Report oak processionary moth infestation
The poisonous hairs of the oak processionary caterpillars can lead to allergic reactions. We can advise you in the event of a tree infestation in the urban area.
Course description
The oak processionary moth is a butterfly. Its caterpillars prefer to infest oak trees and have hairs containing the nettle toxin thaumetopoein. In humans, this can cause allergic reactions to the skin, eyes and airways as well as bronchitis, asthma and allergic shock reactions. From June, the caterpillars pupate in webs. Old larval skins remain in the nests after moulting and therefore pose a long-term risk to human health.
Anyone who sees oak processionary moth infestations in the Munich city area can report this to the health department. We will be happy to advise you.
Important note
If you experience breathing difficulties after inhaling fine hairs or following contact, call the emergency services on 112 immediately.
