Aedes aegypti is a kind of mosquitoes which act as a most important domestic vector of urban yellow fever and dengue fever (DF). The spread of these types of diseases is very wide in urban area, covering almost all tropical regions around the world. The aim of this study was to determine the spatial distribution of Aedes aegypti in East Java from 2008 to 2010. Sample check survey was carried out in nine locations in East Java. Its purpose was to collect information on the presence or absence of potential habitats of Aedes aegypti in the region. Incidence rate (IR) of DF, house index (HI), containers index (CI) and breteau index (BI) were calculated. The landing resting of Aedes aegypti and total catches of adult mosquitoes by the aspirator were also undertaken. The results showed that Aedes aegypti was more often found at indoor than outdoor. The highest CI and BI were recorded at 36.11 and 70.59 % respectively in Nganjuk District. The highest Aedes aegypti house index was 51% in Bangkalan District. In these districts, there are many good habitats for Aedes aegypti larvae.
