With the falling leaves and return of rain after a dry summer, Asian hornet (vespa velutina) nests are becoming more visible in Bourgogne-Franche-Comté. Although 2026 appears less favorable for their development, the species continues to expand in the region. These nests, often hidden in foliage since July or August, gradually become visible as trees lose their leaves, sometimes several meters high, explains Robin Jacoutot, environment manager at FREDON Bourgogne Franche-Comté.
