Any person sitting outdoor on a summer season night within the Higher Rhine area lately has no concept that this was once hardly imaginable a couple of a long time in the past. The explanation: hordes of mosquitoes. The affiliation for the combat towards the plague of mosquitoes and gnats was once based as early as 1910. However good fortune remained modest. After the 2nd Global Struggle, the struggle construction collapsed. An overstatement: you needed to reside with the pests – or keep within.

In 2026, it’s going to be 50 years because the municipalities of Rhineland-Palatinate, Hesse and Baden-Württemberg sought after to forestall. It was once the founding hour of the Municipal Motion Staff to Struggle the Plague of Mosquitoes, or Cubs for brief. The speculation was once so simple as it was once formidable: to keep watch over mosquitoes with out destroying nature. It’s odd that this purpose has infrequently modified in part a century. “Everything else has fundamentally changed,” says Cubs clinical director Dirk Reichle.
“At first, experts experimented with the carbamate Fenethcarb and the paraffin oil mixture Liparol,” says Reichle. “However, the real revolution came – almost to order – in the year the club was founded. In the Negev desert, Israeli scientist Joel Margalit discovered a bacterium whose protein crystals specifically kill mosquito larvae: Bacillus thuringiensis israelensis, or Bti for short. “Cubs examined the lively aspect at the box as early as 1980, and because 1983 it has grow to be the usual – till lately.
As the process changed into extra subtle, the placement changed into extra sophisticated. 5 unique species have now unfold within the Higher Rhine area: along with the Asian tiger mosquito, the Jap and Korean mosquitoes, in addition to Culiseta longiareolata and Anopheles petragnani. “With the Asian tiger mosquito, health care comes to the fore,” says the Cubs director. Since 2025 at the most recent, when a case of native transmission of chikungunya fever was once first recorded in Alsace, it’s transparent: “The area has grow to be extra inclined.
An exemplary instance of municipal cooperation
And but: the stability sheet of Cubs is thought of as an exemplary instance of municipal cooperation. In alluvial forests and wetlands, the related species are so strictly regulated that complete spaces of land have won new freedom. “The idea of being able to stay outdoors undisturbed after a flood would have been grotesque before 1976,” says Reichle.
The Ministry of Atmosphere, Power, Meals and Forestry of Rhineland-Palatinate has described the paintings of Cubs as “indispensable” as early as 2021. The result’s “increased life and quality of life for citizens in the affected areas,” in line with the reaction to a small question.
The unfold of the Asian tiger mosquito
Then again, the Cubs aren’t working utterly easily. For the reason that amended law (ChemBiozidDV) got here into pressure, municipalities are allowed to factor Bti pills best after particular coaching. Any person who completes it has 5 years of peace – however the coaching program results in Might 2026. It’s unclear whether or not the law shall be prolonged, amended or scrapped altogether. Taking into consideration the unfold of tiger mosquitoes, the Cubs are on the lookout for a call from Berlin.
The affiliation is financed thru contributions from member municipalities, dispensed in line with the selection of population. There also are third-party finances from tasks reminiscent of Interreg. The price range has grown considerably over the a long time and now quantities to round 7.8 million euros. 71 staff paintings for Kabove at all times, and relying at the season, as much as 200 further staff are assigned.
It best works in combination
50 years after it was once based, the Cubs have lengthy been regarded as a good fortune. The ones accountable level to an element that doesn’t seem in any organic research: harmony. “Almost all the inhabitants of the Rhine region join,” emphasizes Reichle. “This is the only way to fight something that effortlessly flies across municipal borders. The place itself would have neither the financial resources nor the chance to succeed.”
After which there may be the parable that persists, the director says: that the Cubs are spraying Bti over huge spaces in coastal forests. Actually, the membership has been the use of a finely balanced mapping gadget for many years. Simplest identified breeding websites could be handled – in a patchwork type, no longer of their entirety. This may be a lesson from 50 years of mosquito keep watch over: precision trumps breadth.
