Analysis of the type treatment on an insecticidal gel developed for air freshener, derived from essential oils, cloves and bark to test its effectiveness against mosquito mortality. The goal is to find out whether these plants are suitable for use as an antidote to dengue fever (DHF) to make Indonesia better. The solvent used is gasoline benzene. In the manufacture of air freshener insecticidal gel, there are 4 (four) variations in concentration of clove flower essential oil (Syzygium aromaticum, L.), and Lawang bark (Cinnamomun cullilawang Blume), namely 0.5%, 1.0%, 1.5 % and 2%. There was a significant difference in mosquito mortality at each concentration of clove flower essential oil insecticide gel (Syzygium aromaticum, L.) and there was a significant difference in mosquito mortality at each insecticidal gel concentration of the bark of the bark of Lawang (Cinnamomun cullilawang Blume) essential oil. There was a significant difference in the mean of mosquito mortality in the interaction group of residual effects and the concentration of clove flower essential oil insecticide gel (Syzygium aromaticum, L.) and there was a significant difference in the average mosquito mortality in the interaction group of residue effect and insecticide gel concentration. Different essential oils of the bark of Lawang (Cinnamomun cullilawang Blume).
