This study was performed in an urban neighborhood of the
capital city of the province of San Juan, Argentina. Erected
as a housing complex, the place consists of 768 flats
distributed in buildings of three and seven floors each. A
survey was carried out in 33% of the dwellings, enquiring
about the number of Triatoma infestans found indoors,
stage of the bug development - nymph or adult - and how these
insects had entered their homes. Adult T.infestans were
found on all floors; 163 people (64%) had found them at least
once, and 130 (51%) several times.
Dispersal flight seems to have been the main mechanism of
infestation by adult bugs in this area, and a total of 51% of
the surveyed inhabitants reported that the insects had flown
into their flats.
