Swiss Mosquito Network

In 2017, the Swiss Federal Office for the Environment decided to establish a unified, coordinated and integrated national surveillance programme to combat the spread of exotic, invasive mosquitoes in Switzerland. The goal is to inform the citizens, systematically monitor invasive mosquitoes and, if necessary, suggest control measures with use of insecticide products.

For further information, please, contact the regional reference offices at the bottom of the page.

Native mosquito species are not considered here because, although sometimes annoying, they involve problems and surveillance and control strategies other than invasive mosquitoes.

Information for the public

Invasive mosquitoes can be a particular nuisance for citizens and can be carriers of various exotic diseases, if these diseases are present on our territory. Knowing the invasive mosquitoes and how to control them reduces both uncomfortable bites and the risk of mosquito-borne diseases.

Mosquito surveillance

Since 2013 a national surveillance programme has been established along the main traffic routes in Switzerland and several cantons have initiated a local surveillance and control programmes. All data will be soon made available to the public, officials and scientists through the Centre Suisse de Cartographie de la Faune.

Mosquito control

The cantons are the responsible authority for the control of invasive mosquitoes, based on regional monitoring data. Usually these fight measures are carried out on public grounds, while on private citizens are encouraged to adopt simple control activities.
