However, frequent use of these
synthetic insecticides can lead to disruption of natural biological control systems, development of resistance, and undesirable effects on non-target organisms
Alternative methods of controlling mosquitoes by using more
environmentally friendly approaches have been advocated
(Bhatt and Khanal 2009). In recent years, there has been much
interest in using natural plant-derived insecticides which are
biodegradable, available at low costs, and potentially safer for
human health. Studies on natural plant products have indicated that they could possibly provide alternatives to synthetic
chemical larvicides Plant oils such as
basil, cinnamon, citronella, and thymus have shown promise
as larvicides
