The wasp was eliminated with the resolution of all reported cases, according to a statement from the municipality in the district of Porto.
The work has been carried out in partnership with the Associação Nativa - Natureza, Invasoras e Valorização Ambiental.
"The effectiveness of this service, guaranteed and paid for by the municipality, allowed us to act promptly and resolve the problem of the Asian wasp throughout the county", points out the Civil Protection councillor, Elias Barros, quoted in the statement.
At the beginning of the year, about 100 traps were placed to capture Asian wasps, a measure that, according to the councillor, allowed "to act early in detecting the invasive insect and contribute to the rapid response in its eradication".
The velutina wasp, better known as the Asian wasp, arrived in Portugal in 2011, in Viana do Castelo area. From then on, it began to expand to the rest of the country.
According to the Action Plan for the Vigilance and Control of Wasp Velutina in Portugal, the main known impact of this species is the predation of bees.
“When disturbed, this species may also pose a risk to people, due to its sting, as with other wasps and bees”, adds the document.
