Different aromatic plants oils that we obtained are used in different respects. Mosquitoes are the life threatening vectors which cause several harmful diseases like malaria, Zika virus and dengue. This study deals with the essential oils and extracts which work against this life threatening vector. The pesticidal activity of essential oil of Mentha against the mosquitoes larvae is due to its menthol content which is the main aroma spreading component of Mentha . Mosquitoes feed on the blood and severe as the important vector for spreading diseases related to human. Synthetic chemical pesticides are toxic and contaminating our environment.
