Oak processionary moth

This non-native moth is damaging oak trees in the UK

THE oak processionary moth poses not only a risk to oak trees across the UK, but to human health, too. Caterpillars of the oak processionary moth feed on the leaves of oak trees. This causes serious leaf loss and weakens the tree. The oak tree is then more vulnerable to other threats.

The caterpillar has tiny hairs which can be blown

by the wind and can cause skin rashes, eye and throat irritations and, occasionally, breathing difficulties in people and animals.

This pest is predominantly found in areas around London. However, it is spreading and expected to reach most parts of the UK at some point in the future.

HOW YOU CAN HELP:

Tree diseases and pests like oak processionary moth illustrate the need to increase woodland creation and plant a diverse mix of native species. Planting in this way will help mitigate the impact of pests and diseases, by offering alternative habitats. If you suspect that your tree contains an oak processionary moth nest do not disturb it. It should be reported to the Forestry Commission via Tree Alert: visit forestry.gov.uk/treealert.

The Woodland Trust can offer you financial support and advice for your planting. This includes subsidised trees, guards and stakes and one-to-one advice and support from our woodland creation advisers.
