The "fire ant" part of their name refers to the burning sensation you feel when you get stung, especially by several ants at once. With most people, the immediate burning sensation goes away in a few minutes. A day or so later, the fire ant's unique venom forms a white fluid-filled pustule, or blister, at the sting site.
The word "imported" in the approved common names of the species was probably a poor choice, because "imported" typically suggests that the ants were brought here on purpose. On the contrary, imported fire ants were accidentally introduced into the U.S. via trade ships traveling from South America, their native home, into the Port of Mobile, Alabama.
There are two species of imported fire ant in North America, the Black Imported Fire Ant arrived around 1918, while the Red Imported Fire Ant arrived around 1930. Since their arrival they have spread rapidly throughout the Southeastern U.S. and into parts of Texas, Oklahoma, New Mexico and California.
For the latest distribution of imported fire ants, please look at the APHIS USDA - U.S. quarantine map.
