Urgent warning over surge of giant Queen wasps with bigger stings amid fears of ‘deadly reactions’

A SURGE in giant wasps is expected to bring a rise in the number of people suffering deadly reactions, experts warn.

Queen wasps — nearly twice the size of ordinary wasps — have surged in numbers after surviving the milder winter in Britain.

They have larger stings than their smaller counterparts, which cause searing pain.

In more severe cases, they can cause deadly anaphylactic shock in people who are allergic to them.

Dr Avinash Hari Narayanan, clinical lead at London Medical Laboratory, said: “More wasps mean it’s more likely that people will be stung. 

“In turn, this increases the chances of severe allergic reactions or even, in rare cases, anaphylactic shock.”

Anaphylaxis — a severe response to a trigger like wasps’ venom — occurs in up to 65 per cent of people who suffered a strong allergic reaction the last time they were stung.

It is caused by the body's immune system overreacting, and can be set off by allergies to anything from foods, like nuts or shellfish, to general anaesthetic.

Warning signs include feeling lightheaded or faint, difficulty breathing, a raised heartbeat, clammy skin and confusion or anxiety.

If someone is suffering from it, you should use an adrenaline auto-injector on them if they have one and you know how to use it, according to the NHS.

Ambulances should also be rung immediately and you should remove the sting from them if possible.

Anaphylactic shock from wasp or bee stings causes around nine deaths a year in the UK normally.

But Dr Narayanan warned the risks may be greater this year, with more wasps out looking for nests in April than any other month.

Queen wasps usually measure up to 2.5cm in length, whereas an ordinary worker wasp can be as little as 1.2cm long.
