This review describes the changes produced by the invasión of the urban environment into the
natural habitat of triatomines, especially
Panstrongylus geniculatus
, known vectors of Chagas’

triatomines, as well as the importance of these changes and their impact on transmission of
Chagas’ disease. Some measures are proposed to limit the presence of triatomines in urban
dwellings
