The New World triatomine species occur from just south of the Great Lakes region of the USA to southern Argentina, with all but a few species concentrated in subtropical and tropical regions.
Kissing bugs can be divided into three general habitat groups: sylvatic, peridomestic, and domestic. Sylvatic forms inhabit nests, burrows and natural hiding places. Peridomestic forms utilise domestic animals as hosts by living in chicken coops, stables, corrals, as well as rabbit and guinea pig houses. The domestic (domiciliary) species have colonised human habitations, where they depend on human or domestic animal blood as food source.
