Why 82% of Europeans are moving past DEET, and what actually works instead

A consumer market does not turn on a single product launch. It turns when a preference reaches a scale where the previous default stops being the default. In 2026, the EU mosquito-protection market is finishing that turn.

According to Coherent Market Insights' 2026 survey, 82% of surveyed EU consumers prefer DEET-free mosquito protection, and 64% prefer biodegradable or non-toxic formulations. The natural insect repellent market is growing at a compound annual rate of 9.55%, according to Future Market Insights' 2026 outlook. These are not fringe numbers. They are the shape of a market where the chemical default is being replaced - quietly, without protest, because consumers have alternatives they trust.

That is the story. The interesting part is what is replacing it.

What we know

• 82% of surveyed EU consumers prefer DEET-free mosquito protection (Coherent Market Insights, 2026).
• 64% prefer biodegradable or non-toxic formulations (Coherent Market Insights, 2026).
• The natural insect repellent market is growing at 9.55% CAGR (Future Market Insights, 2026).
• Citronella candles provide roughly 68% protection for about three hours - a useful outdoor interval, not an all-evening solution (peer-reviewed citronella efficacy literature).
• Indoor plug-in diffusers release actives into the air of a small room overnight; skin-applied repellents need reapplication and skin contact to work.
• The Mainland EU autochthonous dengue + chikungunya counter is holding at zero through Q2 2026 per the European Centre for Disease Prevention and Control's W25 monthly report; the W27 monthly is pending. Consumer interest in non-chemical protection is rising in the same window where institutional cost accounting for any future outbreak is being built (Apouey et al., IJID Regions, PMID 42382010).

The shift, named honestly

DEET is an effective active ingredient. It has been used for decades, it works, and for travel to high-risk areas it remains part of the WHO-aligned protective set. Saying that is not a contradiction with saying that 82% of EU consumers want an alternative. Both can be true at once, and both are.

What has changed is not the chemistry. What has changed is what consumers want from mosquito protection when they are not travelling. At home, in the bedroom, on the terrace, with babies and toddlers in the room, the calculus is different. The skin-contact question, the reapplication question, the inhalation question, the residue question - each of these is a small friction that compounds. Eight out of ten EU consumers are choosing to remove it.

What 82% are choosing instead

The replacement is not a single product category. It is a small family of physical-barrier approaches that share one structural feature: they keep the mosquito away from the person, rather than coating the person with an active that deters the mosquito.

Physical barriers work by exclusion, not by chemistry. A correctly sized untreated mosquito net - over a crib, over a bed, or over an outdoor living structure - keeps the mosquito away from the skin entirely. There is nothing to absorb, nothing to inhale, nothing to reapply. The mechanism is geometry and mesh, not active ingredient.

Two product shapes inside Mosticare's range do this work for the home:

• Untreated bedroom canopies - for night sleep, for babies and toddlers in cribs, for adults who want a no-skin-contact night. No DEET, no permethrin, no diffuser running by the bed, no repellent on the pillow. The barrier is the canopy itself.
• The Terrazza TE-UNO and TE-DUE outdoor gazebos - EU-designed dedicated outdoor structures for terraces, gardens, and outdoor dining. Untreated, zero-chemical, and built for the European outdoor-living scale. No citronella candle to relight every three hours, no CO2 trap system to power, no skin-applied repellent to remember.

Both do the same structural work as the DEET-spray-and-skin pathway - they keep mosquitoes away from people - but they do it without putting anything on the skin or in the air. That is the reason 82% are choosing them.

Where the chemical answer still belongs

It would be wrong to read this shift as "DEET is out." It is not. DEET, and permethrin-treated nets, are part of the WHO-aligned protective set for travel and high-burden settings. WHO prequalification and the EU Biocidal Products Regulation apply to treated nets, not to the untreated canopy line or to the Terrazza range, and that distinction matters when you are choosing between products.

If you are travelling to a region with documented malaria or dengue transmission, the treated-net pathway is the right pathway. The treated net is a different product, in a different message lane, doing different work. It is not competing with the untreated canopy. They sit next to each other.

What is shifting is the home and the terrace. For night sleep and outdoor living inside the EU, the preference - and the structural answer - has moved to physical barriers.

The honest trade-offs

A physical barrier is not a free upgrade. It has trade-offs worth naming:

• Installation. A canopy or gazebo is a structural choice in the room or on the terrace. It is not a spray you can put on in ten seconds.
• Sizing. A baby crib needs a baby-sized canopy; an adult bed needs an adult-sized canopy; a terrace needs a terrace-sized structure. The product shape matters and the wrong size does not do the work.
• Mesh and weave. Barrier protection depends on mesh integrity. A torn or stretched canopy is not a canopy. Periodic inspection is part of the answer.
• Indoor air chemistry. Physical barriers leave indoor air chemistry alone. That is the point. It also means there is no active ingredient working in the room. For night sleep in low-risk areas that is the right answer; for high-risk travel it is not.

These trade-offs are the case for honesty. The shift to physical barriers is real, and the trade-offs are real, and naming both is how consumer trust in the category is built.

What this means for the next twelve months

The 82% number is not going to soften. The structural drivers behind it - autochthonous arbovirus pressure in mainland Europe (Mainland EU holding at zero through Q2 2026 per ECDC, but the French 2025 autochthonous chikungunya wave of 809 cases and 30 dengue cases is now in the cost-accounting literature, per the IJID Regions paper, PMID 42382010), the spread of Aedes albopictus north and west across Europe, and the sustained consumer preference for untreated protection at home - are not temporary.

Three practical consequences for the EU consumer:

1. At home and on the terrace, the physical-barrier answer is no longer niche. It is the structural default for 82% of consumers. The product range available to support it is mature.
2. For travel to high-risk areas, the treated-net answer remains. WHO prequalification is the right standard for that context; an untreated canopy is not.
3. The cost-accounting frame is now in print. The IJID Regions paper sets a quantitative floor on what a single autochthonous season costs in a non-endemic country. That makes the prevention layer - physical barriers included - easier to argue for in household budget terms, not just preference terms.

The chemical default is not collapsing. It is being relocated. The home and the terrace belong to the physical-barrier answer now. Travel and high-risk settings still belong to the chemical answer. Both of those can be true, and both of them are.
