Transmission of Trypanosoma cruzi (Chagas disease) by Triatoma infestans remains a major public health problem in the Gran Chaco ecoregion. Promotion and effective implementation of housing improvement (including key peri domestic structures such as chicken roosts) combined with appropriate insecticide use and host management practices are needed to eliminate infestations. Better housing with fewer refuges for bugs will likely reduce the chance of residual foci after insecticide spraying, and facilitate community-based vector surveillance. A more integrated perspective that considers simultaneously social, economic and biological processes at local and regional scales is needed to attain effective, sustainable vector and disease control.
