Bug Spray for Babies and Toddlers: What Age, DEET vs Picaridin, and How to Apply and Store It
The CDC says no repellent before 2 months. Here is what the CDC, AAP and EPA say about DEET, picaridin, applying it and storing it.
The CDC says not to use insect repellent on babies younger than 2 months old. For that age, the CDC’s route is clothing that covers your baby’s arms and legs, plus mosquito netting over strollers and baby carriers.
So when can babies use bug spray? The CDC’s answer starts at 2 months, and after that the details matter: which active ingredient, what strength, where it goes on the body, and where the bottle lives when you’re done.
When Can Babies Use Bug Spray: The Age Lines
The CDC sets the age line for any repellent at 2 months. The AAP adds limits on DEET strength, and both organizations say to avoid OLE and PMD products for children under 3. Here is how the guidance stacks up.
| Age band | What the CDC and AAP say |
|---|---|
| Younger than 2 months | CDC: clothing and netting only |
| 2 months and older | CDC: follow label; AAP: 30% DEET max |
| Until at least 2 years old | AAP: apply DEET sparingly |
| Younger than 3 years | CDC, AAP: avoid OLE, PMD |
The bands overlap. A baby past the 2-month line still falls under the AAP’s DEET limit, the AAP’s note about young skin, and the CDC and AAP warning on OLE and PMD. Clearing one line does not clear the others.
The CDC also says to always follow instructions when applying insect repellent to children. A repellent adds one layer of protection. It does not replace clothing, netting or an adult watching.
Newborns, Older Babies and Toddlers Under 3
Babies younger than 2 months sit entirely on the clothing-and-netting side of the CDC’s line. Picture this: you’re heading to an evening cookout with a baby only a few weeks old in a carrier. The CDC’s plan is a layer of covering clothing and netting over the carrier, not a spritz of repellent.
HealthyChildren.org (AAP) says parents of newborns and premature infants should be especially cautious when deciding whether to apply DEET or other chemicals to a child’s skin. After 2 months, the CDC’s age line is behind you, but the AAP’s caution about young skin still applies. Your pediatrician is the right person to ask whether a repellent suits your baby and which one.
That question is worth bringing to a regular visit, before the first outing of the season. Ask which active ingredient fits your child, what strength to look for, and how it fits with sunscreen. The AAP says combination sunscreen and repellent products are not the answer, so expect the two to be separate bottles.
For a 1-year-old or any child under 3, two limits matter when you read a label. The AAP caps DEET at 30% for children. The CDC and AAP both say to skip OLE and PMD products until age 3, and HealthyChildren.org adds that any OLE product you choose for an older child should be EPA-registered.
For bug spray for babies under 6 months or bug spray for a 1-year-old, the same checks apply. Start with the CDC’s 2-month line, then check the strength, then check the ingredient list for OLE and PMD.
DEET: Strength, Duration and Young Skin
The AAP says that when used on children, insect repellents should contain no more than 30% DEET. HealthyChildren.org (AAP) explains what the percentage means in practice:
- 10% DEET provides protection for about 2 hours.
- 30% DEET protects for about 5 hours.
- A higher concentration works for a longer time, but anything over 50% DEET does not provide longer protection.
HealthyChildren.org (AAP) also says using more repellent than needed does not make it more effective. Use just enough to cover your child’s clothing and exposed skin.
The AAP also says to apply DEET only once a day. Use the protection times above to compare products, and stay within the AAP’s 30% limit for children.
Young skin changes the math. HealthyChildren.org says that until infants and children are at least 2 years old, their skin may be different from an older child’s or an adult’s. For that reason, it says to apply DEET sparingly when needed. The same page says DEET products can cause skin rashes, especially at high concentrations, but these reactions are rare.
Picaridin and Other EPA-Registered Ingredients
The CDC says to use EPA-registered insect repellents with one of these active ingredients: DEET, picaridin, IR3535, oil of lemon eucalyptus, para-menthane-diol or 2-undecanone. It adds that you should always follow product label instructions. The AAP notes that picaridin and other repellents are also deemed safe and effective by the US Environmental Protection Agency. Even so, the label decides how you use any product.
HealthyChildren.org (AAP) gives picaridin protection times:
- Products with 5% picaridin can protect against mosquitoes and ticks for 3–4 hours.
- Products with 20% picaridin can provide protection for 8–12 hours.
On picaridin and age, the CDC’s rule that no repellent goes on babies younger than 2 months old covers every repellent, picaridin included. For anything past that, read the product label and ask your pediatrician.
When you compare bottles, find the active ingredient and its percentage on the label. Then check the ingredient against the CDC and AAP warning on OLE and PMD for children younger than 3 years old. A bottle can look gentle and still be on that list.
One more CDC point matters when you shop. The effectiveness of repellents that are not EPA-registered, including some natural repellents, is not known.
