People don't particularly like insects. They sting and bite. They inject poison that can kill instantly or cause a fatal allergic reaction. Mosquitoes, for example, spread parasites that kill hundreds of thousands of people every year.

To be clear, the list below is not taxonomically accurate. Spiders and scorpions are not technically insects, but we decided to include them because the main criteria for selection were to look creepy, crawl, and be deadly.


1. Mosquitoes

Mosquitoes are considered the deadliest creatures in the entire animal kingdom. They kill 700,000 people every year. Mosquitoes carry many dangerous diseases, including malaria, dengue fever, West Nile virus, yellow fever, Zika virus, Chikungunya virus, and lymphatic filariasis. Malaria is a serious problem: in 2017, 435,000 people died from this disease worldwide. Mosquitoes have a special organ called the maxillary tentacle. With its help, they detect carbon dioxide released as a result of breathing and fly towards us to consume blood in an amount three times greater than their own weight. Mosquitoes are known to prefer beer drinkers, as it increases the ethanol content in sweat. Ethanol excites mosquitoes. Moreover, alcoholic drinks increase your body temperature, due to which it is easier for mosquitoes to find you. People with a higher body mass are attracted to these insects for the same reason. Mosquitoes also prefer people with blood type O. No one knows exactly why, but it is thought that people with blood type O smell better - at least to mosquitoes - than everyone else.

2. Triatomine bugs

Triatomine bugs are also known as "kissing bugs" or "vampire bugs" for their tendency to bite people around the soft tissues of the mouth. These insects carry Chagas disease, which is thought to have originated in Central America. It kills about 12,000 people worldwide each year. Victims typically experience no symptoms for four to eight weeks. Even in the chronic phase, most people experience few symptoms, but 45 percent develop heart disease 10 to 30 years after contracting the infection, which can lead to heart failure.

3. Tsetse Fly

Native to tropical Africa, these large, biting flies spread a parasitic infection that causes African trypanosomiasis, a disease that is 100 percent fatal if left untreated, and treatment is extremely difficult. There are medications, but they must be administered with great care, and there is always a risk of parasite resistance. When bitten by an infected tsetse fly, a person experiences symptoms such as confusion, poor coordination, numbness, and difficulty sleeping. They are very likely to die. Because the disease is so deadly, efforts are being made to eradicate the insects themselves, which is gradually reducing the number of cases. African trypanosomiasis used to kill up to half a million people each year, according to some estimates. In 2015, the death toll was 3,500.

4. Bees

Anaphylactic shock is deadly, and about 80 percent of those who die from it are men. Any kind of bee, hornet, or wasp sting can cause an allergic reaction, but these days the creature you most often hear about is the Asian giant hornet, or Japanese giant hornet. It is the largest in the world, measuring just over four centimeters long and with a wingspan of about eight centimeters. Its stinger is 6.5 millimeters long. In some parts of Japan, fried hornet larvae are considered a delicacy. In others, adults are grilled on skewers until crispy. Yum! The Japanese giant hornet was spotted in the Pacific Northwest in 2019, meaning Americans can eat it too if they want. Another famous bee in this category is the so-called "killer bee," a term coined by the media to describe the African, or Africanized, bee that is responsible for one or two human deaths a year worldwide. This bee's sting is no worse than most other honey bees. The difference is that Africanized bees are much more aggressive and sting proportionally more often — about ten times more than other bees.

5. Indian Red Scorpions

There are about 1,500 species of scorpions, of which only a few dozen are venomous. The Indian red scorpion is the deadliest of all; up to 40 percent of victims it stings die. This scorpion is a serious problem, especially in India, Sri Lanka and Nepal, as it is often found near human habitations where barefoot children play. Scorpions are shy, nocturnal arachnids that sting when they feel threatened. Despite being less than eight centimeters long, the Indian red scorpion produces a powerful venom that causes severe pain, vomiting, sweating, shortness of breath, and alternating high and low blood pressure and heart rate. The venom attacks the respiratory system and heart, and can lead to death from pulmonary edema. Antivenom is virtually ineffective, although the blood pressure drug Prazosin has been found to reduce the mortality rate to four percent. Despite the danger they pose, Indian red scorpions are often kept as pets in India. Perhaps because they, like most scorpions, glow under a black light.

6. Yellow Scorpions

The yellow scorpion is another highly venomous scorpion found from North Africa to the Middle East and Central Asia. A single sting is unlikely to kill a healthy adult, but it can be fatal to children, who then require massive amounts of antivenom. (Doctors who rarely deal with scorpion and snake bites often make the mistake of assuming that children require less antivenom because they are smaller in body mass. In fact, children require much more because the venom-to-body-weight ratio is much higher than that of adults.) The yellow scorpion's venom is a mixture of four powerful neurotoxins that can cause heart failure. In 2010, Air Force Staff Sergeant Monique Munro-Harris was stung by a yellow scorpion in Kirkuk, Iraq, and was subsequently sent to Balad Air Base and then to Germany. Her blood pressure dropped to near zero several times during the flight before she was given the anti-venom. Her nickname is now "Scorpion Queen." Yellow scorpion venom is also famous for being the most expensive liquid in the world, costing $39 million per gallon. That's because it's hard to obtain. It takes about 2.64 million scorpions to milk a gallon of the venom. Another reason it's so expensive is because it's been shown to be effective in treating brain cancer, arthritis, and bone disease.
 
