The problem of fire ants in the US is really actual. According to National Geographic and Discovery channels, several types of chemical, biochemical, biological approaches have been employed in the fight against fire ants. Recently, scientists have started investigating the possibility of using other ants that can chase, kill and eliminate these fire ants.
This fire ant is the soldier ant which is also native to the tropical rain forest of Nigeria. To chase, kill or eliminate this ant is really done with the aid of another ant called the sugar ant. The sugar ant is harmless to humans (and their properties), but attracted to sugar cane shafts, lumps and granules. It is not attracted to natural honey (except where the honey is adulterated with sugar). The average sugar ant is almost 20 times smaller than the average fire ant, but for whatever reasons (scientists need to investigate further), a colony of fire ants will never stand the invasion of just 5-10 sugar ants!
This may be the most desired solution to the problem of fire ants in the southern part of the US.
