The Natural Patch Co. is made using non-woven fabric patches, infused with a combination of Citronella and other essential oils which are perfectly safe for your kids. Unlike topical sprays which contain DEET or Picaridin, The Natural Patch Co. is not only easy to apply, but environment-friendly! The Natural Patch Co. uses the most effective, but safe, essential oil combination designed to confuse mosquitoes and hide your kids from their senses.
