Oak Processionary Moth was first identified in this country on imported trees planted at a housing development in Kew in 2006, after residents reported unexplained rashes and breathing problems.

Since then extensive measures have been taken to try to restrict their spread – see the Forestry Commission’s website.

Left uncontrolled, the species could spread across much of Britain, weakening oak trees by repeated defoliation, and presenting a risk to human and animal health. The caterpillars have tiny hairs which can cause the skin rashes, eye and throat irritations and breathing difficulties seen in Kew during the initial outbreak.

Do not attempt to deal with nests yourself. If you see nests or caterpillars in public parks, open spaces, communal gardens, or on golf courses, please report them:
