Sumario:In most countries, Chagas disease transmission control remains based on domestic insecticide application. We thus evaluated the efficacy of infra-domicile cyfluthrin spraying for the control of <i>Triatoma dimidiata</i>, the only Chagas disease vector in the Yucatán peninsula, Mexico, and monitored potential re-infestation every 15 days for up to 9 months. We found that there was a re-infestation of houses by adult bugs starting 4 months after insecticide application, possibly from sylvatic/peridomicile areas. This points out the need to take into account the potential dispersal of sylvatic/peridomestic adult bugs into the domiciles as well as continuity action for an effective vector control.
