The mosquito, carrying diseases
Who has never been confronted with the presence of mosquitoes? This pike-sugar insect can become a real problem in some areas, so much their number to increase. Find in this folder a set of answers and products that will allow you to fight this invasive insect at best.
Latin name: Assex pipiens, culiseta annulata, aedes punctor
Family: Fucked up
Size: 4 to 7 mm
Location: all habitats
Period: spring to fall
What you need to know about the mosquito
Everyone knows or thinks they know these small insects a few millimeters, which import our summer evenings.
In france, there are 67 species (of which four are willingly pumping our blood!). but there are at least 2500, both in polar regions and in the equatorial forest. therefore man is not the only vertebrate concerned by these attacks.
The female prefers a temperature between 15 and 30°C, with a relatively high humidity.
These conditions are mainly found during the summer months, late afternoon and after sunset, as well as early morning and after rain.
After mating, the female, which is the only one to sting, needs protein (sang) to lead her eggs to maturity. The male, for him, kills the flowers to feed.
For the place of deck, the only common point between different species of mosquito is the need for water. all water points, except the constantly agitated sea, can be used to deposit the eggs. the mares of course, but also the watercourse edges, the saucers of the flowerpots, the cans of cans or the footprints in the ground are all suitable places for the deck.
In general, eggs are deposited individually, but they are also attached to each other, forming barrels or small rafts floating on the surface. Depending on the species and the period of the year, the outbreak occurs after a few hours or months. some mosquito eggs can withstand a drought period of three to five years.
The evolution of the larva (from 2 to 12 mm) occurs in the aquatic environment. it is mobile and breathes on the surface of the water either directly or through a respiratory siphon. it finds its food either on the surface or at the bottom of the larval gite. When it has completed its growth, the larva becomes less active and transforms into a nymph, absorbing air through its respiratory tubes.
When the temperature is favourable, the entire cycle from the egg to the adult stage can last less than 10 days.
On average, females weigh 2 to 3 generations.
At the end of the summer, the adult mosquito can winter in all premises, even unheated.
Females are especially attracted to certain odors from the host: sweat, clean smell of the skin, steroid amino acids, urine, etc. the carbon dioxide (co2) expired by the host would play an important role in triggering the fly in a room.
The species, the weather conditions, their energy reserves, unfavourable conditions, ... are determining factors on the distances of these insects. a mosquito that stings you can come from a few dozen meters or a few dozen kilometers.
How does the mosquito spot his host to feed ?
Mosquitoes identify their hosts with a highly specialized recognition system, called choirs, located on the antennae. these receptors are sensitive to different parameters:
- perception of heat
- infrared radiation
- day/night vision
- Chimio-olfactory (perception of specific molecules and odours)
Some mosquitoes spot the co2 that is emitted during normal expiration, or important as a result of physical effort, in a perspiration odor. specific data (osmolarity, salinity, chemical composition) confirm to the “suceurs-piqueurs” as the mosquitoes that they are well sucking blood and that they can therefore feed themselves. the accuracy of the sensory perception is related to the number of choirs. They also serve the needs of sexuality. the mosquito that lives more or less away from its host (like a chip for example) is equipped with about 5000 antenna receivers.
The mosquito, a vector of diseases
Mosquitoes are vectors of diseases, that is, they only carry the pathogen. This is the case for malaria, a disease that is responsible for almost a million deaths a year, and for malaria, transmitted in europe by mosquitoes of the anohele genus.
In france, for many years, mosquitoes no longer theoretically present a danger to man, which has not always been true since in the 1940s, the region of the herault was nicknamed the "fever country !
1. wear long clothes
Cover yourself with clear, white or khaki dyes by taking care to cover your wrists, ankles and neck. Also think about spraying on your clothes, our special textile insect repellents (Penntybio or Aries)
Avoid odorous shampoos, perfumes and after-shave lotions that will attract them.
4. prevent any approach
Install somenets on all windows as soon as possible. deal with our repulsive flying insectsOr Habitat all entrances, beddings, sailings, mosquito nets and all surfaces you want to protect.
