Some ant species are considered as pests, primarily those that occur in human habitations, where their presence is often problematic. For example, the presence of ants would be undesirable in sterile places such as hospitals or kitchens. Some species or genera commonly categorized as pests include the [[Argentine ant]], [[Tetramorium immigrans|immigrant pavement ant]], [[yellow crazy ant]], [[banded sugar ant]], [[pharaoh ant]], [[Formica rufa|red wood ant]], [[black carpenter ant]], [[Tapinoma sessile|odorous house ant]], [[red imported fire ant]], and [[Myrmica rubra|European fire ant]]. Some ants will raid stored food, some will seek water sources, others may damage indoor structures, some may damage agricultural crops directly or by aiding sucking pests. Some will sting or bite.<ref name="pests">{{cite web|url=http://www.ipm.ucdavis.edu/PMG/PESTNOTES/pn7411.html|title=Pest Notes: Ants (Publication 7411)|publisher=University of California Agriculture and Natural Resources|year=2007|access-date=5 June 2008}}</ref> The adaptive nature of ant colonies make it nearly impossible to eliminate entire colonies and most pest management practices aim to control local populations and tend to be temporary solutions. Ant populations are managed by a combination of approaches that make use of chemical, biological, and physical methods. Chemical methods include the use of insecticidal bait which is gathered by ants as food and brought back to the nest where the poison is inadvertently spread to other colony members through [[trophallaxis]]. Management is based on the species and techniques may vary according to the location and circumstance.<ref name="pests" />
