If you spend time outdoors with children, you’ll need to keep them safe from mosquitos, biting flies and ticks. For young infants, the best approach is to protect them with clothing or nets that cover their strollers. For older children, you’ll need an insect repellent to get the job done. DEET can be used with infants as young as 2 months, but the American Academy of Pediatrics (AAP) recommends not using products with more than 30% DEET: http://www.healthychildren.org/English/safety-prevention/at-play/Pages/Insect-Repellents.aspx. Lower concentrations of DEET work well, but last for shorter periods of time. A 10% concentration lasts for about two hours. I prefer an ingredient called picaridin because it works almost as well as DEET, but feels nicer on the skin. If you want a natural product, the soy-based repellent in Bite Blocker lasts about 90 minutes.

If you use a product containing DEET or picaridin, a lotion or pump spray is safer than an aerosol. Don’t apply it to your child’s hands and be careful to avoid the eyes, nose and mouth. It’s also a good idea to wash it off when you come inside.

You should not use products containing insect repellent and sunscreen. Instead, apply the sunscreen first, wait until it’s absorbed, and then apply the insect repellent. Keep in mind that sunscreen should be used liberally and reapplied every two hours. Bug sprays are applied sparingly and many should not be reapplied. Always read the instructions that come with the product you’re using.
