Dengue and dengue hemorrhagic fever are mosquito-borne viral diseases that coincide with the distribution of Aedes aegypti (L.), the primary vector in the tropical and semitropical world. With no available vaccine, controlling the dengue vector is essential to avoid epidemics. This study evaluates the efficacy of a new smoke-generating formulation containing pyriproxyfen and permethrin in Puerto Libertad, Misiones, Argentina. A fumigant tablet (FT) was applied inside the houses by the community members and compared with a professional application. A treatment combining the application of fumigant tablets indoors and ultralow volume fumigation outdoors was also assessed. The community perceptions and practices about dengue disease and the acceptance of  this new nonprofessional FT were evaluated through surveys. Results show >90% adult  emergence inhibition and 100% adult mortality with these treatments. More than 80% of the  residents applied the FT and preferred participating in a vector control program by using a  nonprofessional mosquito control tool, instead of attending meetings and workshops promoting  cultural changes.
