On Tuesday 1 September 2026, Luxembourg’s Ministry of Health and Social Security announced the launch of an awareness campaign for the residents of Luxembourg-Bonnevoie following the discovery of Tiger mosquitos in the area.
According to the ministry, regular and routine monitoring carried out by the Health Inspectorate of the Health Directorate over the past few years has recently confirmed the presence of the Tiger mosquito (Aedes albopictus) in the capital city’s Bonnevoie district. Diseases transmitted by these mosquitoes are increasing in Europe, in regions that are increasingly close to Luxembourg. Cases of locally acquired dengue and chikungunya are reported in France every summer.
Several reports of Tiger mosquitoes had already been recorded in Bonnevoie since 2023. Their recurrence suggests that the Tiger mosquito is now established locally in this area. In order to inform residents about the measures they can take to limit the spread of this mosquito, the Health Inspectorate Division of the Health Directorate is organising a door-to-door awareness campaign on Wednesday 2 September, between 16:00 and 20:00 in the area where mosquitoes have been detected around the Kaltreispark district in Luxembourg-Bonnevoie.
Enhanced monitoring from mid-April to mid-November
The ministry has detailed that traps for collecting eggs or adult mosquitoes are installed by Health Directorate staff at various locations across the country from mid-April to mid-November. The specimens detected are then identified in collaboration with the Luxembourg Institute of Science and Technology (LIST).
The ministry emphasised that observations submitted by the public help to complement this system. With the free Mosquito Alert app, anyone can photograph and report a suspected mosquito. These reports enable the authorities to monitor its presence more effectively and adapt surveillance accordingly.
Preventive measures
The Tiger mosquito mainly lays its eggs in stagnant water around homes, even in small quantities. To slow its reproduction, it is recommended that containers and small bodies of water be emptied and cleaned at least once a week. Rainwater collectors must be covered, while gutters and drains must remain clear. Objects that could collect rainwater should also be stored under cover. In addition, individual precautions can be taken, such as using mosquito nets over beds or on windows.
