This is an example of the red imported fire ant. We've place some bait along the side; as you can see they're engaged in picking it up and carrying it down into their nest. They like to set nests up underneath, in the cracks of sidewalks, because the water kinda condenses in the crack and they're there for the moisture. We've been in a drought here in Texas so, as you can see, they're extremely aggressive. See? their attempting to bite my finger rolling all over me. Many of them are biting right now as I speak; I need to end that. This bait here is derived from a fungus that is found in the soil. It affects their entire colony but not immediately. They will carry it into the colony until the queen gets a hold of it then after a day or so the entire colony will die.
