Oak Processionary Moth

The oak processionary moth is native to central and southern Europe and breeds in oak trees. Since 2006 larvae (caterpillars) of the oak processionary moth have been found at several locations in London. This species feed on the leaves of the oak and produce nests of silken thread on the trunk or branches of affected trees.

Larvae of the oak processionary moth are also a risk to human and animal health. The hairs from larvae or nests contain a toxin that can result in severe skin irritation, eye problems and allergic reactions.

If you think you have been exposed and are suffering symptoms contact your GP or |NHS Direct.

Important Facts

• Don't touch the caterpillars or their nests.
• Don't try to deal with an infestation yourself. It needs specialist treatment and contact with the caterpillars or nests could endanger health.
• Keep children and pets away.
