25 Of The Scariest Insects In The World

25. Georgian Speekle


They’re creepy, they’re crawly, and they’re downright scary.

You won’t want to run into any of these 25 terrifying insects at night!

This monster-looking thing measures TWO FEET in length and was only recently discovered. A homeowner found one crawling around in her garage, and experts said they had never seen one before.

24. Scutigera Coleoptrata

While not poisonous, this creepy crawler is an unwanted visitor that put a lot of fear into homeowners in Georgia.

These centipedes, which can have up to 15 pairs of legs, live and thrive in people’s homes. They even kill and eat spiders.

23. Asian Giant Hornet

That may be a good thing, but when you stop and consider a spider-killing centipede living in your house, it’s enough to send chills down your spine.

As the world’s largest hornet (as if that isn’t scary enough), the Asian Giant Hornet attacks and kills other insects. This includes launching full-on assaults on beehives!

22. Ghost Mantis

They feed on these larger insects and honey, and they also are capable of injecting large amounts of potent venom. No, thank you!

The Ghost Mantis is made to resemble a dead leaf to better camouflage with its surroundings. Imagine having one of these things fly at your face unexpectedly!

21. Giant Orb Weaving Spider

21. Giant Orb Weaving Spider

These Australian spiders, which can grow to the size of your hand, catch and eat birds. Plus, they’re venomous— of course— so that’ll be a hard pass on coming across one of these monstrosities.

20. Saddleback Caterpillar

19. Tarantula Hawk Wasp

20. Saddleback Caterpillar

These guys may look pretty, but they’re also super poisonous. Their hairs and spike-y spines are filled with venom— venom that they can’t wait to inject into you if you get too close.

18. Titan Beetle

A tarantula-hunting wasp that is known to have one of the most powerful and painful stings of all insects— yeah, that accurately describes the Tarantula Hawk Wasp. 

A beetle as big, if not bigger, than your hand? Yes, they do exist.

17. Botfly & Botfly Larvae

The Titan Beetle can grow to almost seven inches in length and have a powerful bite. They’re also known for their hissing, which usually means they’re getting ready to attack a perceived threat.

Botflies implant their larvae under skin. Human skin. Then, about a week later, a maggot wiggles its way out of your skin.

16. Sand Fly

It’s as nightmarish as it sounds. Feel free to search for images online, but we thought we would spare you.

These little flies carry not-so-little diseases, such as Leishmaniasis.

15. Giant Katydid

This illness causes ulcers and enlarged organs, and is also known as “black fever.”

While these big bugs won’t harm you, they are quite intimidating to come across.

14. Giant Stick Insect

Native to Cuba, these giants are sometimes kept as pets, and any insect that is large enough to be considered a pet, is an insect you probably don’t want to meet.

These elongated insects normally range from four to five inches, but have also been known to grow much larger (as pictured.) They resemble sticks, therefore effectively camouflage into surroundings.

13. Bullet Ant

You won’t know one’s around until it’s landing on you.

12. Brahmin-Moth Caterpillar

Just one bite from this teeny-tiny insect has been described as “waves of burning, throbbing, all-consuming pain that continues unabated for up to 24 hours."

This crazy-looking caterpillar made a list for top three scariest caterpillars you’ll even encounter.

11. Giant Weta

We can only imagine what running into one of these things would be like as they seem to be straight out of a horror film. 

These things are basically giant— no, HUGE— grasshoppers.

10. Giant Centipede

Most people have an aversion to any insect that is fast and can jump at them, so multiple that by ten to get this behemoth of an insect.

The Giant Centipede’s name explains it all. This beast can grow up to a foot long, and eats things such as birds, snakes and bats.

9. Giant Isopod

A centipede that eats SNAKES!


Considered the largest isopod in the world, you probably won’t run into one of these “insects” anytime soon, but that doesn’t make them any less frightening. They’re related to the pill bug, and average in length to over a foot long.

8. Kissing Bug

While they reside in the deep, dark ocean, they do become entrapped in fishing gear and brought to the surface where fishermen most likely faint from fear.

These bugs usually nest with animals so they can continue to feed on their blood. Kissing Bugs suck the blood from around the mouth area, even on humans, which is where they get the name.

7. Camel Spider

They can cause Chagas disease, which can lead to digestive heart failure. 

Camel spiders are closely related to scorpions and grow to about six inches long.

6. Goliath Spider

Their particular looks make them one of the creepiest insects you may stumble across late at night.

Also known as Goliath birdeater, the Goliath spider grows to be about a foot long and have one inch long fangs. They trap their prey in silk webs and have a bite that resembles a bee sting.

5. Flea

They’re reportedly the second largest spider in the world and have a lifespan up to 25 years. You can find these creepy guys in deep burrows and marsh lands in South America.


Most people are familiar with fleas, unfortunately, and most people know the diseases these tiny insects can harbor. One of the worst things about these pests is their size.

4. Wasps

Fleas are small enough to go undetected until you feel that itchy sensation.

There are a few different types of wasps. One, which is known as a predatory wasp, kills and eats insects and animals. They will even feed said animals to their larvae.

3. Tick

Then there are the parasitic wasps, which lay their eggs in living bodies of other insects, such as caterpillars and spiders. Go ahead and Google parasitic wasps and tell me you still don’t find them menacing.


Humans have a natural aversion to these little bloodsuckers. Not only do ticks carry illnesses and disease, but they can also be painful to remove.

2. Orchid Mantis

Plus, they can live on a host for weeks without being detected. 

The Orchid Mantis may be beautiful, but it’s also ruthless in catching and consuming prey.

The resemble an orchid flower, obviously, and use this to their advantage when it comes to ensnaring prey.
