Probably hitched a ride on an illegal alien bedroll or backpack.
Chocolate covered fire ants, now with extra formic acid
This reminds me of a recent occurrence... A friend of my brother’s had just retired from his job of 35 yrs or so. He was in his first few weeks of retirement and he went golfing. Well, he hit his drive into a deep rough spot, he found his ball and was taking some time to hit it. By the time he was ready to hit he started feeling fire ant bites all over his legs, they are very painful. Sad to say he had a heart attack right then and there and died.
Fire ants suck.
