The locality of Altolândia (Tapiraí Municipality, Minas Gerais, Brazil), frequently presents Panstrongylus megistus infestation in the domiciliary environment. In order to improve epidemiological surveillance in this area, a strategy of domiciliary pyrethroid spraying with high flushing-out effect followed by immediate triatomine research, was implemented in all the existing dwellings. The main objectives were the detection and elimination of cryptic foci, thus reducing the opportunities for new infestations.
