Here is a Fire Ant. You can see its head, it has choppers. We have 'em too, I use a service, has to spray about every 30 months. More active in wet weather. To have some fun with ants, just go to a pile of them, take a cup of that pile of ants, put it on a pile of ants about 10 or 20' away. They will destroy each other, it is total war.
