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.

Introducing the mosquito repellent

mosquito breeding ground stagnant water

Our ready-to-use Mosquito and Flea Repellent is the ideal solution to fight against adult mosquitoes but also mosquito and fly larvae.

Composed of a powerful active ingredient of natural origin : Geraniol (included in the list of Biocides in Directive 98/8/EC), this product will act by suffocation and dehydration (particularly on chitin, exterminating larvae and eggs in the process)

This product, with its anti-mosquito and larvicide action, will be effective in humid, aquatic and plant environments (hedges, shrubs, flower pots, etc.) and on all types of mosquitoes, including Tiger mosquitoes (Aedes albopictus, the mosquito that carries Dengue fever and Chikungunya).

It is non-toxic to the environment and to other inhabitants of the breeding grounds. It can therefore be used both indoors and outdoors in complete peace of mind.

Eradicating a larva today means eliminating a complicated flying mosquito tomorrow... Think about it !

Its composition

Geraniol TP18/TP19. CAS No. 106-24-1 dosage 0.2%. water solubilised essential oil, vegetable dispersant, preservative. Ready to use solution.

Focus on the key asset


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 (which has been removed from the list of authorised insecticides by the European Directive).

It is obtained by fractional distillation from Cympobogon Winterianus Jowitt by extracting all impurities without any chemical means.

Geraniol in aqueous solution acts in two ways on insects, whatever their stage of metamorphosis (egg, larva, adult): by suffocation and by dehydration. Geraniol is one of the best larvicides on the market.


Advice for use

The treatment should be carried out in the pre-season or as soon as the first mosquitoes appear.

To destroy all egg-laying and larval habitats, spray on stagnant water, flowerpot saucers, water holes, or any other place where mosquitoes develop.

Be careful, you will have to repeat the operation after each rain or watering. 

N.B. : Be careful when using this product in ponds or pools containing fish. Geraniol is a substance that can be toxic to aquatic organisms and cause long-term adverse effects. This product is to be used on stagnant water, puddles and other puddles where fish are not present.

What surface area can be treated with this bottle ?

This 500 ml bottle is ready to use and will treat approximately 10 m².

Treating stagnant water for mosquito larvae 

Places to monitor and treat for prevention

Mosquitoes can lay eggs anywhere. A bucket out of the way that you've left to fill with water for too long, plant containers. Here are some ideas of places to monitor and treat for prevention :
- Balconies,
- Terraces,
- Patios,
- Gutters,
- Shrubs/surrounding vegetation (especially Cypress or Cedar trees which are particularly popular with Tiger Mosquitoes),
- Rainwater drains,
- Crawl space,
- Ditches and drains,
- Tree hollows, ...

Developmental stages of the mosquito

As always, in order to achieve effective control, it is important to have good bio-ecological knowledge of the target.

Eggs are laid either on a moist substrate (Aedes) or on water (Culex, Anopheles).

In the first case, the eggs deposited on flooded soil can remain viable for several weeks, months or even years. They hatch in the first few hours after being submerged, provided that the temperature and photoperiod are favourable. In the second case, hatching usually takes place one to two days after oviposition.

The larvae
All larvae live in water, without exception. The larval stage lasts from one week to several months, depending on the water temperature. The higher the water temperature, the shorter the duration of the larval stage. After passing through four successive stages, they transform into nymphs, which are also aquatic.

Unlike the larvae, the nymphs do not feed and are therefore insensitive to ingestion insecticides. Nymphs will emerge after 2 to 5 days: the flying adults.

The adults
Most species are nocturnal (Culex, Anopheles) to crepuscular (Aedes). The males, whose longevity is relatively low, remain close to their hatching site. The females can travel several dozen kilometres with the help of the carrying winds. Aedes are the best flyers and it is not uncommon to find them causing a nuisance sometimes 30 or 40 km from the hatching site. The flight range of Culex does not seem to exceed 2 to 3 km, that of Anopheles is slightly greater.

In order to effectively combat mosquito nuisance, it is therefore necessary to act from the larval stage. This is what you can do with our ready-to-use anti-larvae and anti-mosquito product Penn'Ty Bio.
