If you’ve never been attacked by Fire Ants consider yourself very fortunate. I was clueless that we even had fire ants in Tennessee until 4 or 5 years ago. Reached down to pick up a large rock I use as a wheel chock for our flatbed trailer and suddenly my hand was covered in tiny ants. I wasn’t immediately concerned, thinking they were just normal ants and started to flick them off my hard when suddenly my whole hand felt like it was on fire, stinging, burning and incredible pain at the same time. I couldn’t get those suckers off my hand fast enough. My whole hand swelled up and I got big sores where I’d been stung (they have stingers like wasps and mandibles to bite, so they get you two ways) and it took forever for the stings to heal.
I’ve got that Amdro on my list for the next run to Lowe’s or Home Depot. 2 of mine aren’t allowed in their pasture right now as the grass comes in, so its a good time to treat with the Amdro and see if it works. Oddly, the fire ants have never invaded the 1/2 acre paddock where those two are now.
