This quasi-experimental research aimed to develop a working model of Aedes larva control. It compared the household index (HI) between the previous control models of using Abate and the new control models of using Red lime. The implementation site was Huay Hin subdistrict, Nonghong District, Burirum Province. Samples were all of 112 households in that site, using household survey forms for data collection during May - October of 2011 and 2012. Descriptive statistics were used for data analysis. The results showed that after implementing the new model, the HI decreased from 14.29% to 2.08% and the Container Index - CI decreased from 5% to 0.21%. Infection rate of Dengue Hemorrhagic Fever was decreased from 180.83 per 100,000 populations to be none. There was no effect to PH of water. In conclusion, the new control models of using red lime can decrease HI leading to decrease the infection rate of DHF. This is a key success factor of DHF control. Expansion of this model to other area is recommended.
