Residents in Pyrford are being encouraged to stay vigilant for signs of oak processionary moth (OPM), a pest that can affect oak trees and pose health risks to people and pets. The caterpillars are now established across parts of Surrey and are most commonly seen between late spring and summer.
Oak processionary moth caterpillars are easy to recognise by the way they move in nose-to-tail processions along oak trees. They also build distinctive white, silk-like nests on trunks and branches. Their tiny hairs can cause skin irritation, rashes, sore throats and breathing difficulties, so nests and caterpillars should never be touched.
Importantly, the presence of oak processionary moth does not mean an oak tree needs to be removed. In most cases, specialist treatment and careful management can successfully control the infestation while allowing the tree to remain healthy and protected.
If you spot suspected oak processionary moth caterpillars or nests in Pyrford, avoid the area and report the sighting through the official Tree Alert service operated by Forest Research. Prompt reporting helps experts monitor and manage the spread of this invasive pest, protecting both local oak trees and public health.
