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.
