It's 8:40pm. The monsoon has just broken over Nagpur, and there's that thin whine somewhere near the cot. Your phone is open on a shopping app with four things in the cart: a patch, a band, a roll-on, a "herbal" cream. Here's the short answer before you tap. Under two months, nothing goes on the skin — a well-tucked net, full-sleeve cotton and a fan are the entire plan. From two months, a properly registered repellent (DEET or icaridin) applied to exposed skin is the evidence-backed option, at the lowest strength that covers the outing. And patches, stickers and wristbands, whatever the box implies, do not protect a baby's body.
At a glance
- 0–2 months: nothing on the skin. Net, clothing, fan, and no standing water left anywhere in the house.
- Patches, stickers and bands scent a few centimetres of air around themselves. Arms and legs stay open.
- Oil of lemon eucalyptus (PMD) carries a not-under-3-years restriction on its own label. That's a hard line.
- "Natural" is a marketing word, not a safety category — undiluted essential oils and camphor near a small child's face carry their own risk.
- In India, true repellents are regulated as insecticides, not cosmetics. That one fact explains most of what's confusing on the shelf.
Why the shelf is so confusing: repellents aren't cosmetics
Almost nobody explains this bit, and it decides everything else. A product that genuinely repels mosquitoes is regulated in India under the Insecticides Act, 1968, through the CIB&RC — the same framework that covers farm and household insecticides. Your baby's moisturiser or bath wash sits somewhere else entirely, under the Cosmetics Rules, 2020. Different law, different licence, and nothing like the same bar of proof.
So a soft pastel patch that promises "safe mosquito protection for babies" and carries no CIB&RC registration number is, in practice, a scented novelty hoping you'll read it as protection. The wording is slippery on purpose. "Keeps mosquitoes away." "Mosquito care." "Protection formula." Turn the pack over. Look for a registration number and a named active at a stated percentage. No number, no named active — then the thing has never been tested to repel anything. It's the same label-reading muscle we ask you to build in our complete guide to reading baby product labels in India. The front of the pack is decoration. The back is the truth.
Awkward admission, since it's relevant here: Janma makes nothing in this category. Our Nagpur facility is GMP-certified and FDA-licensed for cosmetic manufacture. That licence does not cover insecticides, and I don't want it to. Doing a baby repellent properly means efficacy trials against live mosquitoes and an insecticide registration — not a cosmetic batch with citronella stirred in. Plenty of brands take the shortcut. We'd rather send you to someone else's product.
Every option, compared
| Option | Youngest age typically allowed | What it actually does | Our take |
|---|---|---|---|
| Mosquito net over cot or pram | Newborn, day one | Physical barrier. Nothing on the skin at all. | The only thing we'd use for an under-two-month-old. Still the best option at every age after that. |
| Loose full-sleeve cotton, socks, fan | Newborn | Covers the skin mosquitoes can reach; moving air makes flying and landing hard. | Free, and skipped constantly because of the heat. Go looser and lighter in the weave rather than sleeveless. |
| Patches, stickers and wristbands | Often printed "3 months+" | Release scented oil vapour into the few centimetres of air around the patch itself. | The weakest thing on the shelf. A sticker on the pram hood does nothing for an ankle 40cm away. |
| Plant-oil roll-ons and creams (citronella, lemongrass, neem) | Varies wildly; many say "6 months+" | Masks body odours briefly. Volatile oils evaporate fast, so protection is short. | Fine for a short evening walk with an older child whose skin tolerates it. Patch-test first. Reapply often. |
| DEET lotion or spray | Not under 2 months; 10–30% above that | The most-studied repellent there is. Higher percentage means longer duration, not stronger protection. | The sensible choice in a dengue or malaria pocket. Lowest strength that covers your outing. |
| Icaridin (picaridin) | Guidance differs — Health Canada allows 10% from 6 months | Protection comparable to DEET, far less odour, doesn't damage plastics and synthetics. | What we'd choose for a child's skin when a registered repellent is genuinely warranted. Hard to find here. |
| Oil of lemon eucalyptus / PMD | Not under 3 years — on the label | Plant-derived and genuinely active, which is exactly why it carries an age restriction. | Works. The under-3 line is a regulatory limit, not brand caution — don't cross it for a toddler. |
| Liquid vaporiser, mats, coils | No child age on most packs | Releases a pyrethroid (transfluthrin, prallethrin, allethrin) into room air to knock mosquitoes down. | Never in a closed room with a baby. Coils are the worst of the lot: that's smoke in a sleeping child's air. |
What's safe at what age
0 to 2 months
Nothing on the skin. No patch, no band, no roll-on, no "herbal" cream, however gentle the label sounds. A newborn's skin is 20–30% thinner than an adult's, so whatever you put on it crosses more readily — and at this age no repellent has a safety record that justifies the exposure. Net long enough to reach the floor, tucked under the mattress. Light full sleeves. Fan on low. That's the whole protocol, and it holds.
