Experts have warned that toxic caterpillars capable of triggering asthma attacks, vomiting, and skin rashes are expanding their range beyond London. The oak processionary moth caterpillars, currently in their larval stage, have been sighted across the south-east of England.
Officials are attempting to control the spread of these pests, but acknowledge that they will likely continue to move 'further and further' across the region. The caterpillars are known for their distinctive habit of moving in nose-to-tail processions, from which they derive their name.
The hairs of the caterpillars contain a toxin that can cause severe allergic reactions in humans and animals. Contact with the hairs can lead to skin rashes, eye irritation, and respiratory problems, including asthma attacks. In some cases, vomiting and other symptoms have been reported.
Authorities advise the public to avoid contact with the caterpillars and their nests, which are typically found on oak trees. Pest control teams are working to remove the nests and reduce the population, but the spread of the species is proving challenging to contain.
