Meat ant of the colony may deteriorate from overshadowing. Members of an affected meat ant colony later move to a nearby satellite nest that is placed in a suitable area, while invading banded sugar ants fill nest galleries up with a black resinous material. Meat ants sometimes attract cats because of the chemicals they secrete (dihydronepetalactone, isodihydronepetalactone and iridomyrmecin). Meat ants are generally intolerant of myrmecophiles (which are insects or other organisms that share positive interspecies associations with ants) living in their colonies, but "Cyclotorna" larvae are known to dwell in colonies. Although "Sphallomorpha" larvae sometimes prey on workers as discussed earlier,
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.
