Ants in Compost?

I have a mature compost pile which I plan to use in my garden next spring. This morning I turned it and noticed two things:

1. It has pretty much completely turned back into rich, black soil, except for a few bits of "brown" material (e.g. some coco fiber, a few cardboard egg cartons)
2. When I turned it, a million ants started scrambling all over the place.

Is it possible that I have an ant colony nesting in my compost pile? If so, should my reaction be good, bad, or indifferent? And if I want to get rid of the ants, how do I do it without damaging the organisms that I want in my compost?

So I read on another site that ant activity is a sign of a dry compost pile. I took my hose out to the bin and started spraying. Since this is my first foray into composting, I had no idea how thirsty a mature compost pile can be. My small pile (abt. 4x5 ft. & 18 inches high) just soaked up about 30 gallons of water without a burp.

Hey, everyone. Did you know that if you scroll down just a bit in this forum, you'll find a thread that answers this exact question? Cool, isn't it?

Yeah. There's an feature built-in that picks up key words, and then searches other threads to see if it can match them.
Usually it will point to similar threads. Handy feature for finding related info on the subject.

Argentine ants love to nest in leaf litter and that's probably what you have. Argentine ants don't bother me. They don't sting.
