From the newborn cot to the toddler bed, the safest mosquito protection for a child aged 0 to 3 in Italy, France or Germany is the same thing every paediatric and public-health body recommends: an untreated fine-mesh net over the sleep space, with no chemistry on the skin or in the air. Repellents become age-permitted at low concentration from two months, but the child's own bedroom stays the place for the zero-chemical barrier. This guide sets out the age ladder, why the untreated bedroom canopy is the default across the whole 0 to 3 band, and the practical setup for the 2026 season.
For a child aged nought to three in Italy, France or Germany, the safest mosquito protection is the same across the whole age band: an untreated fine-mesh net over the sleep space, with no chemistry on the skin and none in the air. The American Academy of Pediatrics, the US Centers for Disease Control and Prevention, the French ANSES, the German BfR and the Italian Istituto Superiore di Sanita all point the same way for young children [AAP 2024; CDC 2026; ANSES 2023; BfR 2023]. Repellents become age-permitted at low concentration from two months, but the child's own bedroom stays the place for the zero-chemical barrier. This guide sets out the age ladder, why the untreated bedroom canopy is the default from the cot to the toddler bed, and the practical setup for the 2026 season.
If you have two minutes, read the age ladder and the five rules for the bedroom below. For the reasoning and the primary sources, the reference list at the end cites the official documents.
Why the bedroom is the question for summer 2026
Two vectors matter for a European child's room, and they bite at different times of day.
The Asian tiger mosquito (Aedes albopictus) is a daytime biter, most active at dawn and in the late afternoon. It is now established in 369 regions across 16 European countries, up from 114 regions a decade earlier, per ECDC's World Mosquito Day 2025 review. In metropolitan France the 2025 season produced 809 locally acquired chikungunya cases and 30 locally acquired dengue cases, per the Sante publique France report published 6 May 2026. The same vector had colonised 81 of the 96 metropolitan departments by 1 January 2025. The Italian bulletins from EpiCentro ISS track the same picture south of the Alps.
West Nile virus is the second vector story, and it changes the timing. West Nile virus is spread by Culex mosquitoes, which bite mainly from dusk to dawn, and it is a recurring summer risk in parts of southern and central Europe, Italy included, per ECDC. A daytime net alone does not answer a night-biting mosquito. A net over the child's bed, used for every sleep, answers both.
The European Commission's DG Environment said on 14 January 2026 that Paris, Vienna, Zagreb and other European cities face a higher dengue, Zika and chikungunya risk than ten years ago. For a parent, the practical reading is simple. Mosquitoes reach the child's room, by day and by night, across most of the warm half of the year. The bedroom is where a small child spends the most hours, so the bedroom is where the barrier earns its keep.
The age ladder from nought to three
The public-health guidance is staged, and the stages matter because they change what a parent may and may not put on the skin.
Nought to two months. No skin-applied repellent of any kind. The barrier is the whole of it: an untreated fine-mesh net over the cot, the carrycot and the pram, plus long-sleeved clothing [AAP 2024; CDC 2026].
Two months to three years. Low-concentration repellents become age-permitted for exposed skin when the child is out and about: the CDC allows 10% DEET or 10% picaridin (also called icaridin) from two months, and IR3535 is used from a low concentration [CDC 2026; BfR 2023]. Oil of lemon eucalyptus, also called PMD, carries a stricter floor and should not be used before three years [AAP 2024; CDC 2026]. ANSES makes the same point for France: mechanical protection first for the youngest children, with repellents reserved and dosed by age [ANSES 2023].
Here is the part parents ask about most. A repellent becoming age-permitted does not make it the right choice for the bedroom. Repellents are for exposed skin during active daytime hours outdoors. For sleep, and for a child's own room, the untreated net is the zero-chemical default at every stage of the nought-to-three band. The skin stays clear of chemistry overnight, and the barrier does the work.
Why the untreated bedroom canopy is the default
The untreated net is a pure physical barrier. It carries no active substance and makes no biocidal claim. A fine-mesh, intact, correctly fitted untreated net keeps the mosquito out by mesh and fit alone, which is why every public-health body treats it as the safe default for a young child.
For this age band, three things make the bedroom canopy the default rather than a nice-to-have.
- The child sleeps long hours in one room. Exposure concentrates where the hours are. A canopy over the cot or the bed covers the daytime nap, the dawn window and the night, so it answers both the daytime tiger mosquito and the night-biting Culex.
- The sleep space changes across nought to three, and the net follows it. The newborn is in a cot, so the default is an untreated cot canopy tucked under the mattress. The toddler moves to a toddler bed or a low floor bed, so the default becomes an untreated bed canopy that reaches the floor and closes fully. The principle holds; the fit is what you adjust.
- A young child pulls, climbs and kicks. A loose net or a gap at the tuck is an open door. For a toddler, the fit is the whole safety margin, so the net must close and re-close every time, and it must have no gap a small hand can open.
