Robert's field note · Fire Ants
“Flooding or kicking a fire ant mound just moves the queen ten feet over. A real program treats the whole yard with a bait the workers carry back to her, then hits the mounds that matter most. On acreage in Medina County, we plan around where people and animals actually walk.”
