Asian hornet is one of the largest and most dangerous insects

Britain on alert as fears rise of invasion of world’s largest KILLER HORNET

FEARS have been raised that Britain has been invaded by the world’s largest KILLER HORNET – after a policeman caught a two-inch long stinging pest under a pot plant.

Fears have been raised that Britain has been invaded by the world’s largest killer hornet

Asian giant hornets have never been found in the UK before, although the smaller Asian hornets – which are twice as small as Asian giant hornets – first arrived in the UK last year.

PC Dave Wise, of Worcester Police, tweeted a photo of the two-inch long beast last week after finding it under a pot plant and catching it under a glass.

He said that the hornet was just under two inches and was the stuff of “nightmares”, adding on April 13: “We just found this beast living under soil in an old plant pot.”

He sent the photo to Defra for experts to look into what type of hornet it was, asking whether it was a deadly hornet or a “fat wasp” – although he has not had a response yet.

One of his followers on Twitter, calling herself TheycallmeLadyM wrote: “Bloody hell, it looks big enough to carry passengers.”

Craig Simpson, of Worcester, said: “If I see a hornet that big I’m running and not looking back.

Asian giant hornets have a three-inch wingspan and a stinger 0.2 inches long, which is described by victims as like having a “hot nail” driven into the skin.

Around 40 people in Japan die every year after being stung by the huge hornets – and in the Shaanxi Province in China alone 41 people died from the stings in 2013.

Those who died were stung an average of nearly 60 times.

Asian giant hornets include the subspecies Japanese giant hornets – often called the yak-killer hornet because of the power of its sting – and are the world’s largest hornet.

They normally live in Eastern Asia and create nests underground and feed on honey bees.

British wasps grow to around one-inch long, Asian hornets around 1.2 inches and European hornets around 1.4 inches.

Bosses at the London Beekeepers Association put out an alert this weekend for people to keep their eyes out for the smaller Asian hornets after several were spotted in Jersey recently – with one found in Scotland in March this year.

Hornets dwarf a group of wasps

An app called the Asian Hornet Watch app was launched by Defra in March this year in a bid to help Brits identify wasps and hornets Environment minister Lord Gardiner said in March: “This innovative new app is designed to be easy to use and allows people to report quickly any possible sightings of Asian hornets, which will help us halt their spread.

“This invasive species poses a threat to our native honey bees and we must do all we can to encourage vigilance.” It is not known yet what species of hornet PC Wise discovered – although experts at Defra are looking into it after receiving his photo of the pest.

27 Most Dangerous Bugs In The World

Updated on Apr 11, 2018

There are literally millions of different insects and bugs in the world, and while most are not rally that dangerous to us, some can kill you. The list below of 27 most dangerous bugs in the world will try to show you which bugs you want to avoid at all cost.

1. Termites

While termites are not really dangerous to humans in a basic way, the damage they cause is huge, either to buildings and homes or crops. So they made the list.

2. Deer Tick

The deer tick is the major reason for infecting people with lyme disease, we’re talking about thousands of people every year. Lyme disease starts with a small rash around the tick bite and developed into headaches and heart problems. Later on the infected body will have stiff joints and a lot of pain, however few people have died from this disease but the pain and suffering it cause is extreme, no wonder it made this list of most dangerous bugs.

Everyone knows the Black Widow spider and how dangerous it is. When the spider bites you need to get medical attention ASAP or you could actually die from the venom. However, if you receive a toxin as soon as possible, the bite will end with nothing more than mediocre pain.

4. Cockroaches

These creepy little guys that are known to be able to live through a nuclear attack ( no kidding, they can survive for months without food or water ). They can carry many harmful diseases for humans and you should be carful not to touch or let it crawl on you.

5. Army Ants

Now we’re getting serious, before you laugh at us, know that army ants are really dangerous bugs. Unlike other ant types, these are predators that actively seek prey and food, they build small colonies everywhere they go and prey on insects and other small species. Fun fact – The army ants can actually consume half a million animals each day if the entire colony goes on the hunt. Talk about a dangerous bug right?

The Most Dangerous Insects in Asia

Updated On: June 20, 2019

What are the most dangerous insects in Asia?

