  • When choosing an insect repellent, consider two factors: safety and effectiveness.
  • Look for repellents that are EPA-registered, which ensures they have been tested and proven effective.
  • DEET is a widely used ingredient and is safe for children when applied in the correct concentration.
  • Picaridin is another safe and effective option, with effectiveness also depending on concentration.
  • Oil of lemon eucalyptus can be effective but should not be used on children under age three.
  • For all repellents, effectiveness is tied to proper concentration and correct use.
