The Concept

Make use of mosquitoes’ instinct in order to trick them and decimate their descendants by saturating nuisance places with trapped mosquitoes’ nests.

This biological fight against grubs consists in continuously giving mosquitoes the ideal trapped laying place so that they could quietly lay down their eggs and thus stop their reproduction cycles.


This concept of trap is patented and an international brand known as “VAEDES” as well as the design and logo have been registered.



40 liters two-part pond (in kit-form) – Plastic injection molding – Black color – Soft and anti-UV treated

It can be placed or buried on the soil or in a garden.

It has been made with approximately 2.5 kilos of raw material (plastic)

This pond is perfectly appropriated to the entomological plane.

The trap is supplied with an instructions leaflet. It has a heart-shaped bowl which design is pleasant and feng-shui.

The funnel effect

When the traps are well located, as near the adjoining boundaries, mosquitoes that move within a radius of several dozens of meters are lured by the system; this is why a great number of eggs are destroyed.


The scientific ratification of the idea

This concept is an association of scientifically-recognized data.

It is scientifically proved that the mosquito lays in the first watering place which suits him; this is why it is recommended to avoid the presence of sub-pots, toys, covers and all other black colored plastic things, such as tires, containing stagnant water. Tires are places that favor female mosquitoes for the oviposition (laying eggs)

It is scientifically proved (REITER 2007) that when grubs’ nests are too small (less than 300ml), the mosquito is able to divide its clutch and find another watering place which would offer better  conditions for the rest of its clutch. The more the watering place is small, the more the quantity of laid eggs will be small, hence the necessity to have more and more sizeable traps (40 liters).

Mosquitoes know instinctively that the more the grubs’ nest is small, the less the grubs will have chance to survive.

It is scientifically proved that AEDES AEGYPTI mosquitoes prefer watering places containing plants such as bamboos, hence the necessity to place on the surface of the trap some bamboo leaves (Ficus leaves also give good results)

It is scientifically proved that unlike chemical substances, grubs could never resist fishes!

It is scientifically proved that the mosquito can’t detect the presence of the biological agent and lays despite the presence of fishes.

It is scientifically proved that at first the mosquito emerges from an egg and then becomes a grub.

It is scientifically proved that AEDES AEGYPTI mosquitoes pass on the virus to its eggs, this phenomenon is known as a vertical transmission; hence the necessity to fight against grubs in order to collect eggs infected by viruses.

It is scientifically proved that the insertion of predators in grubs’ nests gives good results; as in Vietnam where good results were obtained thanks to the insertion of predators in rainwater storehouses.

“Some of small-sized shellfish (from COPEPODA Order) attack during the first larval phase. In Vietnam, they have been used on a large scale in rainwater storehouses to fight against AEDES AEGYPTI mosquitoes; the results were encouraging” (page 13)


Why results are so good?

Destroy the nests or avoid mosquitoes to access to water oblige them to find other laying places; but this only shift ineluctably the problem.

By inserting predators in nests, mosquitoes keep on laying their eggs in nests which become traps because the descendants of mosquitoes are eaten by the predators.



The fight against carriers-insects is a major concern for the health departments of the concerned countries. The dengue fever, which is a viral disease passed on by AEDES AEGYPTI mosquitoes is, just like the malaria, one of the most important disease affecting human populations of the intertropical regions.

Since few years, New-Caledonia has to face a massive outbreak of cases of dengue fever. In order to limit at its maximum the spread of this disease, it is essential to limit; first of all; the carriers, that is to say the AEDES AEGYPTI mosquito.

During many years, the supervision of mosquitoes was realized by the massive use of insecticides, having for targets adults or grubs. In the first years of their use, these methods were very efficient. Now, we know their limits (REITER, 2007)

The aerial spreading of insecticides is from now on less systematic because it presents several disadvantages such as the selection of mosquitoes populations resistant to insecticides; the contamination of natural environment by huge quantities of insecticide molecules which are highly toxic for a wide and varied range of invertebrate animals, and finally, some of the mosquitoes which are inside houses are not affected by these insecticides.

At present, all the departments implied in the fight against mosquitoes agree that a more global approach combined with a reasoned chemical fight, the reduction of grubs’ nests and the use of auxiliary insects is needed. These auxiliary insects are generally grubs’ predators.

These methods implying a massive participation of the inhabitants residing in the concerned regions showed significant positive results, particularly in Vietnam thanks to the use of a varied range of grubs’ predators such as copepod insects.

The method proposed by the Company LSMconcept “La Solution Moustique” to decrease mosquitoes’ populations proceeds in two phases. At first, a visual search allows to list all the potential grubs’ nests present in the area. These nests are then destroyed; for example: the containers filled with stagnant water are emptied.

This phase of decrease of the grubs’ nests is followed by the introduction of tubs containing grubs’ predator fishes. These black-colored plastic tubs are filled with water and a part recovers half of the surface. Besides fishes, some plants’ leaves (which are deteriorating) are added to water in order to make the environment more attractive for gravid mosquitoes-females. In fact, it is a matter of recreating a very attractive laying place offering ideal environmental conditions for gravid mosquitoes-females.

The predatory fishes that were retained by the persons working for the Company “La Solution Moustique” are the guppy and the gambusia. These species are grubs’ predators-fishes.

The species has already showed its efficiency in programs for the fight against mosquitoes’ grubs.
