Dengue hemorrhagic fever (DHF) is a public health problem in Banda Aceh. Banda Aceh is a DHF endemic city by increasing incidence rate (IR) and case fatality rate every year. The highest DHF incidence was in Baiturrahman District (IR = 120 per 100,000 people) and Jaya Baru District (IR = 84 per 100,000 people). Aedes sp larvae existence among people is one of Aedes aegypti population indicators in such region. This study aimed to find out numbers of Aedes sp trapped in each ovitrap (coconut shell, plastic cup, and piece of bamboo) and Aedes sp density level before and after ovitrap installation. This study was explanatory study using quasi-experimental design. The sampling technique was proportional sampling. Population of study was 30 houses. Ovitraps were randomly located in 30 places of 10 subdistricts. Data of trapped Aedes sp larvae numbers was collected four times repeatedly within one week time-lapse. Analysis was conducted using the mean number of larvae in ovitraps and ovitrap index. The number of Aedes sp larvae trapped was 1,265. The most effective ovitrap is piece of bamboo, mean = 123, p value = 0.006, HI = 10.01% (16.66 26.67%), CI = 36.8% (336.06 - 39.74%), BI = 29.97% (73.33 - 103.3%). Health authorities should promote bamboo ovitrap, especially to public as an effort to control Aedes sp.
