Oak Processionary Moth

Oak Processionary Moth is a notifiable pest which the City of London are working closely with the Forestry Commission to control. The species' caterpillars shed allergenic hairs which can cause a serious rash in both humans and animals on contact. The caterpillars cause minimal damage to the trees themselves unless the caterpillar numbers are very high. The pesticide is a naturally occurring bacterial extract that targets only caterpillars feeding at the time of application and poses no risk to people, animals and other wildlife.

For further information on OPM visit our dedicate page on Oak Processionary Moth. If you have any questions or concerns please call 0207 332 3322.

It is important for the public, and their pets, not to touch or approach any nests or caterpillars and, if found, to alert Heath staff on 020 7332 3322, and to then alert the Forestry Commission.
