Flemish Region Steps Up Fight Against Asian Tiger Mosquito
Public health officials intensify efforts as this invasive species, known to transmit diseases like dengue and Zika, becomes increasingly common in Belgium due to climate change
The Flemish Region has intensified its campaign against the Asian tiger mosquito, an invasive species that can spread diseases such as dengue and Zika. As global warming leads to milder winters, these mosquitoes are being reported more frequently across Belgium, raising concerns among public health officials. Since 2021, local nature and health agencies have collaborated to track the spread of the species throughout the region.
Reports suggest the mosquito now has a foothold in 21 Flemish municipalities, with most sightings near highways, pointing to spread through passenger and cargo transport. In the last year alone, monitoring confirmed the mosquito was overwintering in five areas, a sign of growing adaptation. To help control the population, officials have urged citizens to report sightings through a dedicated online platform, and have launched inspection and prevention measures in gardens and homes.
The authorities have prioritized preventive actions such as adding larvicides to rain barrels, which provide ideal breeding grounds, and conducting checks in households across targeted areas. In May, a new awareness campaign was launched to inform residents about the public health risks and precautions they should take. Officials emphasize that eliminating potential breeding sites is crucial to slowing the mosquito’s spread, and encourage everyone in the region to take part in the efforts.
