LOŠ KREUZNACH – In the city district of Bad Kreuznach, but also in the built urban area, many oaks are re-attacked by oak rolls of procession molasses. As the city noise warns, there is a great danger to health when people come into contact with caterpillars. Pests prefer oaks at the edges of the forest, in green areas, in parks, in sports fields and pools, or where many people often find themselves in the vicinity of trees.
As the name suggests, the heavily hairy, about four to five centimeters long oak procession in the long cord ("processions"), sometimes in broad strips along the trunk, walks to their feeding places in the crowns. There they eat from freshly squeezed leaves from top to bottom, leaving behind the middle of the leaves.
The oak procession moth was originally found in the Middle East, southern Russia and southern Europe. In Germany there are about 200 years. Since 2005, he has frequently appeared in Rhineland-Palatinate. Because of climate change here in the country, spring and summer become warmer. Processed oak trusses tend to proliferate especially in dry years and almost exclusively come from oak and oak tree as well as American red oak.
Between the long-sighted hairs, the caterpillars still have micro-hairs that can be removed when they are anxious animals or even actively "felled" by caterpillars. Dangerous micro-hair is also accumulated in large quantities in so-called " The networks where the caterpillars skin, and later the bark. Fine filament sacks are often found on thickets and branches of falling oaks, three to five meters, but also on the ground.
Symptoms: skin irritation, allergies, asthma
If fine hairs hit the skin, the protein in it is empty. Sensitive people can feel irritation such as itching, allergic reactions, asthma symptoms or even shock symptoms. Especially the thin skin on the neck, the area of the neck, the inside of the arms and the armpits are particularly affected. Inhaling fine hair may irritate the respiratory tract and cause respiratory distress. Patients with persistent and severe side effects should consult a doctor.
It is partially confused with other hairy cans. So in some cases it may have been clear because it was a sponge bolt, Spring Wollafter or sometimes milk. "Markant," oak wood processors say, "are the black head, the dark backline and the long, light-haired caterpillar and the appearance of caterpillars on the hoe or in the branches of oak groves."
Therefore, people should avoid contact with trackers in any case. This also applies to nests that can hang on oaks until autumn or even winter. Forest visitors need to remain on the trail, while adult women gather in dry weather on the ground. In addition, walkers should pay special attention to the signs and barriers in forest parks, grilling areas or playgrounds, and avoid the self-inflating of indigenous wood trees.
The City Forest explicitly warns the caterpillars and their networks by hand, for example, in home gardens for battle. They must be removed by a special vacuum cleaner by a specialist in the protective equipment and properly disposed of.
"We are delighted to be able to provide advice and, where possible, active support for investigations of this kind," says Forest Forester Michael Veeck from the Soonwald Forestry Office. "Pest control experts require the removal of special sources of dangers on private property, because they are pests of insects. We are happy to convey these contacts," says Veeck.
