For toddlers 2 months and older, the CDC, EPA, and American Academy of Pediatrics all support using EPA-registered repellents containing DEET, picaridin, or IR3535, applied sparingly and per the product label. For babies under 2 months, skip repellent entirely and rely on netting and protective clothing instead. One rule applies at every age: apply repellent to your own hands first, then onto your child’s skin, and wash it off when you come back inside.
Here’s the quick age-based breakdown for mosquito protection:
- Under 2 months: No repellent. Use stroller netting, long sleeves, and window screens.
- ✅ 2 months to 3 years: DEET, picaridin, or IR3535 per label. Use the lowest effective concentration. Avoid oil of lemon eucalyptus (OLE/PMD) entirely.
- ✅ 3 years and older: All EPA-registered options apply, including OLE/PMD. Match concentration to how long you’ll be outside.
- ⚠️ Every age: Never apply to hands, eyes, mouth, or broken skin. Wash treated skin and clothing after coming indoors.

Which active ingredients are safe for toddlers?
The EPA registers four active ingredients that the CDC and AAP recognize as effective for children: DEET, picaridin, IR3535, and oil of lemon eucalyptus (OLE/PMD). Each works by masking the scents that attract mosquitoes rather than killing them, and each carries different age limits and protection windows.
Concentration matters more than most parents realize. A higher percentage doesn’t mean stronger protection — it means longer protection. Lower DEET concentrations provide shorter protection times while higher concentrations extend that duration, but very high concentrations do not increase protection length., and going above 50% adds no extra duration while raising the risk of skin irritation. For picaridin, Lower picaridin concentrations provide shorter protection times while higher concentrations extend that duration, depending on the product. depending on the product. The takeaway: match the concentration to how long you’ll actually be outside, not to how worried you are.
OLE/PMD has a hard age cutoff. Do not use OLE or PMD on children under 3 years old — this is a firm recommendation from the CDC Yellow Book, not a general caution. Some product labels set this limit explicitly; always check before buying.
Natural essential oils (citronella, peppermint, lavender) are not EPA-registered as repellents. They typically offer shorter, less-documented protection and carry a higher risk of skin sensitivity in young children. They’re not a substitute for EPA-registered options when disease risk is present.
| Active Ingredient | Typical Protection Time | Age Guidance |
|---|---|---|
| DEET (10%) | ~2 hours | 2 months and older |
| DEET (30%) | ~5 hours | 2 months and older |
| Picaridin (5%) | ~3–4 hours | 2 months and older |
| Picaridin (20%) | ~8–12 hours (product-dependent) | 2 months and older |
| IR3535 | Varies by product | 2 months and older |
| OLE / PMD | Varies by product | 3 years and older only |
| Natural essential oils | Short / undocumented | Not recommended as primary protection |
Always read the specific product label. Protection times are estimates; sweating, swimming, and wiping skin all shorten coverage.
Age-by-age guide: what to do for your child right now
Under 2 months
No repellent of any kind. A newborn’s skin absorbs chemicals more readily, and no EPA-registered repellent is labeled for this age group. Your best tools are a stroller or baby carrier net, long-sleeved onesies, and keeping windows screened. If you’re in a high-risk area for mosquito-borne illness, talk to your pediatrician before any outdoor exposure.
2 months to 3 years
DEET, picaridin, and IR3535 products are all options here, used sparingly and strictly per the label. “Sparingly” means a light, even layer on exposed skin — not a second coat for good measure. Avoid OLE/PMD products completely in this age band. For short outings in low-risk areas, non-chemical measures (netting, clothing) are often enough and reduce how much repellent your child needs.
Pro Tip: For toddlers in this age group who are crawling or putting their hands in their mouths constantly, prioritize long sleeves and pants over repellent whenever the outing is brief. Save the repellent for longer outdoor time or higher-risk settings.
