Pharaoh ant new nest is formed, queens are not a necessity; workers can raise new queens after finding a suitable nest site. In pharaoh ant colonies new males and queen ants can be produced when the existing fertile queen is removed. When queens are absent, the workers in the nest can do two things: either rear existing sexual larvae or transport sexual larvae from other bud nests or from the main nest to its own nest. However, when there are fertile queens still within the nest, the worker ants will cannibalize the sexual larvae and will either reject or consume sexual larvae
Ant from other social insects including other ants. Some species specialise in preying on termites ("Megaponera" and "Termitopone") while a few Cerapachyinae prey on other ants. Some termites, including "Nasutitermes corniger", form associations with certain ant species to keep away predatory ant species. The tropical wasp "Mischocyttarus drewseni" coats the pedicel of its nest with an ant-repellent chemical. It is suggested that many tropical wasps may build their nests in trees and cover them to protect themselves from ants. Other wasps, such as "A. multipicta", defend against ants by blasting them off the nest with bursts of wing buzzing. Stingless bees
