'Crazy ants' terrorizing parts of U.S. are resistant to chemicals that kill other species | Mail Online: "A new and annoying species of ant is terrorizing the U.S. and chemicals that kill off other types of the insect are proving ineffective against it.



The 'crazy' ant, named for the erratic trail it leaves as it makes its way across the country, originated in Argentina and Brazil. But since it was first spotted in Houston in 2002, it has spread to some 21 counties in Texas, 20 counties in Florida and a few locations in Mississippi and Louisiana."
