Droves of white-haired caterpillars have invaded the British capital, with experts warning they can trigger allergic reactions in humans and pets.


The BBC reports that UK officials have issued a health warning following an outbreak of toxic caterpillars of the oak processionary moth across London and southeast England.


The species is a native of Southern Europe, but was accidentally introduced to Britain via imported live oaks in 2005.


Each caterpillar contains 62,000 hairs, which are full of spines that can prick skin. They can be released from the body and stay active for up to five years.


The hairs contain an irritating substance called thaumetopoein that can cause skin rashes, eye irritation, sore throats, and breathing difficulties.


The British Forestry Commission has begun using biopesticides to help eliminate the caterpillars, and have cautioned residents against letting children or pets near affected areas.


Traps will also be set for the invasive insects around the 150 hotspots identified by the commission.
