Professionals involved in nest destruction unanimously report that in autumn 2026, Asian hornets formed fewer colonies than in 2025, but those that survived became enormous. October is a key month for observing these insects; nests, often unseen since July, suddenly appear at the end of branches, sometimes over fifteen meters high. According to the National Museum of Natural History, the usual cycle starts in April with a single founding queen, a nest the size of an orange, followed by rapid growth until autumn. In 2026, however, the volume of nests seen in October is exceptionally large.
