The control of mosquitoes in residential areas calls for in-depth knowledge of the breeding habits of the mosquitoes, especially Aedes aegypti and Aedes albopictus. Therefore, this study aims to assess the environmental condition and infestation level of Aedes vectors at selected residential areas in Puncak Alam, Selangor. The aims of this study are to understand the environmental profile of residential areas towards infestation level of dengue vectors. A pilot study was conducted in Puncak Alam in order to understand the infestation profile of dengue vectors in residential areas by assessing the environmental condition index (ECI) in front and yard area of residential area. In this study, a minimum of a hundred houses in each residential area was observed for the environmental condition of front and yard of the premises. Concurrently, a total of thirty ovitraps were placed randomly at outdoor premises in order to measure the infestation level of the Aedes mosquitoes. A total of 318 households were inspected in both front area (Fᴀ) and yard area (Yᴀ) where in general, the environmental condition in front of houses is better than the yard area. The same pattern was also observed in which the infestation level of Aedes mosquito population in Fᴀ and Yᴀ ranged from 15.40 – 35.25 and 11.88 – 47.91, respectively. In conclusion, environmental conditions play a main role in the distribution of dengue vector.
