The presence of the Asian hornet, known as Vespa velutina, has recently been confirmed in the Algarve, prompting a public alert from the municipal council of Portimão.
“At this time of year, small primary nests are commonly seen,” the council says in a small statement posted on social media.
It adds that these nests are usually found in sheltered spots such as roof eaves, outbuildings, bushes or similar structures. They are typically small and rounded, often described as pear-shaped or about the size of a tennis ball.
Local officials are asking residents to stay alert and report any suspected nests, but not to approach them.
“If you identify a nest with these characteristics, do not approach it or attempt to remove it,” the notice states.
Instead, Portimão-based sightings should be reported to the Municipal Civil Protection Service via the Proteção 24 hotline at 808 282 112, where the situation will be assessed and handled safely.
If nests are detected in other Algarve boroughs, the local civil protection service should be alerted.
Originally from Asia, the species is now widespread across much of Europe and is considered invasive. It preys heavily on other insects and poses a serious risk to biodiversity, particularly honeybees, due to its aggressive hunting habits. Slightly smaller than native European hornets, it can be recognised by its mostly dark body, yellow-tipped legs and distinctive orange face.
