Abstract: Mosquito-borne diseases are the major causes of mortality particularly in tropics. Due to drug and insecticide resistance, personal protection by use of skin repellents has become a common approach of control. The purpose of the study is to determine if synergy exists between Ocimum basilicum, Azadirachta indica and Eucalyptus citriodora oils. Kinga Mosquito repelling Wax® and Vaseline Pure Petroleum Jelly® were included as positive and negative test control respectively. The results showed that Chrysanthemum cinerariefolium extract had no paralytic effect at 0.002% and 0.005% with mean repellency of 81.58 and 85.94 respectively. Similar observation was shown by 10% Azadirachta indica oil and Kinga with a mean repellency 85.79 and 80.53 respectively. Azadirachta indica oil was then reinforced by addition of Sweet basil oil and Lemon eucalyptus oil. A combination that provides complete protection and displayed mosquito paralysis was obtained. The developed formulation can replace Kinga® and alternative to Chrysanthemum cinerariefolium extract.
