It is quite common in West Africa, South America, some parts of the United States, Indonesia, Malaysia, India, Thailand, Australia, and Philippines. However, the diseases they carry differ based on the geographical location. For example, mosquitoes in West Africa, South America, India are vectors of malaria, also in South America some are vectors of Zika viru, Dengue fever and so on.

Mosquitoes are vectors of many disease such as malaria fever, dengue fever, filariasis, zika virus fever and so on. In view of this, it is important to protect oneself from mosquitoes, especially in areas where they are known to carry disease causing parasites and pathogens. Traditionally, several plants have been used in folk medicine to prevent mosquito bites.

 

Plants are natural ways to keep bugs and diseases off, without the risks of exposure to chemicals in commercially available repellents. Plants can be used in different forms to prevent mosquito bites: planting or hanging plants around the house, applying oils or fresh extracts from plants on the body, or burning plants to ‘smoke’ out the mosquitoes.