5. treat ambient air
Close doors and windows and spray in ambient air or directly on mosquitoes orl'insecticide Ecodoo, either flying insecticide Aries. finally, in the field of fumigation:thefogger habitat Biovétol. this product will give excellent results on this type of insects. insecticide based on plant-based assets (pyrethre + géraniol) for the background treatment of habitat. very volatile, the solution is deposited in the smallest corners where pests and insects are located. immediate action. 3 different formats exist: 75ml for treatment less than 15m2, 150ml, for treatment less than 30 m2. Finally, 250ml, for treatment greater than 30m2.
6. keep them remotely
Mosquito hates very disaggregated areas. the airflows caused by a fan will help you keep them remotely. products also exist. for this, several solutions:
a - diffuse our special mixture anti-moustic (synergie of essential oils) or lemongrass. This will keep them remotely.
b - the anti-moustic electrical socket Aries with its concentrated mixture of géraniol will keep them remotely throughout a night.
c - our anti-moustic spirals will allow you to keep mosquitoes away effectively. The smoke that consumes these spirals is composed of pyrethre. the mosquitoes will be immediately disturbed and will pass their way, see if they insist !
7. remove larvae
Remains an important point to limit the population of mosquitoes: to remove near the house all stagnant water points or apply our anti-larve and mosquito concentrate.
8. relieve mosquito bite
If the mosquito has been stronger than you, natural products exist to relieve the itching that causes its bite. they exist in several forms.
Electric anti-mosquitoes !
Electrocutors : since the mosquitoes are not specially attracted to light, this device is very uneffective.
Ultrasound emitters : this device can be effective in removing dogs but a priori, not mosquitoes !
The only valid electric anti-moustics remain those on power socket. That of the mark Aries works in soft heat. A buffer of a concentrated mixture of géraniol and lemongrass, slips the buffer into the case. branch and product diffuses for several for effective protection.
Conditions of mosquito proliferation
The mosquito requiring heat and humidity to reproduce, many and continuous rains in spring, associated with mild temperatures, thus promotes the proliferation of mosquitoes.
If with average temperatures, it takes about three weeks to pass from the egg state to that of adults, by high heat, only about ten days are enough to bring out an adult insect.
Mosquito does not reproduce in current waters and rarely in permanent mares, where many predators are sufficient to eliminate them, but in stagnant water that can warm up quickly. For example, water pockets, following temporary floods, in the hollow of tree trunks, leaves, plastics and other excavations. In urban areas, rainwater waste pickers, gutters, flower pots, bags for abandonment, tires, rainwater eyes, are all places for the reproduction of mosquitoes.
How to fight against mosquito ?
This begins with the systematic removal of the stagnant waters likely to be breeding grounds. this operation being easier in urban than in natural environments.
1 - Some simple operations
Disposal of residual flakes, retrieval of containers, removal of plastic wastes, removal of blossom pots in wet times, lamping of gutter feet and pit holes, cover of rainwater waste pickers and other containers. containers that cannot be covered must be drained every 5 days to avoid a complete breeding cycle.
The larval gite of predilection is constituted by the septic pit whose adult mosquitoes escape by the aeration pipe. it's enough grill the latter and its upper orifice and to remove the mosquito corkscrew every year that could possibly have formed.
Flooded cellars, as well as sanitary vacuums must be dried by adequate automatic devices.
Small holdings or water collections will be removed, including old tires, various receptacles, car carcasses, etc. vidang them at least every week.
This list is of course not exhaustive.
2 - in addition
Insecticides with active molecules can also be used:
Massive use of insecticides is not without consequence on our environment. most are toxic, see very toxic, for the aquatic environment and dangerous for cold blood animals. Think twice (see 3!)
Our other advice on the treatment of mosquitoes
1 - Respect the buffer zones defined for the protection of the aquatic compartment.
2 - Inhibit treatment in the event of heavy rainfall risks.
- preferably treat between sunset and sunrise:
- mosquitoes are more active at night,
- the pyrethrins are quickly destroyed by the sun (15 minutes in full sun,),
- less risk of destroying "useful" insects.
3 - Treat only if the weather is ready (low wind, absence of rain, high temperature).
4 - Spray preferably in the form of fog (very fine droplets), which will increase the duration of the suspension in the air of the product and thus its efficiency. the mosquito must return to contact with the insecticide at the moment it is sprayed.
