Earlier this month, a significant discovery was made in the peaceful town of St Brelades on the Channel Island in the United Kingdom. A large Asian hornet nest was found in an abandoned house, raising concerns among locals and scientists alike. Asian hornets are considered invasive species in various parts of the world, including the UK. Authorities are urging citizens to keep an eye out for these hornets and their nests for their safety and to prevent the species from invading further.

The “Front Line” of Defense

The recently discovered Asian hornet nest in St Brelades is one of the largest seen in the UK this year, measuring about 15 inches. This nest is considered the “front line” in the battle against the invasive species and serves as the final defense to halt the wasps from invading the rest of the UK. Inside the nest were approximately 1,500 hornets, bringing the total number found this year to 171—71 more than at the same time last year. Authorities are concerned that their efforts to keep the species out of the rest of the UK may be slipping away.

Understanding the Asian Hornet’s Threat

The Asian hornet, scientifically known as Vespa velutina nigrithorax, is native to Southeast Asia but has become a growing problem in various parts of the world. This species is considered invasive due to its ability to displace local hornet populations and disrupt ecosystems. Asian hornets prey on bees, posing a significant threat to honeybee populations and the essential pollination services they provide. Additionally, Asian hornets can be aggressive towards humans, making their presence a cause for concern.

How the Asian Hornet Arrived in the British Isles

The Asian hornet’s entry point into Europe was first detected in the south of France, where it is believed to have arrived inside a nest concealed on a ship. Since then, the species has gradually spread across Europe, reaching the United Kingdom. The Channel Islands, including St Brelades, are particularly vulnerable to the presence of Asian hornets due to their proximity to mainland Europe.

Safety Precautions When Encountering an Asian Hornet Nest

The recent discovery of large Asian hornet nests in an abandoned house in St Brelades highlights the need for understanding how to handle such situations effectively. To ensure your safety and the safety of those around you, it is essential to prioritize safety when dealing with these aggressive and dangerous hornets. Here are some guidelines to follow if you come across an Asian hornet nest:

  1. Observe and Report: Do not attempt to disturb or remove the nest yourself. Take note of its location and report it to the Animal and Plant Health Agency or other appropriate local authorities, who have the expertise and resources to handle the situation.
  2. Maintain Distance: Keep a safe distance from the nest and avoid provoking the hornets. Asian hornets can be particularly aggressive when defending their nests, and their stings can be painful and potentially dangerous, especially for those who are allergic.
  3. Educate Yourself: Familiarize yourself with Asian hornet characteristics and behavior to better understand the risks involved. This knowledge can help you avoid accidental encounters and ensure your safety.
  4. Protect Your Property: If an Asian hornet nest is near your home or property, take precautions to limit its access indoors. Seal any cracks or small openings that may allow the hornets to enter your living spaces.
  5. Seek Professional Assistance: If you suspect that an Asian hornet nest is located on your property, it is advisable to contact professional pest control services. They have the necessary skills and equipment to handle the situation safely and effectively.

Remember, it is always best to leave the management of Asian hornet colonies to experts who are knowledgeable about their behavior and have the proper tools to handle them safely.


The discovery of large Asian hornet nests in an abandoned house in St Brelades, Channel Island, is a cause for concern. This invasive species has the potential to disrupt local ecosystems and pose a threat to bee populations.

It is crucial for individuals to be aware of the dangers associated with coming across an Asian hornet nest and to promptly report sightings to the appropriate authorities. By taking these precautions and seeking professional assistance when necessary, we can help mitigate the impact of this invasive species and protect our local ecosystems.
