedly NHI.
The actual "tech civilizational level" NHI are often described as insectoid. Interesting to consider that a collectively intelligent ant species could proceed through evolution into a multiplanet technologically super-advanced one.
If I were ant emperor I’d attack human farms and food processing places.
I sort of recall some ant experiments going to the ISS, but are they still there?
All spacecraft that I know of are well-cleaned before launch, and there's not much for food sources, but have any gotten into a survivable location on an inhabited module?

All of them.
