Oak Processionary Moth Information


Clusters of OPM caterpillars are active in late-Spring. If you come across the caterpillars or their webbed nests please do not touch them and keep children and pets away.

The hairs of the caterpillars carry a toxin which can be a threat to human health, causing skin rashes, eye irritation and respiratory problems.
