Oak Processionary Moth Caterpillars

Caterpillars of the oak processionary moth could be damaging oak trees in this area

Their hairs can cause unpleasant skin, eye and throat irritations in people and animals.

You can help the Forrestry Commission control this pest so we can all continue to safely enjoy our parks and woodlands.

Please tell the Forrestry Commission if you see:

  • processions or clusters of caterpillars in oak trees; or
  • silken webbing trails or nests on the trunks or branches of oak trees

Remember to:

  • keep away from the caterpillars and nests
  • call NHS111 or see a doctor or vet for serious allergic reactions

Nests or caterpillars in other trees are unlikely to be OPM and do not need to be reported.

Report OPM with Tree Alert at forestry.gov.uk/opm or opm@forestry.gsi.gov.uk or 0300 067 4442