  1. Giant Asian Hornet – This huge insect is known to have a venom that can melt flesh.
  2. Giant Centipede – A dangerous predator whose bite can cause infection.
  3. Denki Mushi – This caterpillar species is known for its sting, which is like an electric shock.
  4. Jorou Spider – This spider is known for its bright color, gold webs, and strong bite.
  5. Rove Beetle – This tiny beetle is known for its poisonous blood, which can cause a variety of ailments
  6. Asian Giant Forest Scorpion – This aggressive scorpion is known for its signature black color and strong sting.

Asia is home to some of the most diverse flora and fauna this world would see. The continent is also home to multiple environments that range from lush rainforests, vast plains, beautiful beaches and oceans, and massive deserts. This allows different kinds of creatures to thrive and survive, which is both a good thing and a bad thing.

The good thing is that some of these creatures brings about benefits to their environment. However, the bad thing is that some of them bring about various dangers and perils to plants, animals, and humans. In fact, a number of these creatures are so destructive that you will need to call pest control just to be able to contain them.

To give you a clue, here are some of the most dangerous insects in Asia that you should stay away from:

Giant Asian Hornet

Wasps and hornets are as dangerous as they come. But this type of wasp ups the ante in terms of size and the venom that it possesses. This massive insect can grow up to 3 inches in length! They are also known as dangerous adversaries to honey bees, as around 20 to 30 of them can destroy a whole nesting.

It also has a sting that not only packs a punch, but also contains a number of dangerous toxins that react to different kinds of people. This venom is known to be able to melt flesh and release chemicals that would attract other wasps to their prey’s location. These wasps are known to reside in China and Japan.

Giant Centipede

This insect can be found in China, Thailand, and Vietnam. This is a centipede that can grow as long as 15 inches. It is a dangerous predator that has a bite that can cause some nasty infections that need to be treated immediately. It is definitely an insect you would not like to see anywhere near you.


Denki Mushi

Hairy caterpillars pack a sting when you come into contact with one of their hairs. This Japanese caterpillar, meanwhile, has a sting that is the equivalent of getting an electric shock. They might be colorful, but they sure pack a tough sting that would leave you reeling. This sting can cause skin allergies and might trigger other illnesses that may become more severe. If this happens, it would be best to seek the help of skin care services or other similar medical facilities to prevent further complications from developing.

Jorou Spider

Another scary insect that can be found in Japan; this is a spider that is easy to spot because of its bright colors. While its sting may not be as bad as the one from a black widow, it can still pack a strong punch.

This spider is also known for its golden webs, which is an indicator that you should be staying away from them as soon as you see it. In Japanese folklore, this insect is known to transform into seductive characters like women to capture unsuspecting men.

Rove Beetle

Some species of beetle are large and gentle giants, while some are dangerous insects that pack lethal stings that can kill. Unfortunately, this beetle is the latter. The Rove Beetle is from Indonesia, and can be found near bodies of water. One thing that makes it more dangerous is that it can fly, and you would not want one near you.

This beetle has a venom that is considered to be even stronger than cobra venom. It does not bite nor sting, but its blood contains a poison that can cause inconveniences like eye and skin infections. They are 8mm long, and may be hard to spot, which makes them really sneaky insects.

Asian Giant Forest Scorpions

Most people know that most scorpions live in hot deserts across the world, but did you know that there species of scorpion that can be seen in the forest? This is one of the most common scorpions that can be found in Indonesia, and are known for their black color. They are some of the most aggressive types of scorpions, and their stings are tough as well. Whenever you are strolling around the forest, it is best to keep an eye for them.

Key Takeaway

There are thousands of species of insects present in Asia alone, and all of them have their unique features that make them both fascinating and dangerous at the same time. If you happen to be near their vicinity, it is best to protect yourself, or simply run away as fast as you can.

Deadly Japanese Hornets Found In Canada May 2019

These Japanese Hornets have been found in Canada and not only pose a danger to local bee populations but are have poisonous venom that can kill humans.

A Vancouver couple found what appears to be a Japanese hornet in their home over the weekend. The giant insect, which is common in Asia but rarely seen in North America, are dangerous bee hunters. They can also be deadly to humans in rare cases.

