Saxony-Anhalt threatens Eichen processionary spinners: Communities act now!

Dessau-Roßlau, Deutschland - The dangers of the oak processionary spinner - a growing problem

This year the oak processionary spinner has further strengthened its spread in Germany. Cities in the north and east of Saxony-Anhalt in particular report serious problems, despite all efforts with chemical and biological measures to contain insect. According to [Radiosaw] (https://www.radiosaw.de/artikel/Sachsen-Anhalt-icheiche-processessionSpinner-Sich-Aus), climate change, in particular the dry and warm spring, is one of the main reasons for the mass use of this heat-loving butterfly species.

In the special case of the oak processionary mint, caterpillars are the actual culprits. These little guys not only cause optical problems in forests and gardens, but can also cause allergic reactions in humans. Numerous cases of skin irritation and shortness of breath have been observed, favored by the burning hair of the caterpillars, which are formed from the third larval stage. The [Federal Environment Agency] (https://www.umweltbundeamt.de/eichenpronverwinner-wert- on-haeuft) informs that the caterpillars themselves have a nettle poison that can even lead to fever in contact with symptoms such as reddening of the skin, itching and in some cases.

control measures in the communities

The communities react differently to the threat. Some cities have already started to vacuum the caterpillar nests, whereby one focuses primarily on residential areas, kindergartens and sports fields. However, the complete removal of all nests is almost impossible, especially in forests and nature reserves, where no chemical control measures may be carried out, except for special permits. These restrictive measures are necessary for the protection of the organisms living there and the tree vegetation, as lwf Bayern.

On the banks of the Muldestaire, the community has considered a particularly creative solution: a nesting box offensive. The promotion of natural predators such as titmons and bats hopes to counteract the oak processionary spinner. Existing boxes from school projects contribute to supporting these natural enemies.

proven control methods

How can you successfully combat the oak processionary spinner without resorting to chemical means? According to the Federal Environment Agency, insecticides should be avoided in the event of weak infestation and low human use. Instead, it is recommended to set up warning signs and lock affected areas. In many cases, professional pest control can help to absorb caterpillars or nests.

biological control measures are considered more environmentally friendly and selective. Products with Bacillus Thuringiensis are among the recommended means, while chemical methods should only be used in exceptional cases - and then only under strict conditions so as not to endanger the environment.
