A mosquito repellent is a substance that is applied on human skin, clothing or any other surface in order to prevent the mosquitoes from crawling or sitting on that surface.
How the mosquito repellent works
Mosquito repellents doesn’t kill mosquitoes. The repellents work by making the human skin or surfaces on which they are applied to be unattractive to mosquitoes. They prevent bites from mosquitoes by preventing blood feeding in the mosquito’s stimuli. The length of time a person is protected from mosquito bites depend on the strength and type of repellent used. A good kind of mosquito repellent will provide many hours of protection just from a single application. Furthermore, for a repellent to be effective, apply it evenly on all exposed skin and surfaces as mosquitoes can quickly detect areas where the repellent has not been applied.
Kinds of mosquito repellents
There are various kinds of mosquito repellents i.e. plant derived repellent, electronic and synthetic chemical repellent. All the plant and chemical categories of repellent have different levels of active ingredients (substance that repels the mosquitos).example of synthetic repellent is DEET (diethlytoluamide). It is one of the most effective and widely used repellent developed by US army in the 1950s.picaridin another chemical repellent was developed in 1990s is as effective as DEET with an even more pleasant smell when compared to DEET. Plant derived repellent include geraniol that is derived from plant oils like lemongrass, citronella & oil of rose. A graniol based repellent is effective between 2-4 hours. Another example of plant derived repellent is lemon eucalyptus oil.it has been effectively used since 1940s and approved by CDC (center of Disease Control and Prevention).
