A mosquito control operation will take place on the night of Tuesday, October 20 to Wednesday, October 21, 2026, between 11 PM and 6 AM, in the commune of Puy-l'Évêque. This intervention follows the detection of the tiger mosquito, a potential vector of viral diseases.

Following the stay of a person carrying a virus transmissible by the tiger mosquito (chikungunya, dengue, or Zika), an entomological survey has confirmed the presence of this vector in its adult stage in the commune. Consequently, a mosquito control operation is scheduled.
The treatment will be carried out by the operator ALTOPICTUS, mandated by the ARS Occitanie, and will be conducted from a vehicle (pickup truck) and potentially by a pedestrian treatment. Weather conditions may affect the exact date of the intervention.
Affected residents have been informed by mail. The decrees governing this action are available on the ARS Occitanie website and on Legifrance.fr.
