I first saw these "loco nano maras" in Guatemala City during my 2007 Navidad-New Years visit. Here in the USA, they are no longer limited to the Houston region. We have an infestation here in Donna, Texas - Valley of the Rio Grande. My gut impression is that these creatures have nothing in common with other earth insects, that they actually are some sort of genetic DNA experiment gone wrong or indeed a creation of nano technology hence the electronics connection. Yes, I know that sounds as crazy as the crazy ants themselves but who really knows what sort of little monsters are being created in science labs? As far as eliminating them, I suggest that a counter-electronic solution may be the best bet. I called Riddex Plus to learn if their electromagnetic pest elimination system also causes the Rasberry Nano-Ants to vacate houses but of course, was unable to speak to a bona fide human being... merely female-voiced computers. Why don't we use the computer-eating ants to permanently eliminate such annoying (lack of) communication systems?
