insect repellent

Insect repellent is a substance applied to the skin or clothing that discourages insects like mosquitoes and ticks from landing or biting. It works by either masking the scent signals insects use to locate hosts or by interfering with their sensory receptors. Common active ingredients include DEET, picaridin, IR3535, and oil of lemon eucalyptus. Repellents are an effective way to reduce the risk of insect-borne diseases and discomfort in outdoor settings, providing protection when spent time in environments with prevalent biting insects. Proper use and reapplication are important for optimal effectiveness.
