The Forestry Commission has today urged the public to report sightings of oak processionary moth caterpillars. We are now entering the greatest risk period as the caterpillars emerge between May and July to feed before turning into adult moths.
Oak processionary moth, which is a tree pest, was first identified in London in 2006 and has since spread to some surrounding counties in the South East of England. Its caterpillars and their nests contain hairs which can cause itchy rashes, eye and throat irritations, and should not be touched under any circumstances.
Oak processionary moth caterpillars also feed on the leaves of several species of oak trees. This can cause the trees to lose their leaves, negatively impacting their growth, and become more vulnerable to other stresses, like drought.
Andrew Hoppit, Oak Processionary Moth Project Manager, said:
At this time of year, many of us enjoy being outdoors in green spaces of all kinds. If you live in London and the surrounding areas, it's really important for you to be aware of the health risks posed by tree pests like oak processionary moth.
Any sightings should be reported to the Forestry Commission via our TreeAlert portal. Alternatively, you can email opm
