A growing number of sightings of the invasive Oriental hornet are raising concern across Cadiz, as the species spreads rapidly along the province’s coast.

One of the latest encounters took place in Puerto Real, where a resident found a large specimen in the patio of a home in Marina de la Bahia, reports Diario de Cadiz.

After contacting local authorities, he was advised to kill it – something he managed using insecticide spray.

What shocked him most was its size: nearly four centimetres long.

‘It looked like a queen, or maybe one of those scouts searching for a place to build a nest,’ he said.

The post quickly drew responses from others claiming to have seen similar hornets in recent days, many in the same area.

The pattern suggests the species is no longer a rare sight but becoming increasingly common.

The Oriental hornet has turned Cadiz into one of the main hotspots for its spread in Spain.

Experts warn the insect poses risks both to people and the environment. Its sting can be painful and potentially dangerous, while its presence also affects local ecosystems.

The province’s warm climate and abundant food sources make it an ideal environment for the species to thrive.

Despite control campaigns by local councils and the Junta de Andalucia, efforts to contain it have had limited success.

What to do if you’re stung

With sightings increasing, knowing how to react is key:

• Wash the area with soap and water to prevent infection
• Apply cold (ice wrapped in cloth) to reduce swelling
• Take antihistamines or pain relief if needed
• Seek urgent medical help if you experience breathing problems, dizziness or severe swelling

Experts also warn against handling nests or even dead hornets, as they can still pose a risk.
