It is indeed an unprecedented day of joint mobilization against the tiger mosquito throughout Lake Geneva with the authorities on both sides of the border. It is the Environment Commission of the Lake Geneva Council (chaired by Ain) who came up with the idea.

Goal ? Share each other’s experiences in information and monitoring of the tiger mosquito.

Originally from South-East Asia, the tiger mosquito has recently appeared in the Lake Geneva region. The tiger mosquito has been installed in France since 2004. As of May 1, 2020, it is established in 58 departments.

In the summer of 2020, it was spotted in Switzerland, in the canton of Geneva and in the Chablais Valaisan as well as in France, in Ain and Haute-Savoie.

A small aggressive mosquito that grows near homes

Even if it has not yet settled everywhere, it is important that everyone understands their role in coping with their arrival on the territory and fighting against its proliferation “.

As a reminder, the tiger mosquito, with its body and legs striped in black and white and whose size is between 5 and 10 mm, is particularly harmful. It basically stings the day.

It is especially a vector of diseases such as dengue, chikungunya or Zika, in certain cases, when it bites an already infected person.

You should know that it grows especially in gardens, on terraces, balconies and even in cemeteries. Like all mosquitoes, it needs water for its eggs and its larvae and pupae.

He likes to colonize the various and varied containers that fall under his feet (watering cans, bowls / cups under flower pots, rainwater reserves, etc.).

Finally, in summer, the development time from egg to adult lasts between 8 and 12 days. The lifespan of an adult being about 4 weeks, several generations follow one another during the season.

Simple actions to prevent its proliferation in the Lake Geneva basin

You will understand, depriving it of water prevents its development. Knowing that 80% of favorite places are near homes, it is therefore necessary to empty, cover, or store any container.

At the dawn of the summer season, the 3 million inhabitants of the Lake Geneva basin are therefore called upon on June 1 to adopt the same good reflexes.

This general public information video is available to the general public, on both sides of the border, as a “little reminder”.

The stake is “to anticipate the stable establishment of large populations of the mosquito and to manage control using appropriate means that are not very toxic to the environment “.

Think you’ve seen a tiger mosquito? Do you want to report it? You can do this and help more accurate monitoring of the distribution of the species.

France and Switzerland respectively use two reconnaissance and surveillance systems in sensitive areas. The entire population can participate in spotting the tiger mosquito by reporting its presence on or

Be careful, not everything that flies is mosquito, and not all mosquitoes are tiger mosquitoes “ the experts warn not without humor.
