Why Do We Need Mosquito Repellent?
Before beginning with the best mosquito repellent plants and herbs, let us discuss why we should want a mosquito repellent. Well, the mosquito is a carrier for several pathogenic diseases like malaria, yellow fever, zika, dengue, chikungunya, and even Rift valley disease.
In each public health care sector, huge posters are available to spread awareness of the danger of diseases caused by mosquitoes such as Anopheles, Aedes, Culex causing malaria, yellow fever, and filaria, respectively.
In open water, mosquitoes lay their eggs, so anything from a puddle to a pond can become a breeding ground. Additionally, polluted water contains bacteria and other contaminants that can make mosquito-borne diseases even more dangerous.
*Do you know only female mosquitoes are the carrier for diseases, not male. Yes, the female mosquitoes feed on human blood for nurturing their eggs as it keeps them warm. Do you wonder about the male one? They feed on plant nectar; in fact, both male and female feed on nectar, but only during the time of egg-laying the female mosquito sucks human blood.
How They Find Humans? Female mosquitoes have a natural olfactory sensing capacity, which detects the smell of sweat, the body heat and carbon dioxide we breathe out.
Not only the above said diseases, but various parasitic organisms also make mosquitoes as their secondary host or vector for spreading deadly infections.
In addition to diseases, mosquitoes, or any other insect bites are not pleasant. The red itchy bites and their buzz are annoying. Therefore, we need a natural mosquito repellent or anti-mosquito agent, which keeps them away from our living place.
