Fire ants!!,I live in east Texas and this has been one of the worst years to date.Most folks have a house note,and a truck note,we have a "Amdro" note,trying to keep them away from the house.I've got scars on my legs from all the bites through 51 years of the little red devils.We've even got a name for the panic'd, explosive rush to get shed of the pests,"the fire ant dance",and we're all pretty good at it!!Several have mentioned how they all wait to sting at the same time,well,if you've got real good hearing,and listen real close,you can hear the leader countin', 1,2,and 3,NOW!!! I train horses,and I have to be particular about where I stop,(while working a young horse).If enough ants get on a colts leg,it can get pretty western if you let your guard down.Just think,Noah had just 2 of them on the ark,and all it would have taken was one mis -step. God Bless
