Reduviid bug
In Chagas-endemic areas, the main mode of transmission is through an insect vector called a triatomine or reduviid bug.The bugs emerge at night, when the inhabitants are sleeping. Because they tend to feed on people's faces, triatomine bugs are also known as "kissing bugs." After they bite and ingest blood, they defecate on the person. Triatomines pass T. cruzi parasites (called trypomastigotes) in feces left near the site of the bite wound.
