“…Despite the generally sylvatic nature of the triatomine species in the United States (Kagan et al, 1966;Ryckman, 1984;Herwaldt et al, 2000;Beard et al, 2003), and a lack of a suitable habitat in most homes within the country (Zeledón, 1974), studies throughout the Americas and within the United States report numerous cases of sylvatic species biting humans when an opportunity is present. Triatomines can enter a dwelling through an unscreened open window, which may be exacerbated by an attraction to lights that increases the triatomine's lure to the domestic dwelling (Usinger, 1944;Sjogren and Ryckman, 1966;Wood and Wood, 1967;Lent and Wygodzinsky, 1979;Monroy et al, 2003;VazquezProkopec et al, 2004VazquezProkopec et al, , 2006. Upon entering a home, triatomines often go undetected because they generally feed at night and are nocturnal by nature (Lent and Wygodzinsky, 1979;Schofield, 1979;Navin et al, 1985;Herwaldt et al, 2000).…”
