Is it safe to use bug spray with DEET on toddlers?
Yes at low concentrations (10-30%) as pediatric groups recommend. Picaridin is an alternative with less skin effect.
What's actually in it
DEET (N,N-diethyl-meta-toluamide) is the most studied insect repellent. Pediatric guidance allows 10-30% on kids over 2 months old. Higher concentrations don't work better, just longer. Alternatives include picaridin, oil of lemon eucalyptus (3+), and IR3535.
What the research says
Studies on DEET in kids have found few adverse effects at recommended concentrations. The larger risk is untreated mosquito-borne illness. A 2025 screening documents chemical loads in related products.
Use 10-30% DEET or picaridin on kids. Apply to exposed skin, avoid hands (kids rub eyes), and wash off when inside.