2–3 years and older toddlers
By age 3, all four EPA-registered ingredient categories are on the table, including OLE/PMD. Active toddlers who spend hours outside benefit from a slightly higher concentration so you’re not reapplying every 90 minutes. Still, keep the amount minimal — using more than the label directs doesn’t extend protection and increases irritation risk in children’s more absorbent skin. Always read the label before every use, even for a product you’ve used before.
How to apply repellent safely to a toddler
Follow these steps every time, in this order:
- Apply repellent to your own hands first. Never spray or pour directly onto your child’s skin.
- Rub onto exposed skin only — arms, legs, and the back of the neck. Skip any skin covered by clothing.
- Avoid hands, eyes, mouth, and any cuts or irritated skin. Toddlers put their fingers in their mouths constantly; repellent on their hands is a direct ingestion risk.
- For the face and neck: apply repellent to your hands, then dab carefully around the hairline and forehead, staying well away from eyes and lips. Alternatively, apply to a cloth and wipe gently.
- Use the minimum amount needed to lightly cover exposed skin. A thin layer is all you need.
- If using a spray: never spray directly onto a toddler. Spray into your hands or onto clothing in an open, ventilated space to avoid inhalation.
- Reapply per the label — not more frequently. If you go swimming or your child sweats heavily, reapply after drying off.
- Wash treated skin and clothing with soap and water when you come back indoors.
The EPA’s core rule for children: Apply repellent to your own hands first, then apply it to the child. Avoid the child’s hands, eyes, mouth, and any cuts or irritated skin. Wash treated skin and clothing after returning indoors.
Pro Tip: Keep a small bottle of unscented baby wash near the door so washing off repellent becomes part of the “we’re home” routine — kids adapt to routines fast, and it removes the friction of remembering later.
Non-chemical ways to protect your toddler from mosquitoes
Chemical repellents are one layer of protection, not the only one. These measures work on their own for low-risk outings and pair well with repellents for higher-risk settings:
- Dress for coverage. Lightweight long-sleeved shirts and long pants in breathable fabrics like cotton or moisture-wicking blends keep mosquitoes off skin without overheating your toddler. Light colors are a bonus — mosquitoes are drawn to dark clothing.
- ️ Use stroller or carrier netting. Mosquitoes bite day and night, so netting over a stroller or baby carrier is one of the most reliable barriers for infants and young toddlers who can’t yet use repellent.
- Keep window and door screens intact. A torn screen is an open invitation. Check yours at the start of mosquito season and patch or replace any damage.
- Run a fan outdoors. Mosquitoes are weak fliers. A box fan or oscillating fan aimed at the play area creates airflow they can’t navigate, cutting down bites significantly during backyard time.
- Remove standing water around your home. Mosquitoes breed in as little as a bottle cap of water. Empty birdbaths, flowerpot saucers, and clogged gutters weekly. This is the single most effective environmental control you have.
- Time outdoor play wisely. Many mosquito species are most active at dawn and dusk. Scheduling outdoor play for mid-morning or mid-afternoon reduces exposure without any product at all.
- Consider permethrin-treated clothing. Permethrin-treated garments provide protection through multiple washes and are safe when used on clothing and gear. One critical rule: never apply permethrin directly to skin. It’s for fabric only.
Natural repellents and essential oils: what parents should know
Natural and plant-based repellents appeal to a lot of parents, and that’s completely understandable. The honest picture is a bit more nuanced than the marketing suggests.
EPA-registered vs. natural options
| Feature | EPA-Registered (DEET, Picaridin, IR3535) | Natural / Essential Oil Products |
|---|---|---|
| Documented effectiveness | Well-established | Variable, often shorter-lasting |
| Age guidance | Clear (2 months+) | Varies widely by product |
| OLE/PMD age limit | 3 years+ | 3 years+ (where applicable) |
| Recommended for disease-risk areas | ✅ Yes | ⚠️ Not as primary protection |
| Skin sensitivity risk | Low when used correctly | Higher with some plant oils |
The CDC and AAP recommend EPA-registered ingredients when mosquito-borne disease risk is present — dengue, Zika, West Nile, and others. Natural essential-oil products (citronella, peppermint, lavender) vary widely in formulation and duration, and their effectiveness is less consistently documented.
