Insect repellents are substances that are applied to the skin, clothing, or other surfaces to prevent insects from landing, biting, or crawling on them. These products work by either masking the human scent or by repelling insects with their odor. Insect repellents are commonly used to protect against mosquitoes, ticks, fleas, and other biting insects that can transmit diseases such as malaria, dengue fever, and Lyme disease. The most common active ingredients in insect repellents are DEET (N,N-diethyl-meta-toluamide), picaridin, IR3535, and oil of lemon eucalyptus. DEET is the most effective and widely used insect repellent, and it is effective against a wide range of insects. Picaridin is a newer alternative to DEET that is less toxic and has a milder odor. IR3535 is a synthetic repellent that is effective against mosquitoes and ticks. Oil of lemon eucalyptus is a natural repellent that is derived from the leaves of the lemon eucalyptus tree. Insect repellents come in various forms, including sprays, lotions, creams, and wipes. They should be applied to all exposed skin, but not to the eyes, mouth, or open wounds. Insect repellents should also be washed off after returning indoors, and they should not be applied under clothing. While insect repellents are generally safe when used as directed, they can cause skin irritation or allergic reactions in some people. Pregnant women and young children should use caution when using insect repellents, and they should consult with a healthcare provider before using them.
