The potential of Cinnamon essential oil as a natural insecticides and ants repellent was studied. Cinnamon cassia bark was extracted using hydrodistillation and soxhlet extraction method with three different solvents i. e. petroleum ether, hexane and dichloromethane. All extraction was carried out for 6 hours at 1 atm. The highest yield of cinnamon oil was obtained by soxhlet extraction in dichloromethane, followed by hexane and petroleum ether were 5.22 %, 3.84 % and 3.71 %, respectively. While only 1.82 % yields of cinnamon essential oil extracted when using hydrodistillation method. The volatile compounds of cinnamon essential oil were identified using GC-MS analysis. The results indicated that 9 major volatile compound were presence such as alcohols, aldehydes, alkenes, carboxylic acids, ether, ester and ketone in the cinnamon essential oil extracted by hydrodistillation. Trans-cinnamaldehyde was found to be the major volatile compound with the highest percentage of 86.67 % by soxhlet extraction using hexane. The repellency and insecticidal activity of cinnamon oil by hydrodistillation method obtained was directly exposed to specimen i.e., ants. The repellency and insecticidal activity of cinnamon essential oil was compared through different concentration of fabricated repellency paper. As a conclusion, solvent extraction shows an effective method on cinnamon essential oil extraction with positive insecticidal and repellent activity on ants.
