The larvae of this moth species have been spreading in Luxembourg for several years. They not only damage trees, particularly oaks, but also pose a health risk to humans. While the caterpillars have long existed in Luxembourg – mainly in forests – they have increasingly begun to invade urban areas in recent years.
As the name suggests, the oak processionary moth primarily targets oak trees and can cause serious health problems for both humans and animals. The toxic hairs on the caterpillars can lead to allergic reactions, including intense itching, skin inflammation, and irritation of the eyes and respiratory system.
Anyone who comes into contact with the stinging hairs should wash the affected skin immediately, and also wash any clothing that may have been exposed. In the case of more severe symptoms, it is strongly advised to consult a doctor.
The Ministry of the Environment published an information leaflet in German with prevention guidelines as early as 2017.
