Mosquito repellents are substances designed to deter mosquitoes from landing on and biting human or animal skin. These compounds do not typically kill mosquitoes but rather create an invisible barrier that makes the host undesirable or undetectable to the insects. Their primary function is to prevent bites, thereby reducing the nuisance and the risk of mosquito-borne diseases. Common examples of effective mosquito repellents include products containing DEET, Picaridin, or Oil of Lemon Eucalyptus (OLE).
how do mosquito repellents work
The primary mechanism by which mosquito repellents function involves interfering with a mosquito’s ability to detect and locate a host. Mosquitoes are highly adept at sensing the chemical cues emitted by humans and other warm-blooded animals, such as carbon dioxide, lactic acid, and various volatile compounds present in sweat and breath. Repellents essentially disrupt these sensory processes, making it difficult for the mosquitoes to home in on their targets, thereby protecting the treated area from bites.
