Blood-sucking triatomine bugs, commonly called Kissing Bugs, transmit Trypanosoma cruzi from person to person. There are three genera of triatomine bugs: Triatoma, Rhodnius, and Panstrongylus. The species that most effectively transmits T. cruzi is Rhodnius prolixus. The species that most commonly transmits T. cruzi in North America is Triatoma protacta.

Triatomine bugs prefer habitats that are dark and enclosed, yet near to a mammalian food-source. For these reasons, mud-walled, thatched-roof houses are favorable nesting sites for these bugs. (http://www.arose.net/triatoma/faq.htm)
