My daughter and I were travelling across the southern states from San Diego on our way to her college in Savannah, Ga. We stopped off at my brother's place in the suburbs of Dallas for an ovenight, and we had left one doughnut in a tightly closed bag on the back seat of her VW bug. The next morning the trail was evident, up over the front tire thru the suspension holes and into the car. She was barefoot and didn't notice the ant trail till it was too late, we wound up going to the hospital for treatment.
Later that day I watched as one of the apartment complex's maint. guys came out to poison the hill. He had on thick rubber boots and one of those pump up sprayers, as he stuck the nozzle down into the hole and started spraying they came boiling up out of the mound, he calmly pulled the wand back and sprayed them off his boots then went at 'em again till he emptied his bottle. I now have a very healthy respect for those critters!
Glad the little guy is OK, hope he learned his lesson!
