The relationships between the queen and the breeding males may last for many years. "Reproductive suppression" causes the other females not to reproduce: the infertility in the working females is only temporary, and not genetic. Queens live from 13 to 18 years, and are extremely hostile to other females behaving like queens, or producing hormones for becoming queens. When the queen dies, another female takes her place, sometimes after a violent struggle with her competitors.
