Asian hornet most active at this time of year: what to do in case of a sting or if you find a nest?

The Asian hornet (Vespa velutina) is now present throughout Portugal, with over 5,000 nests destroyed by the end of July this year. The species reaches peak activity in late summer and early autumn, when nests are at their largest. If stung, wash the area with soap and water and apply a cold compress; if you experience breathing difficulties, facial swelling, or dizziness, seek medical attention immediately via 112. Report any sightings of nests or individuals to help authorities track the species.
