Residents in Surrey are being warned after oak processionary moths (whose caterpillars can cause health problems) are reported in several local areas. Multiple outlets report sightings around Woking, Weston Green, and Ditton Common, urging people to stay vigilant during the summer period. The warnings highlight that the caterpillars’ hairs can irritate skin and affect people and animals, and that exposure may be harmful if contact is made. Some coverage links the renewed sightings to warmer conditions, referencing a recent heatwave, although the reports focus primarily on local detections and public awareness rather than on new scientific findings. The advice given to residents centers on taking care around affected trees and not touching caterpillars or any webs they leave on vegetation. The reports describe this as a recurrence after previous years in which the species caused concern, with local communities again asked to monitor gardens and woodland edges for signs of infestation and to follow any guidance from local authorities.
