Meat ant some are inquilines and live in the nest commensally. Unused or abandoned areas inside colonies are sometimes occupied by other species of ants and in some cases, termites. Meat ants may deliberately destroy the colonies of the termite "Amitermes laurensis" if competition between the two intensify. Meat ants play an important role in seed dispersal. A meat ant colony is capable of dispersing 334,000 individual bellyache bush seeds per hectare, which shows a strong ant-seed relationship among the two. Meat ants are able to kill poisonous cane toads, an introduced pest, as the toxins exuded by toad, that usually kill
Meat ant to gain access to water or where water has been spilt, either if the site is nearby their nest or far away. Despite their dominance among ants, a number of animals are known to prey on meat ants. The short-beaked echidna ("Tachyglossus aculeatus") is a prominent predator of the meat ant, mostly due to the high fat levels (up to 47%) in virgin queens. These queens can almost contain 47% fat, and when no queens are available after an attack, an echidna may stop attacking the nest. However, these ants are normally consumed either in low numbers or avoided entirely.