- ✅ When natural options make sense: short outdoor exposure in a low disease-risk area, paired with protective clothing and netting.
- ⚠️ When to choose EPA-registered: any area with known or elevated risk of mosquito-borne illness, longer outdoor time, or when you need reliable, documented protection.
- OLE/PMD reminder: even though OLE is plant-derived, it still carries the hard age restriction of 3 years and older.
What to do if your toddler is bitten or reacts to repellent
Mosquito bites are usually minor, but reactions to repellent need prompt attention. Here’s what to do:
For a mosquito bite:
- Wash the bite with soap and water.
- Apply a cool, damp cloth for a few minutes to reduce swelling.
- For itching, a small amount of age-appropriate topical anti-itch cream (like 1% hydrocortisone) can help. Check with your pediatrician before using oral antihistamines in toddlers under 2.
- Watch for signs of infection: increasing redness, warmth, swelling, or pus. Call your pediatrician if these develop.
If you suspect a reaction to repellent:
- Wash the product off immediately with soap and water and stop using that product.
- Monitor your child for 30–60 minutes.
- Contact your pediatrician or call Poison Control (1-800-222-1222) if symptoms persist or worsen.
Emergency signs — call 911 or Poison Control immediately:
- Difficulty breathing or wheezing
- Facial swelling or hives spreading beyond the application site
- Severe vomiting
- Loss of consciousness or unusual drowsiness
- Suspected ingestion of repellent
Poison Control’s number is 1-800-222-1222 (US). Save it in your phone now, before you need it.
How to combine repellent with sunscreen on a toddler
Sunscreen and repellent both matter on a sunny outdoor day, and the order you apply them in affects how well each works.
- ☀️ Sunscreen goes on first. Apply sunscreen, let it absorb for a few minutes, then apply repellent on top.
- Avoid combination sunscreen/repellent products for young children. Sunscreen needs to be reapplied every 2 hours (or after swimming), but repellent should only be reapplied per its own label. A combined product forces you to over-apply repellent every time you reapply sunscreen.
- Use clothing to reduce how much product you need. The less exposed skin, the less repellent and sunscreen required — and the lower the total chemical load on your toddler’s skin.
- Reapply after water exposure. Both products wash off with swimming or heavy sweating. Reapply sunscreen on schedule; reapply repellent only as directed on the label, not automatically after every swim.
- Apply repellent to exposed skin only — never under clothing, and never more than a light, even layer.

The case for being honest with parents about “natural” repellents
There’s a real tension in this space that most articles gloss over. Parents who prefer natural products aren’t being irrational — they’re responding to legitimate concerns about what goes on their child’s skin. But the wellness market has made “natural” synonymous with “safe and effective,” and for mosquito repellents, that equation doesn’t always hold.
Here’s what the evidence actually shows: EPA-registered ingredients like DEET and picaridin have decades of safety data behind them, including for use on young children. Natural essential oils have far less. That doesn’t make natural products dangerous — it makes them less certain, especially when the stakes are higher (think travel to areas with dengue or Zika).
The smarter approach isn’t “chemical vs. natural.” It’s matching the tool to the situation. Short backyard play in a low-risk area? A natural balm paired with long sleeves and a fan is a perfectly reasonable choice. A camping trip in a region with active West Nile cases? That’s when you reach for the EPA-registered option, full stop.
Jeffi’s position is straightforward: when disease risk is real, use what works. When risk is low and you prefer a gentler formula, a clearly labeled DEET-free product used alongside non-chemical measures is a sensible middle ground. Parents deserve that honest framing, not a sales pitch dressed up as safety advice.