How to Apply Repellent to a Child
The AAP’s guidance, with the CDC and EPA where they agree, comes down to these steps:
Applying Repellent to a Child
-
Read the product label and follow it
The EPA and the CDC both say to read the product label and follow it. -
Sunscreen first, repellent second
The CDC and the AAP say apply sunscreen first, then repellent. The AAP says to avoid products that combine the two. -
Spray in an open area
The AAP says spray in an open area to avoid breathing it in. An adult should help apply it on young children. -
Outside of clothing and exposed skin only
The AAP, CDC and EPA say not to put repellent on skin under clothing. -
Never spray directly onto the face
The AAP, CDC and EPA say spray a little on your own hands first, then apply it to the child’s face. -
Keep it off hands, eyes and mouth
The CDC and AAP say keep it off hands, eyes, mouth, cuts and irritated skin. The AAP says use it sparingly around the ears. -
Use just enough
HealthyChildren.org (AAP) says more repellent does not work better. The AAP says to apply DEET only once a day. -
Wash when you’re back indoors
The EPA says to wash your child’s treated skin and clothes with soap and water, or bathe.
Picture this: you’re at the park, the baby is fussing, and you’re tempted to swipe repellent across a cheek and a hand. Steps 5 and 6 are the ones that matter most in that moment. Spray your own palm, then touch it to the face, and leave the hands alone.
Watch for three mistakes. Spraying in an enclosed space instead of an open area goes against the AAP’s advice to avoid breathing the spray in. Applying repellent under a sleeve or waistband breaks the AAP, CDC and EPA rule about clothing. And layering repellent first, then sunscreen, reverses the order the CDC and AAP give.
Because the AAP says an adult should help apply repellent on young children, treat this as a job you do, not a bottle you hand over. A toddler holding a spray bottle can mist their own face, hands and mouth.
Clothing, Colors and Candles
The CDC leans on clothing for babies under 2 months. HealthyChildren.org (AAP) says to avoid dressing your child in bright colors or flowery prints, because they seem to attract insects.
So the outfit is part of the plan. Covering arms and legs, as the CDC describes, leaves less exposed skin to treat. Plain, less colorful clothing fits the AAP’s advice about bright colors and flowery prints.
The AAP also advises avoiding repellent candles, which may trigger breathing problems when fumes are inhaled. Netting over the stroller or carrier works without anything going on your child’s skin.
Bugs are one of several summer outdoor hazards, alongside sun and water. Plan the whole outing, not just the repellent.
Storing Repellent Out of a Toddler’s Reach
The AAP says to keep all products out of young children’s reach. HealthyChildren.org says to keep repellents out of reach to reduce the risk of unintentional swallowing. The EPA says to store insect repellents safely out of the reach of children, in a locked utility cabinet or garden shed.
Picture this: you finish spraying, set the bottle on the patio table and answer the door. A toddler is the next person to reach that table. The habit that works is putting the bottle straight back where it lives every time.
That habit matters most at the end of an outing, when everyone is tired and the diaper bag is half unpacked. Pick one storage spot and make it the only place the bottle goes. A spray bottle left in a stroller basket, a beach bag or a car cup holder is within a toddler’s reach.
If your storage spot is a cabinet, a lock helps keep it shut. Baby Proof Me’s Magnetic Safety Lock Kit comes in 6-, 12-, 24- and 36-lock sizes with keys. You can fix it with 3M adhesive or screw it in, and the product page says to allow 24 hours for the adhesive to fully bond. The page also says the kit is not a substitute for adult supervision.
An adult opens a locked cabinet with the key. Baby Proof Me’s replacement-key page describes the keys as magnet keys, so keep them out of your child’s reach. A swallowed magnet means immediate medical attention (CPSC): call 911 or Poison Help 1-800-222-1222.
Repellent is one of many products that belong in this routine. Poison prevention at home works room by room, and the garage and garden shed count as rooms.
When to Call for Help
If your child has a reaction to an insect repellent, such as a rash, the AAP lists Poison Help at 1-800-222-1222 or your child’s doctor as the contacts. The AAP also says to call 911 if there is a serious reaction such as trouble breathing or a seizure. Poison Help calls are answered by U.S. poison centers, which America’s Poison Centers represents. For questions about which repellent suits your baby, call your pediatrician. You can also read the AAP’s guidance on HealthyChildren.org.
Save the Poison Help number in your phone before the season starts: 1-800-222-1222 (America’s Poison Centers, 24/7, free, US national hotline). Put it where a second caregiver or babysitter can find it too.
If your child swallows a repellent or any other product, call Poison Help 1-800-222-1222, or 911 if the child is not breathing, is having a seizure or is unresponsive.
Putting It Together
Before 2 months, the CDC’s route is covering clothing and netting. After that, the CDC says to choose an EPA-registered product and follow its label, and the AAP says to keep DEET at no more than 30% for children and use just enough on the outside of clothing and exposed skin. Repellent is one layer of protection, alongside clothing, netting and supervision, and storing it safely belongs with the other home safety basics for babies.
Then store the bottle high or locked, and keep any magnet keys out of reach. If you fix a lock to that cabinet with adhesive, give it the full 24 hours the product page says it needs to bond before you rely on it.
