Looks like there is more than one type of these tiny, crazy invaders. It seems both have entered the US through the ports. Both are heading to Alabama.
Longhorn Crazy Ant = Paratrechina longicorni; originated (probably) in Southeast Asia.
This link from a Savannah Newspaper has a video; Tawny Crazy Ant = Nylanderia fulva = Rasberry Crazy Ant; first found by an exterminator whose surname is Rasberry. (What a way to get famous!)

This link from BugGuide talks about both types.

Researching this will keep me busy for quite a while! How confusing; the one from Texas is called Rasberry and the one from Asia is called Longhorn, hmmm. I always think of Texas Longhorns. I'm already dyslexic; this is too much for my wee brain.
