This terrifying video shows the world’s biggest wasp in action as the UK braces for an invasion of Asian hornets.
The giant hornet, native to Asia, is said to be the size of a matchbox and is one of the most venomous insects in the animal kingdom.
In this clip from National Geographic WILD, the killer hornets, which are five times bigger than the honey bees they hunt, are seen ripping the heads off their prey as they invade a nest.
A horrifying close-up shows its stinger – measuring a quarter of an inch long – as the narrator explains it contains an enzyme that destroys tissue.
People who are allergic to this enzyme can die from anaphylactic shock if stung.
The hornet colony only exists for six months of the year but in that time it will kill an average of 40 people, according to the shocking documentary.
In another shot, a female giant hornet is seen ripping a praying mantis to shreds while it's still alive and chomping it down into a "gooey substance" to feed her offspring.
The clip has been watched more than 1.5 million times on YouTube and viewers have no plans to come face-to-face with one of the lethal insects any time soon.
A shocked person wrote: “If I saw that in my room, I’m moving to another dimension. No regrets.”
Upset at the plight of the bees, another person commented: “Imagine having your bottom half torn off and eaten by a hornet twice your size and still be alive.”
“Never have I ever wanted a flamethrower more than right now,” said a third viewer in horror.
But a woman who was a fan of the deadly insects had a rather contrasting opinion and said: “An exceptional, and very beautiful insect, wonderful images and footage of it here in its natural habitat.
“A creature only to be respected and admired.”
