Montpellier: solutions, activities, methods of reproduction… the mosquito hunt is on

EID Méditerranée, an expert in mosquito control, deciphers this phenomenon, while the huge numbers of mosquitoes are destroying the lives of holidaymakers.

Humidity and heat: the mosquito’s favorite cocktail! Since the beginning of the month, mosquitoes have been rife along the entire coast and in some counties of Montpellier. And for good reason… Rains in early July led to a return of water and moisture spots. Climatic conditions are especially appreciated by our seasonal troublemakers.

Faced with bites and itching, many people try to find individual solutions. But to understand the phenomenon, it was necessary to know how it works and how it reproduces.

Mosquito control at home…

“There are two types of mosquitoes: the tiger mosquito and the swamp mosquito,” Christophe Morgo, president of EID Méditerranée explains. By 2004, the tiger mosquito moved very little,”about 100 meters”, the president said. Much more common in Montpellier, this species of mosquito grows near all points of standing water: pitchers, children’s toys or even watering cans… To stop its breeding, the EID recommends removal all “small accommodation”. A simple way to control mosquitoes yourself at home.

Swamp mosquito… On the beach

Another species is in full swing. Mosquitoes come from swampy areas, which means swamps. More present on the coast, “these mosquitoes are capable of spreading over several kilometers,” informed Jean-Claude Mouret, Mediterranean operations coordinator at EID. “IThey can cover 25 to 30 km when conditions are favorable for them”, Christophe Morgo adds. And thus quickly invaded the surroundings, including the city of Montpellier…

Two methods of treatment

To combat their proliferation: two strategies. Prophylactic insecticide treatment is carried out while the mosquito is still in its larval state. This makes it possible to be effective almost immediately. “It is the most effective treatment. “, Jean-Claude Mouret emphasized. The only condition: the wind should be less than 20 km/h.

Biopesticides and pollution

In total, about 25-30% of mosquitoes develop due to standing water. It was in the 2000s that a new biopesticide appeared, called “BTI”. This is a type of bacteria that attacks the intestinal tract of mosquitoes. According to Jean-Claude Mouret, operations coordinator for the Mediterranean, the treatment used is quite safe for other species. Especially when used in moderation. Its danger to humans is still difficult to say for sure. A nuanced opinion of environmentalists, whose use of “BTI” still costs biodiversity.

The second treatment, the impurity killer, is very special. It acts as a last resort against larvae. “The last activity started in 2015, notify the dispatcher. It can only be done on the coast, using a salvage vehicle. “
In addition to limiting proliferation, this treatment also limits the migration of mosquitoes into the city. “Because in Montpellier, we can’t work from home. “

On the coast, between need and relevance…

For this last special treatment, the EID will perform on-site diagnostics at the request of the municipality. It is based on both people’s opinions and observations made in key places. In this process, conformity is assessed and then analyzed. If it is proven conclusive, the operation is initiated.

Therefore, last Monday morning, a special mosquito control operation was launched at Grau-du-Roi, opposite La Grande-Motte, by EID. Much awaited, it was done after the first rejection, due to strong winds.
