The method of collecting Aedes sp. larvae was carried out in 100 residents' houses in neighborhoods 3 and 4 of Damai Village, North Binjai District, Binjai City, North Sumatra Province by observing each water reservoir that has the potential to become a breeding ground for Aedes sp. Aedes sp. larvae colonized until the F1 generation, then tested for resistance to permethrin insecticide using the CDC Bottle method. Data analysis was carried out descriptively. The percentage of death of test mosquitoes was 25% (<80%). It was concluded that the Aedes sp. in Neighborhoods 3 and 4 of Damai Village, North Binjai District, Binjai City were resistant to the insecticide permethrin.
