The Balearic Government has confirmed the presence of the oriental wasp (Vespa orientalis) in Mallorca. This is a new invasive species detected for the first time in the Balearic Islands. The first nest was found in Esporles, in the Ses Rotgetes de Canet area, and was removed during the second week of October.
In addition, a specimen had already been captured in Binibona (Selva) in spring, suggesting the possible arrival of this species on the island. Following confirmation, the Ministry of Agriculture, Fisheries and Natural Environment has activated the control and monitoring protocol for invasive species.
What is an invasive species?
An invasive species is one that is not native to the ecosystem in which it appears and can alter the natural balance, affect the native fauna, and cause environmental impacts.
In the case of the oriental wasp, its presence poses a risk to bees and other pollinating insects, which are essential for both the environment and agriculture.

Asian wasp control campaign
At the same time, the Ministry has concluded the 2025 Asian wasp (Vespa velutina) control campaign.
This year, 21 nests have been located and removed in the southwest of Mallorca as part of an intensive trapping and continuous monitoring programme.
During the spring, more than 1,000 traps were installed, which allowed the capture of 20 queens.
The campaign, funded with €28,000 from the Next Generation EU funds, strengthened fieldwork between March and May.
For the first time, an autumn trapping programme has been launched to capture new queens before they form nests next spring, thereby reducing the chances of reinfestation.
These actions are part of the control and possible eradication plan for the Asian wasp, declared eradicated in 2021 but reappearing in recent years.
Monitoring and surveillance are carried out through the joint work of the Species Protection Service, the Consortium for the Recovery of Fauna of the Balearic Islands (COFIB), and the University of the Balearic Islands (UIB).
Public cooperation
The Ministry reminds that public cooperation is essential for the early detection of nests. If you spot an Asian wasp or an oriental wasp, you should report it to the Species Protection Service via email:
