    The objective of this study was to evaluate the in vitro repellent activity of the essential oils of Syzygium aromaticum ('clove') and Cinnamomum verum ('cinnamon') and a 50/50 v/v combination of both oils on Aedes aegypti. The essential oils were obtained by steam distillation, and the area preference method was used to evaluate repellent activity. The repellent activity of the essential oils and the 50/50 v/v combination was evaluated on the Aedes aegypti Rockefeller strain at various concentrations (0.2%, 0.1%, 0.05%, 0.03%, and 0.01%). N,N-diethyl-3-methylbenzamide (DEET) at 15% was used as a positive control, and acetone was used as a negative control. It was concluded that the essential oils of Syzygium aromaticum, Cinnamomum verum, and their combination do have in vitro repellent activity on Aedes aegypti. The minimum repellent concentration was 0.03%, and the repellency time was five (5) hours at concentrations of 0.05%, 0.1%, and 0.2%. Furthermore, the in vitro repellency level was found to be between class IV and V (using the Talukder and Howes rating) at the 0.05%, 0.1%, and 0.2% concentrations from the 1st to the 5th hour.