On treated nets, the line is worth stating plainly because the 2026 numbers tempt parents towards a "stronger" option. A treated net carries an insecticidal active substance, almost always permethrin in Europe, and it is authorised under the EU Biocidal Products Regulation and built to WHO standards for malaria-endemic settings. That is a real public-health tool for households at high daily biting risk, often where the alternative is no net at all. It is a different regulatory class, a different setting and a different risk-benefit frame. For a healthy baby or toddler in a non-endemic European home, the precautionary choice for the child's own sleep space is the untreated net, and a permethrin-treated net is not placed directly over the infant. The barrier does not need a chemistry to work.
Five rules for the bedroom
- No skin-applied repellent under two months, and none for sleep at any age under three. The barrier is the measure for the bedroom, day nap and night alike.
- The default is an untreated fine-mesh canopy over the sleep space. Cot canopy for the baby, bed canopy that reaches the floor for the toddler, tucked or closed on every side.
- Fit beats brand. A mesh too coarse lets the tiger mosquito through, and a loose edge lets it in at the tuck. Fine mesh, intact, closed every single time.
- Cover the pram and the day sleep too. An untreated pram net with an edge that grips the chassis handles the daytime tiger mosquito outdoors. Do not drape a cloth for shade and call it protection; the cloth traps heat and the mosquito walks in.
- Cut the breeding sites weekly. Empty the plant saucers, the pet bowls, the buckets and the gutters. The ECDC tiger mosquito factsheet notes that a single flowerpot saucer with a centimetre of standing water is enough for a laying site. The net is half the picture; the breeding-site cut is the other half.
The repellent age floors, in one table

A 2026 bedroom setup that works
The list is short, and it is the one most European paediatric nurses give when pressed.
- Cot, for the baby. Untreated fine-mesh cot canopy, tucked under the mattress on all sides. Re-tuck after every feed, nappy change and cuddle. The opening must close, and re-close, every time.
- Toddler bed or floor bed, for the older child. Untreated fine-mesh bed canopy that reaches the floor and closes fully, with no gap at child height. Check it after the child settles.
- Pram and carrycot. Untreated fine-mesh pram net with an elasticated edge that grips the chassis, for the daytime tiger mosquito outdoors.
- Day and night both. The tiger mosquito bites by day; Culex bites at night. The canopy over the sleep space covers both windows, so use it for the nap as well as the night.
- Window and door screens. Untreated mesh screens on the bedroom window, fitted without gaps, are the second line. They complement the canopy; they do not replace it.
- Breeding sites, weekly. Saucers, buckets, gutters, pet bowls, the paddling pool and any tarp that holds a puddle. The breeding-site cut is half the protection.
Keeping the room cool without dropping the barrier
Summer nights raise a real tension: parents open the window for airflow, and the open window is the mosquito's way in. The NHS safer-sleep guidance sets out room temperature and bedding for the first year, and a hot room is its own risk. The canopy resolves the tension rather than adding to it. A fine-mesh untreated net lets air move through while it keeps the mosquito out, so the window can stay open for the airflow with the barrier still in place. A fitted window screen does the same job at the window itself. Neither traps heat the way a draped cloth does.
Frequently asked
My child is now past two months, so can I use a spray instead of the net at night?
No. A repellent becoming age-permitted is about exposed skin during active daytime hours outdoors. For sleep, and for the child's own room, the untreated net is the default at every stage under three. Keep the skin clear of chemistry overnight and let the barrier work.
Is a plug-in vaporiser or a citronella candle enough for the bedroom?
No. A plug-in vaporiser releases a volatile active into the air, and the cumulative exposure for a young child is poorly characterised; the public-health bodies do not list it as a substitute for the net. Citronella candles have a marginal effect at close laboratory distances and no meaningful effect in a real room. The net is the measure.
We are in Italy or southern France. Does West Nile virus change the advice?
It reinforces it. West Nile virus is spread by Culex mosquitoes that bite from dusk to dawn, so a net used only for daytime naps misses the window that matters most for that virus. A canopy used for every sleep, night included, is the barrier that answers both the daytime tiger mosquito and the night-biting Culex [ECDC].
What about a permethrin-treated net, since the case numbers are high this year?
A treated net is a public-health tool for malaria-endemic regions and a different regulatory class, authorised under the EU Biocidal Products Regulation and built to WHO standards for that use. For a healthy baby or toddler in a non-endemic European home, the precautionary choice for the child's own sleep space is the untreated net, and a treated net is not placed directly over the infant. Travel to a malaria-endemic country is a separate question with separate guidance, and the TravelHealthPro and national travel advice apply.
Does a net prevent disease?
A net reduces bites and the mosquito's entry to the room. It does not prevent or cure any disease, and it is not a substitute for medical advice. It is the physical barrier that lowers exposure, which is what the public-health bodies recommend for a young child.
The single page to keep
For a child aged nought to three, the answer is stable across the whole band: the untreated fine-mesh canopy over the sleep space, the right fit re-checked every time, and the weekly breeding-site cut. The repellent age floors matter for daytime skin outdoors once the child is old enough, but the bedroom stays the zero-chemical room. The primary sources below, from the AAP, the CDC, ANSES, the BfR, the ISS and ECDC, set out the why and the how in full.
