| Sumario: | Understanding Aedes breeding sites is crucial for effective vector control, yet the application of Geographic Information Systems (GIS) and spatial analysis in Kuala Lumpur is limited. This study explores the spatial distribution and characteristics of Aedes aegypti and Aedes albopictus breeding sites in dengue-prone areas of Bandar Tasik Selatan. Entomological data from the Kuala Lumpur Health Department (2022–2023) were analyzed using Average Nearest Neighbor (ANN), Global Moran's I, and Kernel Density Estimation (KDE). Logistic regression and principal component analyses (PCA) were used to assess breeding site characteristics. Of 6,027 water containers inspected, 402 (6.7%) were positive for Aedes larvae. ANN and Moran's I analyses revealed significant clustering in Zone A and Zone B, while KDE identified breeding hotspots. Logistic regression indicated higher risk in plastic (aOR = 69.58), rubber (aOR = 35.11), and cement (aOR = 24.70) containers, while rainwater (aOR = 0.24), tap water (aOR = 0.27), and partial shading (aOR = 0.41) reduced risk. PCA revealed key breeding site variations across residential, public, school, and food areas. These findings support targeted vector control, efficient resource allocation, and tailored interventions to mitigate dengue risks in high-priority areas.
