What happens if you kill the ant queen?
If a queen were to die, there would be no one to replace her (female worker ants cannot reproduce) and the colony will eventually die out. It won’t be an immediate end to the colony, but eventually, the population will slowly dwindle and die out since there is no queen to replace her lost numbers.
