mosquito repellent based on essential oils
in vivo assay
In a studies by Richard Beever, Tests were undertaken to determine the effectiveness of three mosquito repellents: 95% DEET, Avon Skin So Soft bath oil, and a “special mixture” of substances thought to have insect repellent qualities. The repellents were compared with each other and against a placebo in eight separate test sessions. During each session, the three repellents and placebo were tested simultaneously. Each session lasted between 90 and 120 minutes. After every session, the repellents were thoroughly washed from the test site and a minimum of 72 hours elapsed between tests. There were four test sites: the author’s right arm, left arm, right leg, and left leg. All test sites were of similar surface area. Both mosquito bites and landings were counted as events. Measures were taken to ensure that events were not counted twice.
