Oak Processionary Moth

The oak processionary moth is a pest that has been found in parts of Surrey in 2017-18. They live in oak trees and pose a risk to human and animal health, as well as to the trees themselves.

It is important not to come into contact with oak processionary moth caterpillars, hairs or nests as their tiny hairs can cause skin rashes, eye and throat irritations and breathing difficulties in people and animals who come into contact with them.

May to July is the greatest risk period when the caterpillars are most numerous.
