Sample size was calculated by the formula of estimation of proportion (n = Z 2pq/ͺ2 ) at 95% significance level. Stratified multistage cluster sampling was used. A total of 500 households of Udupi Taluk were selected randomly for the study. Statistical Analysis Used: Data was analyzed using the SPSS version 15, Chicago, IL.

Results: Results showed that foremost risk factor for vector breading was abundance of coconut shells around houses (73%), containers without covers 50.8% (outdoor) and 20% (indoor). The P < 0.05 was significant for usage of mosquito coil or repellents, having a protective screen for windows, doors in living rooms and use of insecticide spray to reduce mosquito density in urban and rural areas.