7. Black Widows

There are 32 species of black widows, including western, southern, and northern, as well as red, gray, and brown. They are found on every continent except Antarctica. Females are usually dark in color, often with red, white, or brown markings on their abdomens. In some species, they can be hourglass-shaped. Black widows are usually small, but they produce an unusually potent venom containing larotoxin, a neurotoxin that can cause pain, muscle rigidity, vomiting, and sweating. Symptoms typically last three to seven days. Only the bite of the female is considered dangerous to humans. Each year, about 2,200 people report being bitten by a black widow. There have been no fatalities since 1983.
 
8. Brazilian Wandering Spiders

If a Brazilian wandering spider happens to wander into your home, you’ll definitely notice it because its leg span is about 18 centimeters. Found in South America and parts of Central America, it is also known as the banana spider because it is sometimes found in crates of bananas shipped to other countries. Brazilian wandering spiders are often found in homes, cars, shoes, boxes, and other places. They are nocturnal hunters that hide during the day instead of spinning webs. They belong to the genus Phoneutria, which means “killer” in Greek. The Guinness Book of World Records lists the Brazilian wandering spider as the most venomous in the world, and while it rarely kills humans, its bite is incredibly toxic and can cause intense burning, sweating, and goosebumps, followed by high or low blood pressure, nausea, hypothermia, blurred vision, dizziness, and seizures.
 
9. Brown Recluse Spider

The brown recluse spider is a small, shy creature that is often found in attics and basements. Like the black widow, its reputation as a killer is greatly inflated. And while it is theoretically possible to die, there are no documented cases of death from a brown recluse bite. On the other hand, a bite from this spider can actually hurt you. This is because it produces necrotic venom, which kills tissue. As a result, an untreated bite can create a gaping, bloody hole in your flesh and lead to amputation. In severe cases, the venom can cause red blood cells to rupture, which is not good. Treatment usually involves immobilizing the limb, applying ice, and a tetanus shot. Fun fact: Brown recluse spiders can survive for ten months without food or water. They can be identified by the presence of three pairs of eyes instead of four, unlike most other spiders.
 
10. Ants

Yes, ants can kill you, although it is highly unlikely. They are also capable of delivering extremely painful stings. Three species on the "worst ants" list are fire ants, Dorylus and Paraponera clavata. Fire ants live in colonies and build nests in open areas, feeding mainly on young plants and seeds. However, they will attack and kill small animals. Fire ants inject a toxic venom into their victims, consisting of oily alkaloids mixed with small amounts of toxic proteins. The sting, which feels like a flame burn, usually quickly turns into a bump, which can cause pain and skin irritation. Some people may develop an allergic reaction to the venom, sometimes leading to anaphylactic shock, which can be fatal. Dorylus ants belong to a large genus of army ants found mainly in Central and East Africa. They form colonies that can number up to 20 million ants. Potential problems arise when they run out of food and form large columns that attack everything in their path. Larger ants have strong jaws and deliver a very painful bite that leaves two puncture wounds. Paraponera clavat ants, found in tropical forests from Nicaragua to Paraguay, are called "bullet ants" because their bite hurts so much that it feels like you've actually been shot. The pain is searing, throbbing, all-consuming, and lasts up to 24 hours. The Satere-Mawé people of Brazil use bullet ants in their warrior initiation rites. Eighty Paraponera clavat are woven into leaf gloves, which a boy is given to wear. The goal is to keep them on for five minutes. After that, the boy's hands are temporarily paralyzed by the ant's poison, and he may tremble uncontrollably for several days. Over the course of several months or years, the boy must go through this ordeal 20 times to become a warrior.
 
11. Fleas

Fleas are like people who have different opinions than you. In other words, they are small, wingless, blood-sucking insects. They can also give you the plague. The plague, which struck Europe in the 14th century, killed an estimated 25 million people. The World Health Organization estimates that there are between 1,000 and 2,000 cases of plague each year, but the actual number is likely much higher. True, the disease can now be effectively treated with antibiotics. Of the 3,000 species of fleas worldwide, only about a dozen are considered harmful to humans, causing plague and/or a type of typhus. The most notable species are rat fleas, human fleas, and cat fleas. But these names are misleading. For example, cats, dogs, and people are regularly infested with cat fleas, and cat fleas are more common on dogs than on dogs. Human fleas prefer the blood of humans and pigs. Fleas breed near the host's resting and sleeping areas, especially in dust, dirt, carpets, and cracks in floors and walls. Adult fleas can go for months without food.
 
12. Ticks

Everything in nature has its place, except ticks, which should be killed as soon as you find them. That’s because ticks can infect you with a variety of pathogens: bacteria, viruses, and protozoa. Any given tick can carry a variety of pathogens, making diagnosis and treatment more than a little challenging. Our understanding of tick-borne diseases is still in its infancy. There are 16 such diseases, four of which have been discovered in the last seven years. Lyme disease gets the most attention, and for good reason. However, the deadliest is Rocky Mountain spotted fever, which has a mortality rate of 30 percent. Those lucky enough to survive can be left with lifelong complications. Rocky Mountain spotted fever is most common in North Carolina, Tennessee, Oklahoma, Arkansas, and Missouri. Its symptoms can be similar to other diseases; These include fever, headache, nausea, vomiting, muscle pain, etc. There is no vaccine, but it can be treated with antibiotic
