There are thousands of species of fire ants in the world. Fire ants live in underground tunnels. This is also where they find most of their food. Fire ants do not eat solid food, which can make them very difficult to eradicate. Although some people do keep fire ants in captivity, usually for research purposes, to most people, fire ants are considered vicious nuisances.
Fire ants can spread very quickly.
The two imported varieties of fire ants are far more dangerous then the native breeds. Therefore, it is important to attempt to spare the native breeds as they keep the imports from spreading. Fire ants can spread at a great rate and are quite able of reinfesting areas in which they had been eradicated. The reason they can spread so quickly is that they can fly and can drop into a new area. Fire ants breed between 600 and 800 feet in the air.
