I've tried two different brands of sprinkle-on-the-mound chemical granule products. The mound will die off but a new one comes in about 4 feet away shortly thereafter. I would seriously like to quit chasing them around my yard and get them gone. Is this possible? What is your experience? (FYI -- I found out quite by accident that if you put a thin layer of Vick's vapor rub on fire ant bites the day it happens ---- it takes the sting, hurt and "itch" out of them)
