Is natural oil of lemon eucalyptus a safe bug repellent for kids?
Based on 1 peer-reviewed studybaby
Verdict: Use Caution
For kids over 3 yes. Not for babies under 3 because of airway sensitivity.
What's actually in it
EPA-registered oil of lemon eucalyptus (OLE) is effective against mosquitoes. It contains PMD (para-menthane-3,8-diol), a terpene-derived compound. It's labeled not for kids under 3 because young airways react to terpenes.
What the research says
A 2025 study in J Occup Environ Hyg showed terpenes in diffuser air reach workplace exposure levels quickly. Same terpene class is in OLE.
For kids 3 and up, OLE is a good DEET-free option. For babies under 3, use picaridin 10% or keep kids covered with long sleeves and mosquito netting.
