Insect repellent is not a favorite for anyone, but it is necessary for protection against West Nile virus and Lyme disease. There are various formulas available now to make the experience more bearable. Different chemicals like DEET, picaridin, IR3535, and oil of lemon eucalyptus are approved by the EPA and CDC for use against mosquitoes and ticks. DEET is the most effective but can be oily and smelly, while picaridin is just as effective with fewer downsides. IR3535 is more effective against ticks, and oil of lemon eucalyptus is a natural alternative that may work as well as DEET.
Safety concerns about DEET include reports of neurotoxicity, but research indicates that it is generally safe. Other chemicals like picaridin do not pose the same risks. Using insect repellent is important for preventing diseases like West Nile virus and Lyme disease, outweighing the potential risks associated with the chemicals.
When using insect repellent and sunscreen together, apply sunscreen first and avoid combo products to minimize exposure to repellent chemicals. The concentration of repelling ingredients does not necessarily need to be higher for better protection, as 20-30% concentration is generally effective. The choice between sprays, lotions, or wipes comes down to personal preference.
In testing various insect repellents, effectiveness can vary based on the individual and the environment. Mosquitoes are attracted to certain scents, body heat, and sweat, so what works for one person may not work for another. Overall, using insect repellent is crucial for protecting against mosquito and tick-borne illnesses.
