there are very big ants called bulldog ants they can kill people they live about a year max maybe you can buy the antworks on the internet (type in on google) and find out yourselve.
Queen ants live 5-15 years, depending on species.
The other ants in the nest - workers, guards etc may only live for weeks or months.
Interesting question, I did not know that!
An ant can live, at a maximun, to 2 years. Considering their size thats pretty good. Hope I helped!
