Measures to combat the tiger mosquito are effective and are continuing in the canton of Vaud. According to the authorities, it is possible to slow down its spread, or even eradicate it in certain cases. The population is always invited to collaborate.

Following the 2023 campaign, the canton of Vaud identified populations established in the municipalities of Nyon, Préverenges and Lausanne. It also received new signals in the municipalities of Crissier, Bussigny, Pully and Vevey, it said in a press release published Tuesday.

Reason to rejoice, during the year 2023, the town of Bourg-en-Lavaux (Cully) got rid of the tiger mosquito thanks to the excellent work carried out on site. Trélex and Prilly have also been successfully treated in previous years, which confirms the usefulness and effectiveness of preventive measures.

Traps to attract females

This year, monitoring is taking place in the municipalities of Nyon, Préverenges, Bussigny, Crissier, Lausanne, Cully, Vevey, Aigle, Bex and Yverdon. In total, 69 nesting traps have been distributed in places likely to attract possible females ready to lay eggs and will be recorded every two weeks.

Municipal employees benefit from training and support during the season. In the event of a positive reading, treatment is carried out immediately by the authorities using a targeted action biocide, without impact on the rest of the environment, and surveillance is increased. It has already been carried out at the end of April in Nyon, Préverenges, Crissier and Lausanne.

The public is invited to collaborate by eliminating all places favorable to egg laying, that is to say small collections of inert water (water bowls, old tires, holes in the walls, abandoned uncovered containers, watering cans , etc.) and to report any mosquitoes active during the day on the national platform www.moustiques-suisse.ch.
