Who is the mosquito ?

The mosquito, with its tiny size and annoying buzz, is an insect that may seem insignificant at first glance. However, despite its small size, it has a huge impact on human health and the ecosystem.

Mosquitoes are blood-sucking insects. Females need blood to develop their eggs, while males mainly feed on flower nectar. These prolific little creatures are found in almost all parts of the world except for extremely cold places.

Besides the itchy and irritated skin caused by their bites, mosquitoes can carry dangerous diseases. They are responsible for transmitting serious diseases such as malaria, dengue fever, chikungunya, Zika virus and yellow fever. Each year, millions of people are infected with these diseases, causing considerable human suffering and social and economic disruption in the affected regions.

The consequences of mosquito-borne diseases are not just limited to humans. Wild and domestic animals can also be infected, disrupting local ecosystems and impacting biodiversity.


How to fight against mosquitoes ?

Mosquito control is a constant challenge for health authorities and communities. Preventive measures such as using mosquito nets, removing standing water (buckets, clogged gutters, flower pots, used tires, basins, etc.) where mosquitoes lay their eggs, and using repellents can help reduce the risk of bites and disease.

Research is also being carried out to develop innovative and sustainable mosquito control methods, including the use of genetically modified mosquitoes to reduce their populations, or the implementation of biological control techniques by introducing natural mosquito predators in certain areas.

At Penn'Ty Bio, we offer many ecological solutions to fight against mosquitoes. Vegetable insecticide, repellent, mosquito net, diffusers, essential oils, anti-bite and anti-itch lotion or roll on... By adopting preventive measures, you will help reduce mosquito bites and minimize their impact on your daily life.


Why natural insecticides ?

Getting rid of mosquitoes is one thing (although very difficult, let's face it!), but if you could also preserve your health and your environment, wouldn't that be even better ? Did you know that some conventional insecticide particles remain in your treated rooms for several months ? Smoke is the worst because the particles fall on all objects, textiles, surfaces in the room. Unless you thoroughly wash each item, you will inevitably end up with chemicals. Opting for natural insecticides will allow both to get rid of mosquitoes but also, due to the composition of our products and their low persistence, to continue to live in a healthy environment.

A simple diffuser that works without supervision

Diffuseur à froid anti-moustiques et anti-mouches

The Otentik diffuser uses a very simple process that has proven itself for many years: diffusion by capillary action.

The natural rattan stems are impregnated with the product contained in the bottle and diffuse the active ingredient by capillary rise in a light and constant manner. The rattan stems will absorb the liquid like a sponge. The liquid rises in the stems through their grooves and then evaporates on contact with the air. It is therefore a passive cold diffusion.

Both elegant and discreet, this diffuser, consisting of a vase containing the repellent product, a stopper and a bundle of 8 natural rattan stems, is ideal for effectively fighting flies and mosquitoes. An office, a bedroom, a living room, an entrance, a toilet, a bathroom... Move it wherever you want in your home. No constraints as it is completely autonomous and does not require any electrical connection. The smell is light and discreet but strong enough to keep flies and mosquitoes at bay. 

The stopper allows you to prolong the use of the diffuser. If you don't want to diffuse for a while, you can simply remove the rattan stems and close the vase with the stopper to keep the repellent liquid intact.

A plant-based active ingredient known for keeping insects at bay : geraniol

This diffuser contains 60 ml of a mixture of citronella and geraniol. Also known as Rhodinol, Geraniol is naturally present as a molecule in plants of the Geraniaceae family. (Geranium, Pelargonium, Erodium, ...). It is considered to be 5 times more powerful than citronella. It is obtained by fractional distillation from Cympobogon Winterianus Jowitt by extracting all impurities without any chemical means. This alcohol concentrates the insect repellent properties of geranium, pelargonium and other geraniaceae and acts as a formidable insect repellent. Flies and mosquitoes will inevitably be kept at bay once this diffuser is in use. 

Do you want to diffuse a gentle fragrance over the long term, facilitate concentration and improve the working atmosphere, refresh and purify the air, personalise the atmosphere of a room (conviviality, freshness, aphrodisiac, Christmas atmosphere, etc.), embellish your room with a sober and elegant decorative object? This diffuser will fulfil all these uses.

What attracts flies in the home ?

They are called houseflies for a reason! They easily enter our homes. Why do they do this? Because our homes are cosy! In addition to the warmth, they find :

- Our dustbins : a multitude of organic waste more or less within their reach

- Fruit and vegetables : flies love sugar

- Pet food : the kibble of our dear companions is a feast for flies

- The presence of animals in the vicinity : cows, horses, sheep... all animal farms are real fly nests as they feast on their excrement, among other things.

Flies are not dangerous in the strict sense of the word, but it is better to protect yourself from them for the sake of hygiene.


Instructions for use

Remove the cap, insert the sticks into the bottle. The geraniol will diffuse naturally in your room. The repellent effectiveness against mosquitoes and flies is obtained after 24 hours of diffusion.

Efficace et esthétique


contre moustique

Fait son effet. Odeur pas désagréable.


Très bien

Discret, plutôt esthétique et permet de tenir à l'écart les moustiques.


diffuseur moustique Otentik

Ok. ça marche bien. Dommage par contre d'avoir à racheter l'ensemble quand c'est vide. Il faudrait pouvoir proposer une recharge.



odeur discrète mais suffisante pour tenir à distance les moustiques. Attention à ne pas placer dans une pièce ventilée, sinon ça marche pas



Que dire de plus quand on voit les moustiques tjrs présent



Emballage pratique, ensemble très simple, facilité d'usage mais senteur du produit très peu développée; efficacité peu réeelle; hélas; cela ne m'empêchera pas de rachetr sur le site
