Danger from oak processionary spinners: warnings for Reinickendorf!

In the parks and green areas of the Reinickendorf district, we are currently increasingly observing sprints, which mainly come from climbing moths. This type of butterfly belongs to the moth family and has enjoyed increasing distribution in recent years. Julia Schrod-Thiel, the district councilor for order, environment and traffic, emphasizes that these moth-like creatures do not run any danger. In contrast, the caterpillars of the oak processionary spinner, which have increased in recent years, have potentially health -hazardous properties.

The clock moths lay their eggs on the branches of shrubs and trees in July and August. The slippery caterpillars hibernate and start eating on the young shoots from April. From the beginning of May, the caterpillars can be seen when they spin striking, white nets around wooden parts or smaller plants. Although the affected plants can be weakened by the leaf feeding, they usually recover well after the infestation period, so [berlin.de] (https://www.berlin.de/ba-reinickendorf/aktuelles/pressemaytreungen/2025/Pressemage Department.

The district office reports that you have received more information on the oak processionary spinner. For this purpose, warning signs on the part of the road and in parks were set up to inform citizens about the potential danger. Citizens are urgently asked to avoid infested oaks and not touch caterpillars or nests in order to avoid health risks. The caterpillars of the clamping moths are also not dangerous, but the dense brockers in the trees can have a worrying effect.

causes of the distribution

The increase in the spinning moths is favored by mild winter and a dry, warm spring. In Central Europe there are over 70 types of web moths, each specializing in certain feed plants. The most common include the apple groove moth and the plum pins, each affecting specific tree species (e.g. apple and cherry trees). In contrast, the caterpillars of the oak procession spinner can mainly be found on oaks and can occur in large groups, which also leads to increased concerns in the population, such as mdr.de. In summary, it can be said that the citizens concerned should be careful in the interest of their own health and health of the plants in their environment in order to escape the potential dangers that can be used by both web moths and oak processionary spinners.
