Karlsruhe fights against ant invasion: Lasius Neglectus spreads!

The city of Karlsruhe is currently facing a real plague of ant, which is increasingly concerned with the residents in the districts such as Knielingen. The invasive Art Lasius Neglectus, also known as the "forgotten path ants", ensures massive problems among the citizens who complain about the crawling animal invasion on terraces, streets and garbage gears. The local government does not remain idle: the city is in constant exchange with experts in order to take suitable measures and to contain the spread of the ants. As [ka-news.de] (https://www.ka-news.de/region/karlsruhe/invasion-der-e- also Karlsruhe-kaempf-men-krabbelten-Art-3341818), residents have been struggling with the pests for years.

The situation continues to come to a head because the colonies of the path ants apparently grow. Originally from the Black Sea area, Lasius Neglectus has been detected in Germany since the late 1990s and has now gained a foothold in around 15 municipalities. The first proof was made in the botanical garden in Jena. The ant species is also active in the southwest, for example in Ludwigsburg since 2017 and in Bad Säckingen and Wehr, where it also causes problems. The topic was particularly concise by the incident with the Kehler ant, Tapinoma Magnum, which led to power failures and internet interruptions in 2024. In Kehl a playground was even closed because of the high number of ants.

A common procedure is required

For combating the path ants, a similar effort seems to be necessary as with Tapinoma Magnum. According to the ants researcher Manfred Verhaly, a combination of ants bait and hot water is recommended to master the plague. "The path ants is less snappy and frost -sensitive than their relatives. That makes them a bit more harmless, but fighting is no less challenging," explains Verhaly. Special hot water devices are used in Kehl to combat pork colored. But the procedure requires a high level of personnel.

An important element in combating is the interaction between public bodies and private property owners. The existing colonies can only be fought sustainably through a common procedure and the spread can be contained. The city of Karlsruhe is to develop strategies in order to better take into account the circumstances and to cope with the invasion, and is in close contact with other affected municipalities. In view of the current situation, it remains to be seen which measures will actually apply.

research projects for spreading

In a ray of hope for the affected districts, a joint research project of the Natural History Museums Stuttgart and Karlsruhe, which is devoted to the dynamic spread of the ants. In this project, the colonies should be examined more closely in order to learn more about their distribution and to make predictions about new settlement areas. This project could provide important insights to better counter the constant threat of invasive species such as Lasius Neglectus and Tapinoma Magnum, as well as all-in.de reported.

The commitment of science and city administration shows that one wants to face the challenge by these unpopular roommates. It is to be hoped that the measures will soon have an effect and that the residents in Karlsruhe can enjoy peace again before the crawling animals. Further information is published on the project's website, where interested parties can keep up to date with the progress of the efforts.

The announcement of the unwanted intruders could serve as a wake -up call for many citizens who have not yet dealt with the topic. Nature is always in change and adaptable - the question remains, how we deal with it and position ourselves as a society when it comes to the balance between urbanity and nature.

Current trends in ant research and the long -term effects of invasive species throw a new light on biodiversity in Germany. While we get used to a new normality, we also have to be ready to take the necessary steps to protect our environment.
