Abstract: The Continuous use of synthetic insecticides and its toxicity problem together with the growing incidence of insect resistance has called the need for novel insecticide. Plant extracts may be alternative sources that constitute a rich source of bioactive compounds that are biodegradable and environmental friendly. Therefore, the present research is aimed at assessing the larvicidal activity of Hyptis suaveolens and Balanites aegyptiaca acetone leaf and root extracts against mosquitoes larvae. World Health Organisation protocol was adopted for the larvicidal bioassay.
