Eichen processionary spinner: XXL infestation in MV ensures great worries!

Ludwigslust-Parchim, Deutschland - The spread of the oak processionary spinner in Mecklenburg-Western Pomerania has reached unprecedented dimensions this year. In the region, the number of nests per tree and the spread of the dreaded butterfly caterpillar are at a level that has never been documented before. The district of Ludwigslust-Parchim is particularly affected, where those responsible had to react to the rapid increase with control measures. In 2023, insecticides were even intervened here by helicopter.

The situation is alarming for experts. "It is too late for this year," it says, "since the caterpillars have already been transferred to the doll phase." Nevertheless, it is expected that another fight will be necessary in the coming year. The appearance of the caterpillars in endangered places such as bathing areas and kindergartens has also tightened the situation.

health dangers through contact

The small but dangerous hairs of the caterpillars are known for their health risks. Contact can lead to allergic skin reactions, eye infections and respiratory problems. The skin in particular is affected: uncovered areas such as neck, face, arms and legs can itchy and painfully swell. The technical term for the symptoms is caterpillar matitis, and the reactions are diverse: from squaddling to reddening of the skin to vulnerable areas that can ignite. In severe cases, anaphylactic shocks can even occur that require quick action.

"If you come into contact with the hen hair, you should immediately change your clothes, clean your skin thoroughly, shower and rinse your eyes," advises an expert. The eye area reacts particularly sensitively, where acute conjunctivitis can result. Inhalation the hair also often leads to cough and can even trigger shortness of breath in preloaded people.

causes and spread

One of the main causes for the sudden increase in caterpillar numbers lies in climate change, which favored the increased occurrence of oak processionary spinners. In recent years, the caterpillar population has increased not only in Germany, but also in other parts of Europe. The distribution usually takes place from the southwest towards the northwest, which also affects neighboring counties. The previous data from Brandenburg also show high suffering from the affected residents.

preventive measures are essential. Avoiding the affected areas and ensuring appropriate protective measures. Nests on oaks not only have to be removed, but this often happens under expensive and elaborate protection precautions. Areas with recognizable damage - bare branches and webs - should be kept in mind.

residents and authorities will have to deal with these challenges in the coming months to counter the dangers of the oak processionary spinner.