2 months to 3 years
Now a registered repellent becomes reasonable, used sparingly. Paediatric bodies including the American Academy of Pediatrics clear DEET from two months at 10–30%; icaridin sits in a similar place, with regulators differing on the exact age. Indian pack labels vary. Read yours, and if the age printed doesn't match what you've read here, ask your paediatrician. Apply it to your own hands first, then onto the child's exposed arms and legs. Never their hands — those go straight into the mouth. Never near eyes, mouth or broken skin. Plain water washes it off when you come indoors for the night. Oil of lemon eucalyptus and PMD stay off the list entirely until three.
3 years and older
Every registered active is on the table now, PMD included. What changes in practice is the clock: a school-age child is outdoors in the late afternoon, which is peak Aedes hour. Repellent on the exposed skin before they go down, long trousers if there's grass, a wash when they come in.
Why patches and bands don't do what the picture suggests
The reason is dull, and a little deflating. A repellent works by holding a vapour layer just above treated skin. That's why a lotion covers exactly what you rubbed it onto and not a centimetre more. A patch or a band puts out the same kind of vapour from one small point — and outdoors, in any breeze at all, it's gone within centimetres. That is simply how vapour behaves, so a wearable device can only cover the small area of skin immediately around it. A band may do a little for the wrist it sits on. The calf is on its own.
Two things I'd flag as a formulator. A concentrated oil blend pressed against one patch of skin for hours is a textbook route to contact dermatitis — which is exactly why the instruction on the pack is to stick it on clothing or the pram, never on the child. And once a crawler peels one off, it's a choking hazard. If you like the ritual of a patch, put it on the pram canopy and be clear with yourself about what it's doing. You're scenting a pram.
"Natural" is not a safety category
Janma is Ayurvedic at heart. I formulate with plant ingredients; I'm not about to dismiss them. But botanical and safe-for-infants are two different questions, and repellents are where that gap is widest. Camphor and strongly cineole-rich eucalyptus oils near the face of a child under two are a recognised respiratory risk. Undiluted essential oils sensitise thin baby skin. Neem oil smells like protection. It behaves like a moisturiser.
We've been here before in the Janma Journal. The sharpest case is why no formulation can make kajal safe for a baby's eyes — some products fail on category, whatever the quality of the manufacturing behind them. For the same lens on two other everyday buys, we've taken apart what's really inside Indian baby wipes and whether talc-free baby powder is actually safer.
What we'd actually do tonight
If you buy one thing after reading this, buy a good net. The rest takes about fifteen minutes and costs nothing.
- Hang the net over the cot before dusk — long enough to reach the floor, tucked under the mattress on all sides, no gap at the head.
- After the evening bath, loose full-sleeve cotton and socks, on before 6pm, when the biting picks up.
- Walk the house with a bucket: cooler tray, plant saucers, terrace pots, the tray under the fridge. Aedes breeds in clean standing water on roughly a weekly cycle, so a Sunday round breaks the loop.
- Fan on low, pointed across the cot rather than at the face. Mosquitoes fly badly in moving air.
