This is not enough to completely reassure this Thônesian resident. who confides: “If we really spray my garden with this product, I would no longer dare to eat my salads!”
“Counterproductive” to spray all

Such a demoustic operation remains exceptional. decided on the basis of specific criteria (population density of the tiger mosquito, virus geneva: test sanitary alert plan rate in the patient’s blood, etc.).
Gottlieb Dandliker, responsible for invasive exotic species at the Ocan, in front of mosquito traps. He points out that these work, but it is not the way to use in priority. “The most important thing is to act on laying sites.”

An operation like that of today is only useful if it is carried out in the presence of a health risk. to remove individuals carrying exotic diseases.

Eliminate the laying sites of the tiger mosquito against proliferation
The fight against the expansion of the undesirable. it is practiced with other weapons, involving private and communities: the removal of small accumulations of water and the dispersion ofantilarves, that the canton puts freein the sewers to kill the larvae. “This is the most important measure, the traps are not enough,” insists Gottlieb Dandliker.

In Geneva, last year, 50 cases reported from Dengue were identified, against 27 in 2023. Only twenty was considered at risk, because intervening geneva: test sanitary alert plan during the Mosquito activity period from May to October. A single case of chikungunya was detected at the end of 2024, and two some some were reported this year. For the Zika, only one case was reported in 2024 and none since the start of the year. The consequences of these exotic diseases can be serious. to name only fetus malformations for zika and painful sequelae for dengue.
The cantonal doctor’s service recommends that travelers return from a destination where CDZs. are present to protect themselves from mosquito bites for fourteen days after their return by applying a repellent.
