Oak procession spinner
The Oak Procession Spinner is a brown-grey butterfly that flies from the end of July to the beginning of September and is harmless to humans. However, the butterfly's caterpillars, which are considered to be pests, pose a significant danger to humans. They hatch at the beginning of May, mainly infest individual trees (mainly oaks) and feed on its foliage. Until the pupation at the end of June/beginning of July, they go through up to six stages of development. In mid-June, the older caterpillars retreat during the day and for skinning in spun nests. From there, they go in search of food. Dangerous for humans are above all the burning hairs of the caterpillars with their characteristic nettle poison and the barbs. These can cause itchy, inflammatory rashes, redness, quads and blisters (raupenderdermatitis), rashes or even allergic shocks. Fully formed caterpillars have around half a million firing hairs, which break easily and are thus carried through the air by the wind. As a preventive measure, you should avoid direct proximity or direct contact with the caterpillar and its nests. From the spider-nests, in which the burning hairs remain, there is still a danger for years to come. Contact avoidance as an elementary protective measure also applies to pets such as dogs or free-running cats. If you notice an infestation in your garden, you should have the control done by professionals (pest controllers or tree keepers) as the burning hairs can be easily whirled up and there is an increased risk of injury to you and your environment. It is therefore not recommended that we combat it yourself. There is no obligation to notify the oak procession spinner for private individuals, but the notification is recommended.
The notification of the oak procession spinner in public spaces is free of charge. The costs of combating the oak prozzestion spinner on private land are borne by the owner himself.
