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,
Leafcutter ant virulent fungus, has the potential to devastate an ant garden, as it is horizontally transmitted. "Escovopsis" was cultured, during colony foundation, in 6.6% of colonies. However, in one- to two-year-old colonies, almost 60% had "Escovopsis" growing in the fungal garden. In some parts of their range, leafcutter ants can be a serious agricultural pest, defoliating crops and damaging roads and farmland with their nest-making activities. For example, some "Atta" species are capable of defoliating an entire citrus tree in less than 24 hours. A promising approach to deterring attacks of the leafcutter ant "Acromyrmex lobicornis" on crops has been demonstrated.
