The sampling technique was performed using total sampling utilizing a light trap installed in the room from the afternoon until the morning. The total number of mosquitoes captured in the two locations was 101, consisting of 46 non-Aedes sp (45.5%) and, 55 Aedes sp (53.9%).  Captured Aedes sp mosquitoes consisted of 2 species, that is 6 Ae. albopictus (5.9%) and 49 Ae. aegypti (48.5%). Ae. aegypti mosquitoes were more commonly found as a vector for CHIKV infection in Peregae hamlet, Mengwi village, and Buana Desa hamlet, Padangsambian sub-district
