Meat ant within a colony is typically favoured as it improves access to forage, as workers deliver most of their food to the nest that is closest to any site they forage in. At any size, a meat ant nest always has a possibility of dying out in any year, but the site may be reoccupied by another colony. Hence, nests can be very old as suggested in one study. Some nests may never be reoccupied for unknown reasons. The regrowth of vegetation which shades the nest, soil damage or even a disease may wipe out a colony and leave the nest
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
