Germany on alert as Asian tiger mosquito population surges
Experts from Germany are appealing to residents for help in combating the Asian tiger mosquito, which appeared en masse in the region in 2024. "In 2025, there will be more bloodsuckers than ever before," warns "Bild".
In 2024, weather conditions favoured the spread of the Asian tiger mosquito in Germany. Experts from the "Municipal Action Group for Combating the Mosquito Plague" (Kabs) emphasise that residents' involvement is crucial.
Over 80 per cent of breeding sites are located on private properties - informs Kabs.
In 2025, the launch of an information campaign is planned to educate residents about the proper handling of this invasive species. Kabs is preparing for this by refreshing its website and promotional activities.
The Asian tiger mosquito, measuring only a quarter of an inch, poses a significant challenge for experts. After the floodwaters receded, its mass occurrence was recorded in 38 new municipalities in southwestern Germany. In total, in 2024, these mosquitoes appeared in 47 out of 89 municipalities associated with Kabs.
Germany. Increase in mosquito population
The increase in the number of tiger mosquitoes in 2024 was the result of frequent rainfall and favourable conditions for reproduction.
A lot of rain, a lot of mosquitoes - summarises Kabs.
Despite successes in combating native species, the Asian tiger mosquito has proven more challenging to control.
In 2025, the problem with tiger mosquitoes may intensify if the trend of hot summers continues.
If summers remain hot, the number of tiger mosquitoes will grow - says Xenia Augsten from Kabs, quoted by "Bild".
Floods also favour their spread.
Regulating the mosquito population is important, as residents of the Oberrheingraben region felt in 2024. After the May and June floods, there was a mass appearance of aggressive woodland mosquitoes.
High numbers of mosquitoes were reported from all over Germany, as a result of humid conditions in spring and summer.
