Abstract
In this study, we evaluate the effect of participatory Ecohealth interventions on domestic reinfestation of the Chagas
disease vector Triatoma dimidiata after village-wide suppression of the vector population using a residual
insecticide. The study was conducted in the rural community of La Brea, Guatemala between 2002 and 2009 where
vector infestation was analyzed within a spatial data framework based on entomological and socio-economic
surveys of homesteads within the village. Participatory interventions focused on community awareness and low-cost
home improvements using local materials to limit areas of refuge and alternative blood meals for the vector within
the home, and potential shelter for the vector outside the home. As a result, domestic infestation was maintained at
≤ 3% and peridomestic infestation at ≤ 2% for 5 years beyond the last insecticide spraying, in sharp contrast to the
rapid reinfestation experienced in earlier insecticide only interventions.