- Out after dark with a child over two months? Registered repellent, exposed arms and legs only. Decant onto your hands first, then apply.
- Plain water at bedtime to wash it off. No soap, no second bath.
- Fine-mesh pram net for daytime naps on the balcony — the day-biting mosquitoes are the dengue carriers, so a night-only plan leaves a gap.
Skip vaporisers, mats and coils in a closed room where a baby sleeps. If you use one at all, run it in an open, ventilated room and switch it off before bedtime — and never a coil indoors with an infant.
When to see a doctor
Bites themselves are usually a nuisance, not a problem. Call your paediatrician if your child develops a fever within two weeks of being bitten, especially alongside body ache, a rash or unusual drowsiness — dengue, malaria and chikungunya are all better ruled out early than late. See a doctor too for a bite that turns hot, spreading, oozing or painful to touch; for swelling around the eye; for any breathing difficulty or widespread hives after a repellent or patch; and for crops of firm itchy bumps that keep returning for weeks. And if your baby is under two months and you're anxious about mosquito-borne illness where you live, ask your paediatrician directly. That conversation beats anything on the shelf.
For the aftermath — dry, itchy patches where a child has worried at old bites — a plain, fragrance-free barrier moisturiser on intact skin helps soothe and comfort it. Keep any moisturiser off broken or scratched skin, and ask your paediatrician what to use there. And whatever the pack suggests, no moisturiser repels anything.
In summary
- Under two months, use a tucked-in net, loose full-sleeve cotton and a fan — no repellent on the skin at all.
- From two months, a registered repellent such as DEET at 10–30% or icaridin is the evidence-backed option, applied to exposed arms and legs only.
- Keep oil of lemon eucalyptus and PMD away from children under three — that age limit is printed on the label for a reason.
- Treat patches, stickers and wristbands as scent, not protection; their vapour reaches only a few centimetres and doesn't cover a body.
- Check the back of the pack for a named active at a stated percentage and a CIB&RC registration number — without those, nothing has been tested to repel.
Frequently asked questions
Are mosquito repellent patches safe for a newborn?
We wouldn't use them on a newborn. Under two months, nothing repellent goes on the skin or clothing — use a net, light full sleeves and a fan instead. Patches also carry two practical risks: a concentrated oil blend held against one spot of skin can irritate it, and a peeled-off patch is a choking hazard for a crawler.
At what age can I use a mosquito roll-on or cream on my baby?
Registered repellents such as DEET are generally cleared from two months of age at 10–30%, with icaridin in a similar range depending on the regulator. Indian pack labels vary, so read yours and check with your paediatrician. Oil of lemon eucalyptus and PMD carry a not-under-three-years restriction on the label itself, which shouldn't be crossed.
Is DEET safe for children in India?
Used as directed, yes — it is the most-studied repellent available. Avoid it under two months, stay in the 10–30% range, and apply only to exposed arms and legs, never hands, face or broken skin. Higher percentages last longer rather than working harder, so pick the lowest strength that covers your outing and wash it off indoors.
Do citronella and neem actually repel mosquitoes?
They have some repellent activity, but it fades fast because the volatile oils evaporate within minutes to a couple of hours. That means frequent reapplication and unreliable cover. Plant oils are also not automatically gentler — undiluted essential oils sensitise thin baby skin, and camphor or strong eucalyptus near the face of an under-two is a recognised respiratory risk.
Can I use a liquid mosquito vaporiser in my baby's room?
Not in a closed room while your baby sleeps. Vaporisers and mats release pyrethroids such as transfluthrin or prallethrin into the air you're both breathing all night. If you use one, run it in a ventilated room and switch it off before bedtime. Coils are worse indoors because they add smoke. A net achieves more with zero exposure.
How do I tell a real repellent from a scented novelty?
Turn the pack over. A genuine repellent in India is regulated as an insecticide under the Insecticides Act, 1968, so it names its active ingredient with a percentage and carries a CIB&RC registration number. If the front says "mosquito protection" but the back has no named active at a stated strength, it has never been tested to repel anything.
