Mosquitoes are well known for being vectors of many pathogens causing diseases. The widespread use of synthetic insecticides in mosquito control has resulted in the growth of resistance to pesticides and the degradation of the ecosystem. Therefore, plants have become alternative sources of mosquito control in recent years. In the current research five plants viz. eucalyptus, neem, mint, niazbow, ginger and canola were evaluated against Aedes aegypti and A. albopictus mosquitoes. The toxicity of the crude extracts of all the plants against the third stage larvae of Aedes spp. gave significant results. The study showed a very substantial difference in the length of the repellents and the bite safety between the repellents and the control. Canola was less effective as compared to all other test plants. All the essential oils tested offered protection for a minimum period of > 33 minutes and may therefore be included in the standard list of repellents of Aedes species. Neem oil repellent had the best repellence against both Aedes mosquito species with defence times of (246±15.78) and (256±14.87) minutes respectively against A. egypti and A. albopictus as well. The defence time against A. aegypti was (14.34±0.00) and (19.24±0.00) minutes for the canola oil used as power against A. aegypti as well as A. albopictus. Ginger oil offered the least defence 35.76±4.99 and 33.76±4.99 minutes against A. aegypti and A. albopictus respectively. These two oils were better than other oil formulations and were statistically significant from each other. It is concluded that these plants can be used as alternatives for the management of mosquitos
