Asian hornets have already killed people across continents. Now, experts warn that more of them could be on their way to Britain because of the warm spring season.
Measuring almost three inches long, Asian hornets are more vicious than smaller varieties of the insect. They also carry a more powerful and toxic sting composed of eight chemicals that could result in allergic shock in humans.
Six people in France have so far died from anaphylactic shock after they were stung by these insects that originated from China but have already spread in many parts of the world, including Portugal, Spain and France, where it is believed to have traveled on some Chinese pot plants in 2004.
The hornets also target honeybees, picking them off as they leave their hive until the colony becomes too exhausted that the hornets can ransack it. Now, the threats posed by these hornets are set to be discussed at a summit meeting of beekeepers.
The National Bee Unit of the UK's Department for Environment, Food and Rural Affairs (Defra) will meet in Suffolk next month for a seminar that will discuss ways to deal with these predators that, individually, can devour as many as 40 bees per minute. Defra has sent email alerts to beekeepers across the country, urging them to be on guard for this menace.
"They can absolutely decimate colonies and we are concerned that it is going to come in on someone's caravan who has been traveling in France," said Norfolk Beekeepers' Association chairman Carolyne Liston.
The public has also been asked not to approach the nests of these insects, which can often be found on the sides of buildings and in trees. Most people die after they disturb a nest and get stung several times, which can result in a deadly reaction in those who have allergies. A 54-year-old man, for instance, died when he was attacked by a swarm after he disturbed their nest.
If a hornet or its nest is accidentally disturbed, running would not be a good idea because the insects can fly faster. Experts advise crouching low on the ground, not moving and covering the head.
Insect research professor Li Xin from the Northwest Agricultural and Forestry University said that hornets see running as a form of provocation.
Hornets are also intrigued by moving targets. They are likewise drawn to the smell of cologne and perfume and are agitated by the alcohol's smell.
