Banded sugar ant colony can be long-lived, with queens living for seven years or more. The black carpenter ant ("Camponotus pennsylvanicus") is known to adopt larvae and pupae from banded sugar ant colonies. Workers that belong to different matrilines (female ancestry) appear significantly different from each other in size. Matrilines are also said to influence caste determination within the species. The banded sugar ant is considered a household pest and is occasionally seen in houses at night, capable of damaging furniture and fittings by chewing the wood; carbon disulphide is used to treat and remove a banded sugar ant nest. These ants do
Red harvester ant the nest as a result of an increase in successful returning foragers. Relative abundance of food available is gauged by the average time spent foraging per seed, rather than the distance traveled to find each seed. Foragers take less time when food is more abundant. Faster foraging signals faster rates of outgoing foragers, maximizing the harvest of food relative to the abundance in the area. Seeds are used as a source of water for ants, and are often kept in the nest for a few months to several years. Interspecies competition exists between harvester ant populations, presenting challenges to successful
