Oak processionary moth

It is important not to come into contact with oak processionary moth caterpillars, hairs or nests as their tiny hairs can cause skin rashes and less frequently eye and throat irritations and breathing difficulties in people and animals. Pets must be kept away from the nests and caterpillars.

If you do come into contact with the larvae or caterpillars by accident, please follow the health advice about dealing with caterpillar hairs on the NHS website. If you have an itching skin rash and/or conjunctivitis or other symptoms, contact your GP, or call NHS Direct on 111.

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