Banded sugar ant meat ants, which have been observed blocking banded sugar ant nesting holes with pebbles and soil to prevent them from leaving their nest during the early hours of the day. The ants counter this by preventing meat ants from leaving their nest by blocking their nesting holes with debris, a behaviour known as nest-plugging. If meat ant nests are encroached by trees or other shade, banded sugar ants may invade and take over the nest, since the health of the colony may deteriorate from overshadowing. Members of an affected meat ant colony later move to a nearby satellite nest that
Meat ant chambers where the population remains during the winter. In the upper areas of the colony, the galleries and shafts only account for 7–10% of nest space. For example, the galleries of excavated colonies occupy whereas the total volume is around . Overall, a nest may dwell extremely deep beneath the soil as excavated nests are as deep as . A diurnal species (active mainly during the day), the meat ant shows minimal interaction with nocturnal ant species when their territories overlap. The meat ant and other members of the "I. purpureus" species group are regarded as a dominant group of
