Tiger mosquito proliferation prompts local health measures in Île-de-France

The tiger mosquito (Aedes albopictus) is increasingly prevalent across the Île-de-France region, prompting local authorities to implement surveillance and prevention measures. This invasive species, characterized by black and white stripes, thrives in urban environments by breeding in small amounts of stagnant water found in flowerpot saucers, gutters, and water collectors. While primarily active during the day, the mosquito can transmit viruses such as dengue, chikungunya, and Zika.

In Argenteuil, Mayor Georges Mothron announced the deployment of over 60 passive egg traps in local schools following successful experiments that showed a significant decrease in reported bites. These traps capture female mosquitoes using adhesive surfaces without the use of harmful insecticides.

In Villiers-sur-Marne and the broader Territoire Paris Est Marne & Bois, authorities are working alongside the Agence Régionale de Santé (ARS) to monitor the population. Residents are urged to adopt preventative habits to eliminate breeding sites, such as emptying containers that hold water, covering water reserves hermetically, and maintaining gutters to prevent stagnation.
