This study examined the effectiveness and environmental impact of oregano as a natural mosquito repellent compared to store-bought repellents. The findings show that oregano mosquito repellant had a lower environmental impact due to its non-toxic properties. Additionally, oregano, as the main ingredient for a mosquito repellant, is as effective in repelling mosquitoes compared to store-bought repellents. These results suggest that oregano mosquito repellant could be a promising natural alternative to store-bought mosquito coils or repellents, with potential benefits for both human health and the environment. Further research is needed to explore the long-term effects of oregano oil on mosquito control and its sustainability.
