Processionary caterpillar nests on pine trees in a public park in Mèze, Occitanie, at dusk.

The City of Mèze continues its nocturnal treatment operation against pine processionary caterpillars in public spaces this Tuesday, October 13.

The City of Mèze has resumed its nocturnal treatment operation against pine processionary caterpillars. This intervention, carried out by a specialized company, involves spraying a biological insecticide on pine trees located in the public areas of the municipality.
This method aims to protect the trees while safeguarding the health of residents, domestic animals, and the natural balance. Teams will be working at night, particularly this Tuesday, October 13, to treat the affected pine trees.
This control campaign is essential to limit the proliferation of caterpillars before they emerge from their cocoons. The urticating hairs of these caterpillars can indeed cause severe allergic reactions in humans and serious lesions in animals.