Though humans may be safe from the insect’s deadly sting for the most part, the Japanese hornet hunts and kills bees. The effective hunter can decimate bee populations, killing over a thousand bees in three hours.

It is likely that the insect came to Vancouver through a shipping container. Hopefully, the incident is a one-off, but entomologists are concerned by the finding.

A Vancouver woman posted these photos to Twitter on Friday, May 10. The photos show a disturbingly large wasp.

Is there an entomologist in the house. This horrifying creature was caught by my bf at his work today. It’s alive & terrifying. Did some research and it appears to be a giant Japanese hornet! It can kill 1000 bees in an hr!! Are more out there? Help! @GlobalBC @chrisgailus

According to her tweets, her boyfriend found the insect earlier that day and trapped it in a glass. Shortly afterwards they froze the insect so that it could be shipped out to Beaty Biodiversity Museum in Vancouver.

According to Global News, the insect appears to be a Japanese giant hornet. It has one of the most deadly wasp venoms, and its sting is extremely painful. They regularly exceed four centimetres in length.

Though Japanese giant hornets will not often kill humans, they do kill between 20 and 40 people every year. Most of these are because of anaphylactic shock. However, even healthy people can fall victim to the sting if they get stung enough times.

The Japanese giant hornet is a subspecies of the world’s largest hornet with a wingspan greater than 2.4 inches.

— NatureWise Pest (@naturewisepest) May 9, 2019

The biggest danger posed by the insects is the threat to bee populations. The Japanese giant wasps eat the bee larvae and kill bees to get to the offspring.

According to Everywhere Wild, “a swarm of 30 Japanese hornets can take down a colony of 30,000 in less than four hours.”

The insects are not native to Canada, and their presence in the country is concerning. An entomologist who spoke to Global News stated that scientists hoped that the cold winter will kill these insects.

Until then, we’ll just have to hold tight.

World’s Biggest Hornet: Insect Behind Deadly Attacks

Experts unsure why aggressive insects are attacking people.

PUBLISHED October 4, 2013

The world’s biggest hornet is wreaking havoc in northwestern China, where 42 people have died after being swarmed and stung in Shaanxi Province, according to the Chinese news agency Xinhua.

Some 1,600 others have been injured since the outbreak of the Asian giant hornet (Vespa mandarinia) began in July, the regional health authority reported, and attacks continue even as local authorities take action, including destroying hundreds of hives and improving medical treatment for victims. (Watch a video of “hornets from hell.”)

“The problem with this particular hornet is that it’s big, sort of thumb-sized, and it packs a lot of venom,” said entomologist Lynn Kimsey, director of the Bohart Museum of Entomology at the University of California, Davis.

“And its nests get fairly large, including maybe several hundred individuals. They are aggressive, they are predatory, and they have been known to kill and eat an entire colony of honeybees,” she said.

At 1.5 to 2 inches (4 to 5 centimeters) long, the giant hornets are found across many parts of East and Southeast Asia and are especially well known in Japan. They’re among the more dangerous venomous insects of their type, Kimsey said, though others, like Africanized bees and yellow jackets, can cause similar problems.

Bee-Loving Hornets

While the hornets don’t typically swarm humans in such numbers, they’re well known for their ability to quickly decimate a hive of thousands of honeybees, leaving behind a trail of severed heads and limbs.

The hornets routinely fly miles from their nests and employ scouts to locate a bee colony and then mark it with a special pheromone that attracts their allies to attack, destroy, and occupy the hive.

With their huge size advantage, the hornets typically make short work of the bees, unless the victims are able to eliminate the advance scout before it can summon others. They sometimes do so with an incredible defense—swarming the hornet in a ball and literally cooking it to death.

Often, however, the bees and other insect victims become fodder for the growth of the hornet hive. Adult workers chew their victims’ flesh into a nutritious paste that feeds larvae, which in turn produces saliva that serves as a powerful “energy drink” to be consumed by adults who cannot digest solid protein.

Why Are Hornets Attacking People?

It’s unclear exactly what factor or factors has led to the hornets’ deadly season of human attacks.

Huang Rongyao, an insect expert with the Forestry Bureau of Ankang City, told Xinhua that local vegetation growth has increased hornet habitat, and that two months of hot weather have made the insects much more active. Ankang is one of the cities most affected by hornet attacks, along with Hanzhong and Shangluo.

