DEET and picaridin are fine for babies over 2 months

DEET and picaridin are effective and safe mosquito repellents for babies and young children older than two months. The scare around DEET is mostly overblown.

The CDC and American Academy of Pediatrics both approve DEET at concentrations up to 30% for children. Picaridin (usually 10-20%) works just as well and doesn’t smell as strong. Both are tested, both work, and both are far better than getting dengue or West Nile.

What to avoid: Oil of lemon eucalyptus and PMD are not recommended under 3 years old. “Natural” sprays with essential oils like citronella or lavender barely work and wear off fast. Don’t trust wristbands, sonic devices, or anything you clip on — they’re useless.

For infants under 2 months: Don’t use repellent at all. Use mosquito nets over strollers and car seats, dress them in long sleeves and pants, and keep them inside during peak mosquito hours (dawn and dusk).

One caveat: don’t overdo it. A thin layer on exposed skin is enough. Don’t spray under clothing, and wash it off when you come inside. But if you’re heading to a park or camping with a toddler, don’t hesitate.

Your kid’s comfort is worth two minutes of spray.
