Let’s start off with one of the most disgusting insects on this list. The botfly is native to Central and South America. While it may look like a little bumblebee, how it procreates is probably one of the nastiest things you’ve ever seen. The botfly reproduces by laying its eggs in flesh, sometimes human flesh. When the eggs hatch, the larva burrows out of the skin. While it isn’t fatal, the botfly larva creates unsightly open sores in the skin. Look at your own risk.
The Japanese giant hornet is native to, well, you can probably guess. Hornets are terrifying enough, but this massive hornet can reach up to two inches in length and have a stinger that can reach up to a quarter-inch. But, what is more horrifying about this insect is that it’s sting can actually dissolve human flesh.
The bullet ant, native to Central and South America, delivers the most painful bite known to mankind. It claims the number one spot on the Schmidt Sting Pain Index (SSPI). What’s even worse is that this blinding pain can last up to 12 hours. But, there are some tribes in South America that uses these ants in initiation rituals. A boy is made to put his hands in special gloves filled with the ants for 10 minutes. Apparently, this makes you a real man.
The Africanized bee, or “killer bee” is a manmade creation. They were created in the 1950s when Warwick E. Kerr crossbred a European honey bee and an African bee. The bees later escaped and are now endemic to South and Central America. The Africanized bee is extremely aggressive and will chase you for up to half a mile. They also form massive swarms. The killer bee is responsible for thousands of deaths since their creation.
The assassin bug is the stuff of nightmares. The insect has species all around the world and deliver a painful bite. The bug is also known to transmit Chaga’s disease to humans. After the they kill their prey, they liquify and drink their insides. There’s a species of the assassin bug in Malaysia that uses the empty shells of its victims as armor.
The giant weta is simply terrifying because of its gargantuan size. The cricket-related weta is endemic to New Zealand and can weigh more than a sparrow or mouse. The insect’s name means “god of ugly things,” so that will give you an idea of how pretty it is.
Hell. Nope. Well, this list wouldn’t be complete without the largest spider in the world. The spider’s legs can reach up to a foot long, and it weighs around six ounces. The goliath birdeater, like its name suggests, eats birds. It also eats small rodents. In fact, the spider’s fangs can pierce through a mouse’s skull.
Army ants are found in the Amazon and some of the soldier ants can reach up to half an inch in length. What’s terrifying about these creatures is that they consume everything in their path. Unlike other ants, army ants are constantly mobile and move together in a giant swarm. There are reports of a colony of these ants consuming animals the size of horses.
Yes, that is a f**king spider eating a bird. The giant orb weaver is unsurprisingly native to Australia (Australia is full of terrifying critters). These spiders build extremely durable webs that are capable of entrapping large insects, and apparently birds. It then uses its venom to render the animal helpless and break down its tissue. Then the orb weaver gets to enjoy a massive feast.
The funnel web spiders in Australia are terrifying, and potentially lethal. Not only do they have massive fangs, their bite can kill a person within minutes if anti-venom isn’t administered. Between 1927 and 1980 there were 13 confirmed deaths due to this nightmare spider.
What Jewel Wasps do to cockroaches will make you squirm. The female Jewel Wasp stings the cockroach and paralyzes it. She then stings it again, directly in the brain, and injects it with a neurotransmitter called octopamine. This neurotransmitter essentially turns the cockroach into a zombie under the control of the Jewel Wasp. She then lays her eggs into the cockroach’s abdomen. When the eggs hatch, they slowly eat the cockroach from the inside. The cockroach can stay alive for up to eight days while this happens.
The brown recluse spider is found in central U.S. and the south. The initial spider bite is relatively painless, but in some cases days following the bite, the skin surrounding the bite site can die. The bite can leave a large open wound surrounded by black dead tissue. Yep, that’s enough for me to move to Antarctica.
While most people associate the mosquito as an insect that carries deadly diseases, the tsetse fly is also extremely deadly. The tsetse fly is native to Africa, and it resembles a normal housefly. But, what it lacks in terrifying appearance, it’s terrifying in what it can do to a human. The tsetse fly is a transmitter of sleeping sickness, a disease that attacks the central nervous system and can eventually lead to coma and death.
Centipedes are scary enough, on that can measure up to a foot long can just go straight to hell. The Amazonian centipede is the largest centipede in the world. While it’s bite isn’t lethal to humans, it’s still very painful. Oh, and this thing eats birds and small rodents.
Yeah, I’m bug-proofing my home and never going outside again. It’s been real.