Whatever insecticide you will use, it will only act on the adult and not on the larva, so it will be necessary to repeat the treatment every 2 to 3 weeks. You can also treat stagnant waters, to destroy larvae, with a specific product such as bti (i.e. bacillus thuringiensis israelensis). Be careful not to abuse this product, there would be accustomance (study in camargue).
Concerning the concentration of our insecticide 4j, even if we found that the mosquito was destroyed with a concentration of 1.5%, in the form of fog, it will be better to increase the concentration to 3% see 5% (it will depend on setting the nozzle of the sprayer) in order to keep the same amount of active ingredient in contact with the mosquito.
Mosquito and chikungunya
Report of the afsset of 15/10/2007 concerning the fight against the chikungunya epidemic using various insecticides including pyrethre.
We only retained this report from the pyrethre section, but you can find the entire document on https://www.afsset.fr .
- Effectiveness :
- chemical family of natural pyrethrins, close to that of deltamethrin (synthetic pyrethrinoids)
- low resistance cases; rarity due to the nature of the substance: mix of 6 active isomers
- used at 5 to 10 g/ha
- Toxicological properties :
- very little toxic by skin
- non-irritating to skin and eyes, non-sensitive
- non-mutagen, non-reprotox, non-teratogenic
- oral carcinogenic effects in the animal but not transposable to man; neurotoxic effects of minimal grade in the animal by oral
- cases of awareness-raising (eczema, asthma) in a professional environment
- Physico-chemical properties and behavior in the environment :
- soluble in water
- very rapid degradation in all environmental compartments
- strong affinity of the pyrethre for organic matter (tendency of soil retention and high adsorption on suspended particles in water)
- high bioaccumulation potential for pyrethra with potential bioaccumulation risk in trophic chains
- moderate volatility of pyrethre
- Ecotoxicological properties :
- very toxic to aquatic organisms
- low pyrethre toxicity for birds and high for mammals
- very toxic to bees because of their insecticide nature
- Risks to man :
- the risk associated with exposure to pyrethra during its application is acceptable to operators and persons present nearby subject to recommendations of good practices in the use strategy.
- Risks to the environment :
- exposure levels determined during this work lead to risks associated with the use of pyrethra of concern for the ecosystems studied.
- Strategy of use :
- in the absence of a specific analysis of adjuvant risks, prefer products formulated in phase
- in the case of a need to alter treatments, use pyrethre based products
- to implement appropriate protocols for applicators by focusing on:
- the buffer zones of 25 m and 50 m defined for the protection of the aquatic compartment
- to prohibit treatment in the event of abundant rainfall risks that can result in the run-off of substances to water points of greater importance
- to protect hives during treatment periods by a beekeeper alert system
Plants to repel mosquitoes
If you are looking for a method to keep mosquitoes remotely in addition to your usual products, some plants can help you.
Incontournable in anti-moustic plant, it is even used in essential oil in certain anti-moustic products. However, it is necessary to nuance its power, it only acts provisionally. This is why the European Union has banned its use as an insecticide.
2- the pyreethre of Dalmatia
This flower contains a natural insecticide: pyrethrin. this substance attacks the nervous system of insects (neutoxic action). It is also with this plant that a good number of insecticides are made in penn'ty bio.
Mosquitoes do not appreciate its smell, and as a bonus it is perfect infusion.
4- Cat grass
Also known as "catary", this plant of the same family as the mint contains nietalactone, an organic compound that has the effect of pushing the mosquitoes. this plant also acts as a cat bait.
Very easy to maintain and grow, the basil, except that it will be extra to aromatize your dishes, will have a repulsive effect on mosquitoes. So you can cultivate it in a parterre just under your windows or in pot inside.
Several flying insects, such as wasps, bees or mosquitoes, have the smell disturbed by lavender. In essential oil, it also has soothing and relaxing virtues.
7- the rosemary
In addition to fleeing several species of insects, rosemary is also an excellent remedy in case of bronchial coughs, ideal for winter.
Frequently asked questions about the mosquito
Q: Which insecticide and repulsive products would advise me against tropical mosquitoes (dengue). ? I live in guadeloupe and I am looking for a safe vaporizing bio in my children's room and in the rest of the house ?
R: We have various repulsives on our site but no product can guarantee you zero mosquito in a room.
Q: We are in the var and there is stagnant water under the wooden terrace...I would like to treat mosquito larvae without harming the small lezards that remain there... which product do you recommend?
