Background: Various methods have been conducted either chemically or naturally to reduce mosquito population, with the aim of preventing transmission of diseases caused by mosquitoes. However, it should be endeavored in mosquito control activities not to cause harm to humans and the environment by utilizing mosquito repellent plants, such as lemongrass. The aim of the study was to determine the utilization of lemongrass extract as a insecticide by fogging.

Materials and Methods: It was an experimental research, the number of samples for each experiment used 20 mosquitoes for treatment and control with 5 repetitions. The study was conducted in August 2015. Data analysis used a one-way ANOVA test.

Results: The average number of dead mosquitoes was 18 (90%). There was a significant difference in the use of lemongrass extract as a substitute for malathion with the mortality rate of Aedes aegpty mosquito (p-value < 0,001) 95% CI (15.69-18.31).

Conclussion: Lemongrass leaves and stems can be used as a substitute for malathion in carrying out fogging activities. We recommend that extracts be made in the form of oil rather than liquid because they are easily soluble in diesel fuel.
