Complex nests are built by many ant species, but other species are nomadic and do not build permanent structures. Ants may form subterranean nests or build them on trees. These nests may be found in the ground, under stones or logs, inside logs, hollow stems, or even acorns. The materials used for construction include soil and plant matter,<ref name = HolldoblerWilsonAnts2/> and ants carefully select their nest sites; ''Temnothorax albipennis'' will avoid sites with dead ants, as these may indicate the presence of pests or disease. They are quick to abandon established nests at the first sign of threats.<ref>{{cite journal | vauthors = Franks NR, Hooper J, Webb C, Dornhaus A | title = Tomb evaders: house-hunting hygiene in ants | journal =  Biology Letters| volume = 1 | issue = 2 | pages = 190–192 | date = June 2005 | pmid = 17148163 | pmc = 1626204 | doi = 10.1098/rsbl.2005.0302 }}</ref>

The [[army ant]]s of South America, such as the ''[[Eciton burchellii]]'' species, and the [[driver ant]]s of Africa do not build permanent nests, but instead, alternate between nomadism and stages where the workers form a temporary nest ([[bivouac (ants)|bivouac]]) from their own bodies, by holding each other together.<ref>Hölldobler & Wilson (1990), p. 573</ref>

[[Weaver ant]] (''Oecophylla'' spp.) workers build nests in trees by attaching leaves together, first pulling them together with bridges of workers and then inducing their larvae to produce silk as they are moved along the leaf edges. Similar forms of nest construction are seen in some species of ''[[Polyrhachis]]''.<ref>{{cite journal|vauthors=Robson SK, Kohout RJ |year=2005|title=Evolution of nest-weaving behaviour in arboreal nesting ants of the genus ''Polyrhachis'' Fr.

''[[Formica polyctena]]'', among other ant species, constructs nests that maintain a relatively constant interior temperature that aids in the development of larvae. The ants maintain the nest temperature by choosing the location, nest materials, controlling ventilation and maintaining the heat from solar radiation, worker activity and metabolism, and in some moist nests, microbial activity in the nest materials.<ref>{{cite journal| vauthors = Frouz J |title=The Effect of Nest Moisture on Daily Temperature Regime in the Nests of ''Formica polyctena'' Wood Ants|journal=Insectes Sociaux| volume=47 |issue=3|year=2000|pages=229–235|doi=10.1007/PL00001708|s2cid=955282}}</ref><ref>{{Cite journal|last1=Kadochová|first1=Štěpánka|last2=Frouz|first2=Jan|date=2013|title=Thermoregulation strategies in ants in comparison to other social insects, with a focus on red wood ants ( Formica rufa group)|journal=F1000Research|volume=2|page=280|doi=10.12688/f1000research.2-280.v2|issn=2046-1402|pmc=3962001|pmid=24715967 |doi-access=free }}</ref>

Some ant species, such as those that use natural cavities, can be opportunistic and make use of the controlled micro-climate provided inside human dwellings and other artificial structures to house their colonies and nest structures.<ref>{{Cite journal|journal= Biological Conservation| volume= 115 |issue= 2| year=2004| pages= 279–289| title= Impact of human dwellings on the distribution of the exotic Argentine ant: a case study in the Doñana National Park, Spain | vauthors = Carpintero S, Reyes-López J, de Reynac LA |doi=10.1016/S0006-3207(03)00147-2| bibcode= 2004BCons.115..279C }}</ref><ref>{{cite journal | vauthors = Friedrich R, Philpott SM | title = Nest-site limitation and nesting resources of ants (Hymenoptera: Formicidae) in urban green spaces | journal = Environmental Entomology | volume = 38 | issue = 3 | pages = 600–607 | date = June 2009 | pmid = 19508768 | doi = 10.1603/022.038.0311 | name-list-style = vanc | s2cid = 20555077 | doi-access = free }}</ref>
