Updated on 06/09/2016

Processionary caterpillars are insects that are found in many regions of France, including urban areas. They compromise the health of trees, and also have an impact on human health as their bristles can cause inflammatory skin reactions, as well as more serious allergic reactions of the respiratory mucosa. ANSES, asked to assess alternatives to chemical treatment for the control of these insects, recommends a combination of preventive and curative measures.
