The appearance of these products dates back to the Second World War. It begins with the intention of commercializing them to achieve an activation and an increase in agricultural production.
The term "repellent" includes birds, mammals, grasses, insects, microbes and fish that are competitors of humans in terms of food consumption and that, to this end, destroy crops and are disease spreaders.
The sale of repellants has been for many years, and more at the beginning, inadequate and scarce in terms of the information that reaches the consumer about the risk they can cause to health, agriculture or the environment in general.
Female mosquitoes feed on blood to help their eggs develop. When they bite, they let saliva pass to the area where they are biting. Saliva contains proteins that can cause an allergic reaction, such as hives and itching. Some people who are more sensitive may develop blisters or major inflammatory reactions. If the mosquito harbors a virus, it is possible to transmit the virus to humans through saliva.
It should be noted that in the market we can find several types, such as chemical repellants, which have synthetic components and those that are composed of plant derivatives, also known as natural repellants. They exist from the classics in aerosol, foam or lotion, to the most modern that are the electronic ones that emit ultrasound signals and ward off various pests.
This method created during those times of terror was and still is the most effective to avoid mosquito bites are avoiding areas infested by mosquitoes, wearing clothing that protects against bites, and using repellants against mosquitoes.
