Is it safe to use bug spray with DEET on toddlers?
Yes, when the label is followed. Use clothing first, then apply DEET carefully when bite risk is real.
What's actually in it
DEET is an EPA-registered insect repellent. It helps keep mosquitoes and ticks from biting. It does not kill bugs. It makes it harder for them to find skin.
For toddlers, the safer routine is simple: cover skin first, then use repellent only when the bite risk is real.
What the research says
CDC mosquito guidance updated in 2026 recommends EPA-registered repellents, including DEET. CDC says not to apply repellent to a child's hands, eyes, mouth, cuts, or irritated skin. For the face, adults should spray repellent on their own hands first and then apply it.
EPA guidance updated in 2025 says DEET is approved for use on children with no age restriction and no percentage restriction based on EPA registration data. EPA also tells users not to spray DEET directly on the face and not to apply it over cuts, wounds, or irritated skin.
Use long sleeves and pants first. When repellent is needed, apply it for your child, keep it off hands and faces, follow the label, and wash it off after coming indoors.
