Dengue fever is a health problem in Indonesia, especially in the Gorontalo area. One of the efforts to prevent the incidence of dengue fever is the use of natural insecticides, including red ginger. This study aimed to examine the effectiveness of red ginger (Zingiber officinale rosc) squeeze in eradicating the Aedes aegypti larva. This study was experimental study with true experiment approach, conducted in laboratory of public health department, Gorontalo State University. The samples of mosquito larvae used were 500 larva of Aedes aegypti 4th instar mosquitoes taken from dengue endemic areas in Gorontalo. Squeeze of red ginger was given in five concentrations: 60%, 70%, 80%, 90%, and 100%. Result showed the effect of the red ginger squeeze in eradicating the Aedes aegyepti larva in each given concentration (p-value=100).  The  higher  concentration  of red ginger squeeze used the higher larva mortality rate. The Zingiber officinale rosc are expected to be utilized by the community in preventing the dengue fever.
