The Tour du Valat's position

To reconcile a decrease in the nuisance caused by mosquitoes in the inhabited zones with the conservation of the exceptional natural heritage of the Camargue, the Tour du Valat demands that:

  • Any mosquito control project in the Camargue must be carried out within the scope of an action plan developed by the local government agencies and include in particular the hydrological management of the habitats, a study of the probabilities of the dispersion of mosquitoes, as well as the protection of sensitive habitats with a high natural heritage value,
  • This action plan must place importance on information dissemination and the concertation of the local population in order to plan and support any mosquito control operation envisaged in the Camargue. in particular, the inhabitants of the Camargue must be clearly informed of the purpose of the operation ("for comfort" or public health), the means envisaged, as well as the environmental and economic costs of these operations,
  • The use of insecticides, under the supervision of a public authority, must be envisaged with the single objective of limiting the nuisance in the inhabited zones; in the event of mosquito control in the Camargue using insecticides, the sensitive and protected areas with a high natural heritage value must not be exposed to any insecticides if there are any risks of impact for these habitats and/or the species that live in them,
  • Only Bti must be used, in levels of concentration that do not exceed 3l/ha and in time frames enabling the impacts on the non-targeted fauna to be minimised,
  • Information pertaining to the list of products, dosages, zone treated, and dates of dusting for any operation carried out by the public authorities must be accessible to all,
  • A broader study on the effectiveness of CO2 traps must be completed and, in the event of positive results, the public authorities must provide funding so that private consumers can acquire this equipment,
  • Anti-Chiromonid treatments for reasons of comfort must be stopped and the population must be made aware of the non-biting nature of this insect and its essential role in the food chain,
  • Long term studies, enabling the impact of the operations on non-targeted fauna (other than mosquitoes) to be evaluated, must be carried out by independent organisations.
