Notices have been put up at some entrances to Gobions Wood reserve warning people to keep away from a certain caterpillar that, if touched, can cause “unpleasant skin, eye and throat irritations”.
A sign, produced by the Forestry Commission England and Herts and Middlesex Wildlife Trust (HMWT) asks for the public’s help in controlling what is described as a pest.
According to the sign, “caterpillars of the oak processionary moth could be damaging oak trees in the area”.

The public is asked to contact HMWT if they see processions or clusters of the caterpillars in oak trees; or silken webbing trails or nests on the trunks or branches of oak trees.

Visitors to Gobions Wood should keep away from the caterpillars and nests and are asked to call NHS 111 or see a doctor if they develop serious allergic reactions.
In April, North Mymms Parish Council (NMPC) cordoned off an area of a public park off Dellsome Lane, Welham Green after the discovery of the oak processionary moth caterpillar.
