Dengue Hemorrhagic Fever (DHF) remains a public health problem in Indonesia that requires environmentally based prevention efforts and active community participation. The reliance on chemical insecticides for mosquito control may cause negative impacts on human health and the environment. The utilization of local plants such as lemongrass (Cymbopogon citratus) and lime (Citrus aurantifolia) as natural repellents offers a safer and household-based alternative. This community service program aimed to improve the knowledge and skills of housewives in utilizing lemongrass and lime through demonstrations of making natural mosquito repellent spray. The activity was conducted for two days at the Muhajirin Village Arts Hall using counseling with leaflet media, demonstration sessions, and independent practice. The results showed an increase in participants’ understanding of the relationship between household environmental management and DHF incidence, as well as improved skills in independently producing natural spray. This activity had a positive impact on raising community awareness regarding the potential of local plants and supporting environmentally friendly DHF prevention efforts.
