The invasion of the Asian hornet in Valls has already begun to receive a practical response. In just a few days, nearly 300 queens have been captured to prevent this invasive species from establishing itself.

This report comes after the first phase of the recently launched trapping campaign, aimed at controlling the proliferation of these insects that threaten local biodiversity.

The trapping campaign in Valls

Objectives and methodology

The main objective is to break the reproductive cycle of the Asian hornet, a species that can build numerous nests and damage ecosystems and crops. Capturing queens is critical to preventing new nests from being established.

The campaign uses specific traps designed to attract and capture queens before they can found their nests, focusing on areas with a high detected presence.

Preliminary results

In the first few days, nearly 300 queens have been captured, a number that highlights the large presence of the species and the urgency of the intervention.

These data have been confirmed by the Valls City Council, which emphasizes the importance of this first phase in preventing the spread of the Asian hornet in the territory.

Impact of the Asian hornet in the area

Risks to biodiversity and agriculture

The Asian hornet is a threat to native bees, as it preys on them and competes for resources. This can affect pollination and local ecosystems.

Furthermore, its presence can cause damage to crops and affect the agricultural economy of the region.

Community response and prevention

Residents are alerted to collaborate in detecting and removing nests. The campaign also includes information to prevent spread and promote citizen vigilance.

Community involvement is key to increasing the effectiveness of the measures adopted.

Monitoring and future phases

Continuous control

The first phase is only the beginning. The effectiveness of trapping is expected to increase over time, and strategies will be adapted based on the results obtained.

Constant monitoring will be maintained to detect new outbreaks and respond quickly.
