Fire Ants Kill Winter Texan in the RGV

Amdro works well. It takes time to do its job. The ants carry it into the nest and feed it to the queen. If you are expecting instant annihilation like spraying Raid on a roach, that isn't gonna happen. Some people are having good results with diatomaceous earth. Supposedly, it slices their skin and causes them to die of dehydration. I say the best defense is just watching your feet. Fire ants don't just hang out in obvious mounds. If you see an ant on your shoe, move. (And by the way, jumping in the water does not cause them to let go. I have even tried to hose them off my kids when they've gotten into them. They just hold on.)