R: In this case, you can use our concentrated anti larvae and mosquito solution. No risk to lizards. However, snakes will not appreciate the géraniol contained in this product.
Q: Do you have a natural insecticide that is totally effective as a protection against malaria (days of one month planned in Thai at parties)? (I'm trying to avoid deet-based insecticides and other harmful substances)
R: In body protection, we have the effective anti-moustic lotion also in tropical environments. you will find this product and many more on our site. some is the product and for good body protection, it is necessary to renew the application several times a day.
Q: I want to use one of your outdoor insecticide on plants and bush to eliminate mosquitoes. Is it possible without damaging my plants? if yes what product to use ?
R: You cannot eliminate mosquitoes by treating plants. At best, you will kill those who will receive the product at the time of treatment, the insecticide 4j to 2% will close the case. treatment of mosquitoes is carried out on water bodies to kill eggs and larvae and not on plants.
Q: I am currently looking for an extremely effective repulsive insecticide against mosquitoes? I live on the edge of the loire and I let you imagine the summer nights I am invaded by mosquitoes. I fell on your site and it seems interesting only to me I have a question that is your product can be applied on hedges, flowers, trees finally any object outside?? Is it effective on long-term outdoors even with several rains ?
R: Our repulsive is based on floubilized essential oils, which means that it will not hold the rain. There is very little product that keeps the rain, which is why farmers are forced to retire after a rain !
Q: Demand: Are the products you are proposing effective on the most common aedes species on the northern regions of the ledge (aedes rusticus, cantans and vexans)? alain boyer pdt of the mixed dub and marne whispering union
R: No idea, but a priori our insecticides are not selective so effective on all insects!
Q: My 2-year-old daughter has been allergic to mosquito nets since the age of 5 months; It's a limestone all the more because we live in the antils; My questions: Are your repulsives effective against the antillean mosquitoes the famuex aedes agypi deplus could she wear your repulsive bracelet at its age? It makes me some allergic reactions to some anti mosquitoes (exema) that I now mistrust. Thank you for your answers
R: For this age, most anti-moustics are not recommended. We no longer market the bracelets but anyway it would have been too big. we can offer you anti-moustic lotion Aries for children.
Q: We are looking for a powerful whisper for large surfaces that are not harmful to water bodies (fish, frogs). a vaporiser par vaporiser auto tracté
R: We currently have nothing to offer you as a product of this type.
Q: I have to impregnate my mosquito net with a repulsive insecticide. which insecticide can I use? at what frequency must the net be re-impregnated. Thank you for your answer.
R: The impregnation of the nets is usually made based on synthetic products composed of allowshrine, with a longer duration of action. You will not find in natural durable mosquito net treatment products, the remanence they offer is a little short. you can however use our repulsive insect habitat which will offer a barrier of several hours without problems.
Q: In the southwest, it is difficult to stay in our garden because of the invasion of mosquitoes. Is your insect repellent effective outdoors by spraying on the lawn and nearby plants ?
R: No product resists very long the sun. You'll have to retire very regularly !
Q: Then how do we protect ourselves outside against these invasions (without using helicopter treatment as a camargue!!)?
R: You must take the technique of the island of the meeting or then individual protection.
Q: I have close to the house a pool of accreditation how and with which product then I treat to eliminate mosquito larvae
R: We products being soluble currently we have nothing to offer. You need a non-soluble insecticide that will float on the water. may be neem oil.
Q: I'd be interested in the anti-moustic bracelet.
R: At the moment we stopped marketing this product following allergic reactions from some customers.
Q: What is the shelf life of the product "anti-moustic and flying insects" (and other products in the range) ?
R: Each product at a specific time, most often it is 2 years after manufacture of the product.
Q: Is what your insecticide 4j to 5% is dangerous to animals. Indeed with the rains we are invaded by mosquitoes in our garden, yet there is no stagnant water but the soil being water-filled I think the mosquitoes have developed. Can we put this dilution insecticide to 4% on grass and trees ?
R: Pyrethra-based insecticides are only dangerous for cold-blooded animals such as fish. Yes, it is possible to put this dilution insecticide to 4% on grass and trees. However, have in mind that it will kill all insects that will be affected by the product. It is therefore best to do so at night falling, time or go out mosquitoes and lay down other insects.
