Climate change means that the stinging caterpillars can now be found almost everywhere in France, after being confined to certain areas in the south of the country.
The warm spell in May prompted an increase in sightings of chenilles processionnaires (processionary caterpillars) in almost all areas of France.
One ‘exceptional outbreak’ in particular, in Yvelines, near Paris, prompted the préfecture to close sections in the north and west of the popular forêt de Rambouillet to the public for more than two weeks.
To the delight of joggers, hikers, and families, the forest trails are due to reopen on Saturday, June 13th – but officials have urged anyone visiting the forest to remain cautious: “Vigilance is still essential, as processionary caterpillars and their stinging hairs are still present,” the préfecture said in a statement announcing the forest’s reopening.
It recommends wearing protective clothing, avoiding contact with caterpillars, their nests, or trees on which their nests can be seen, and keeping children and pets under close supervision. It also advised visitors to wash their hands upon returning home.
