Culex is known as the vector transmitter of filariasis and encephalitis, and to control its spread, repellent is commonly used. DEET has been widely used and proven as an effective repellent; however, it also has many side effects that may be harmful to the human health. Accordingly,  people tend to prefer using repellents made of natural herbs, such as lemon grass or citronella oil, which have been proven effective. This research was aimed to compare the effectiveness of lemon grass stem extract, at various concentrations, against citronella oil. This was a real comparative, prospective experimental study using complete randomized design. Seven hundred and fifty Culex sp. mosquitoes were divided into 5 treatment groups; 3 groups were treated with lemon grass stem extract at 50% (EBS50), 75% (EBS75), and 100% (EBS100) concentration; the negative control group was treated with aquadest and the positive control group was treated with citronella oil. An observation was conducted to find out the number of mosquitoes that moved to the opposite side of the glass box. The data were analyzed using one-way ANOVA, followed by Tukey HSD test with α = 0.01. The result showed that citronella oil had the highest effectivity, followed by EBS100, EBS75 and EBS50  (p = 0.000-0.005). The conclusion is that lemon grass stem extract is a Culex mosquito repellent which is less effective  than citronella oil.