Hua Baozhen, an entomologist at China’s Northwest Agriculture and Forestry University, pinpointed a decrease in populations of the insect’s natural enemies like spiders and birds, while other experts speculate that urban sprawl simply means more people are living in what was formerly hornet country.

Kimsey noted that this type of behavior is often seen with invasive species, though she’s not sure if the hornet is native to the region or how long it may have been there.

“What we see happen when you get a newly introduced species is that it may sort of go along relatively unnoticed for years, but then eventually you see a huge outbreak. We have that happening in California, where the European paper wasp was introduced 20 years ago, and now suddenly it’s an outbreak and they are everywhere.”

If the hornets are in fact natives, Kimsey added, this year’s weather probably does play a major part in the outbreak. “In that case I’d suspect that they had a very mild winter and spring, so that a lot of queens survived and consequently they now have many more nests than they normally would have.”

That scenario also has parallels in the U.S. she added, like the western yellow jacket, whose numbers have risen to “spectacular” levels in California due to recent milder weather. (Also see “Stinging Wasps Moving North Due to Warming?”)

Mating Season

In addition, autumn is mating season for hornets, which can make them more aggressive, particularly toward the end of the process, UC-Davis’s Kimsey said.

“Right now if it’s getting towards the end of the season, they are irritable. They are not producing a new brood, and there are a lot of workers not doing much of anything.”

Once a queen has been fertilized, a typical hive begins to shut down with the approach of cool weather; the workers will die off while the queen finds a place to overwinter.

Xinhua reported that hives in the region typically go dormant by December, though attacks are expected to taper off sooner, perhaps by the end of the month. In the spring, hornet queens will begin new nesting colonies with offspring numbering in the thousands.

Deadly Attacks

In the meantime, staying well clear of the hornets is the best route to safety, experts advise, but that’s often easier said than done.

The insect often locates nests underground or even on buildings, which puts them directly in human territory. Disturbing them or merely passing too close for the hornets’ comfort can unleash a fierce retaliation. Some attacks seem especially unprovoked. In September, Xinhua reported that a swarm attacked a school in southern China, injuring 30 people—all but one of whom had to be hospitalized with multiple stings.

“If you inadvertently disturb a nest, they will come out en masse and you could get lots and lots of stings,” Kimsey said, noting that the insect is proving deadly in much the same way a swarm of Africanized honeybees might. (Watch video: “Beware the Giant Hornets.”)

“Even if you’re not allergic, the amount of foreign protein that circulates in your blood after so many stings can cause kidney failure. It’s like sepsis, and if you don’t get on dialysis you can die.

“People are probably dying because they aren’t receiving the appropriate treatment in time,” she added.

“And many Chinese doctors probably don’t know exactly how to treat this problem, just as many doctors wouldn’t in this country.”

7 facts about hornets

Like a B movie from the 1970’s, the media overseas has been full of headlines around giant killer asian hornets making their way across Asia and Europe. The shocking factor behind these stinging insects is how painful and life threatening their stings can be. But did you know hornets are so much more than ultimate killing machines?

Trying to get rid of hornets or other stinging pests on your own can be risky. Done improperly, you can end up stung by the hornets or wasps you are trying to get rid of.

1. Gentle giants

A little known fact about hornets as they are actually not as aggressive as one might think.

Like most nest building insects, hornets will usually only attack to defend their colony when they feel it is being threatened. This is mainly only when someone or something comes within close proximity of the nest (the radius of this is usually 2-3m) .

Outside of their nest area hornets have been known to be quite passive creatures. It has been noted by some researchers that hornets are shy, peaceful creatures. They tend to avoid conflict and only attack when they absolutely have to.

2. Wasp vs hornet: hornets are actually wasps

Did you know hornets are actually a subset of wasps. In particular, hornets are a breed of social wasps, living in large, highly organized, colonies.

Hornets belong to the insect family Vespidae. This family contains each species of hornets as well as wasps such as yellow jackets, paper wasps, potter wasps and pollen wasps.

Fun Fact – Bald faced hornets are actually wasps, and do not belong to the hornet family.

