I believe it was about 50years ago when they arrived in Florida. The fish & game folks tried to get us hunters interested in them as a food animal but that didn't go over well. F & G even put on a few Armadillo BBQs.
They are destructive to our pastures & yards and we shoot them here on the ranch but can't kill them all. They move in to replace their fallen brothers. Same with the hogs. If we don't keep them thinned out they just overrun the place.
There tough, I remember one night driving up to our hunting lease. I was following my friend in his new Datsun pickup in my ford pickup. A diller ran across the highway and his front tires missed it but one rear tire centered it. That thing came out from under his tire running and jumping higher than his pickup onto the roadside. From my vantage point right behind he appeared unharmed.
