Processionary Caterpillar Alert in Rennes Metropole

The Regional Health Agency of Brittany (ARS) has issued an alert regarding the presence of oak processionary caterpillars in specific areas of two communes within Rennes Metropole. The agency urges residents to report sightings of these irritating caterpillars through a dedicated reporting platform. The infestation has prompted ongoing phytosanitary treatments, though the risk of exposure remains significant, as the caterpillars retain their urticant properties even after death.

In Rennes, the affected areas include the streets of Chateaugiron and Vezin, as well as the Louise-Bodin daycare and the Charles-Géniaux square. In Saint-Jacques-de-la-Lande, specific avenues are under scrutiny. The ARS emphasizes that direct contact with the caterpillars or their nests can lead to severe health risks for both humans and pets.

What to Expect Next

Local authorities may expand their monitoring efforts if new infestations are reported. The ARS could also increase public awareness campaigns to educate residents on identifying and avoiding the caterpillars. However, no further details on additional measures have been announced at this time.