The main difference between wasps and hornets is their size. Hornets are relatively larger than wasps, which is one of the main reasons they are so scary, although as previously discussed, they are quite shy. Another difference is the color. Wasps which are usually yellow and black, hornets fare more orangey-red, although this does vary with each species.

3. Hornets nest below ground

So where do hornets create nests? That depends on the species.

Typically, hornets like to build their nests in high areas. These include, but are not limited to:

  • Attics
  • Treetops
  • Under roofs
  • Decking
  • Sheds
  • Garages
  • Hollow tree trunks
  • Areas that are raised off the ground.

Hornet nests which are elevated are sometimes free-hanging, using a stalk called a petiole which attaches to the nearest object such as a tree branch.

Hornets nest in the ground

Asides from high places, hornets are also known to build their nests in enclosed spaces that provide support and security. Sometimes this can be old, abandoned rodent burrows.

Located within fields, gardens and parks, hornets that build their nests in the ground cause a real risk to humans. Hornet’s nests built in the ground in areas highly populated by humans runs the risk of getting stepped on by accident, causing the hornets to attack the unsuspecting human.

4. Natural pest controllers

Hornets are one of mother nature’s pest controllers. With a craving for insects such as aphids, hornets help rid the world of unwanted garden pests which damage resources within an agricultural setting.

What do Hornets eat?

Hornets are known to have a rich diet of sugar and protein among other things.

  • Sugar – Like other types of wasps, hornets have a real sweet tooth and crave sugary things such as fruit and fizzy drinks.
  • Sap – Hornets love tree sap! You can often find them using their mandibles to pull back the bark from trees to get to the sticky golden substance.
  • Protein – Just like other insects within the Vespidae family, their young live off protein which the workers forage for in the form of insects and other animals. In return, the larvae releases a sweet syrup which the adults lap up.

5. Hornets love bees!

Bees are one of a hornet’s favorite things. Not only are they a great source of protein for their future queens, but they provide a sweet, golden, sugar goodness which hornet’s love – honey!

Nearly 5 times the size of a European honey bee, it only takes a small number of giant hornets to wipe out an entire honey bee colony. Their sheer size and power means that one giant hornet can kill roughly 40 bees a minute.

Hornets are usually gentle giants, but they can also be dangerous. In particular they can be dangerous for bees.

However, Japanese honey bees have developed a cunning tactic to stop these predators from wiping out their colony. As a hornet scout approaches the hive, the honey bees attack her before she can release any pheromones to attract her team mates. A honey bee’s sting and bite is no match for a hornet, so instead they swarm around the lonesome hornet, vibrating their bodies at a tremendous rate. The vibration from the bees causes the temperature to drastically rise, roasting the hornet alive.

This technique is the result of evolution over hundreds of years. Honey bees from the rest of the world have yet to discover this defense mechanism, making them prime targets to giant hornets as they make their way across the globe.

6. Hornet stings: hornet venom can be deadly

The one underlying factor which makes hornets so dangerous is their sting. Although, the likelihood of getting stung by a hornet is very small, when they do decide to attack, it can be fatal.

The main reason a hornet’s sting is so deadly compared to other stinging insects is due to the sheer size of a hornet. Generally, hornet venom isn’t considered that toxic to humans, but due to their size, the amount of venom they release per sting can be harmful. Hornets release more venom per sting than any other stinging insect.

Giant Asian Hornets

These giant stinging insects are loving the spotlight at the moment. Originating in Japan, the giant Asian hornet has quickly made its way across Europe. With a long stinger, and a venom that contains powerful chemicals that can cause havoc to human tissue and nervous systems, these peaceful creatures shouldn’t be messed with.

7. Hornets are a delicacy in Japan

Although hornets are responsible for a percentage of hospital visits in Japan, that doesn’t stop them from snacking on these predatory stinging insects. In many Japanese mountain villages, hornets are considered a delicacy, especially hornet larvae. Often eaten either deep fried or raw, hornets provide a huge amount of protein.

Anyone wanting to try hornets at Pestaurant next year?

Hornet larvae produce a sticky, sweet segregation known as vespa amino acid mixtures (VAAM) which attracts the workers and gives them energy. VAAM is also used in a popular Japanese energy drink.

If red bull gives you wings, what would a hornet energy drink give you?
