The 10 Most Dangerous Insects in the World 

You never want to meet these most dangerous insects in the world. If insects do not bite and do not bother with their buzzing, then we perceive them as harmless and even cute creatures. But in nature, there are very scary, dangerous, and poisonous species, which it is better to know and avoid.

If insects do not bite and do not bother us with their buzzing, then we perceive them as harmless and even cute creatures. But there are some very frightening, dangerous and poisonous species in nature that we’d better be aware of and avoid.

Most Dangerous Insects in the World:

1. Tsetse fly

Tsetse fly

It’s the most dangerous insect in the world. This is a blood-sucking insect, but unlike mosquitoes, the tsetse fly leaves devastating consequences after the bite. The tiny teeth literally gnaw into the victim’s skin, and the flying predators also carry nasty infections like African trypanosomiasis (sleeping sickness). If not treated promptly, the disease can be fatal. There are more than 20 varieties of tsetse flies, most of which live in Africa, have a yellowish or ochre color, and can be up to 1.5 cm long.

2. The caterpillar of the peacock-eye fly

The caterpillar of the peacock-eye fly

The frightening-looking peacock-eye caterpillar is a dangerous species: Several people die each year from its bite. This inhabitant of the South American continent releases a strong poison contained in the bristles, which causes gangrene and hemorrhages. The insect is called the killer caterpillar for its insidiousness.

3. Giant Scolopendra

Giant Scolopendra

Another dangerous creature can be found in South America and the Caribbean islands – the giant Amazonian scolopendra. Its body consists of 21-23 segments with legs and reaches a length of 35 cm. This aggressive arthropod attacks animals and humans by grabbing a leg or arm with all its limbs and plunging its claws. It is not fatal, but pain, weakness and fever are assured.

4. The American Reaper Ant

The American Reaper Ant

The American Reaper is one of the most dangerous insects in the world. The American reaper ant is the most poisonous insect in the world: its toxin is 12 times stronger than the bee’s toxin. Twelve injections are enough to kill a rat and 350 to poison a human. The ant attacks the victim and “bites” with its pincers, while injecting pheromones from its stingers together with the venom: in this way it attracts its fellows to finish off the uninvited guest. The stung person feels very severe pain, it lasts 4-8 hours.

5. Human skin gadfly

Human skin gadfly

The insect looks similar to a bee, only it has fewer bristles and more hairs. The female inserts her eggs into the skin of humans, wild parropods, and livestock, attaching them to vectors such as mosquitoes and flies. Once on the body, the larvae feel the heat and hatch, then penetrate under the skin and develop there. (We hope you’re not chewing on a sandwich right now while reading.)

6. Asian giant hornet

Asian giant hornet

The Asian giant hornet is one of the most dangerous insects in the world. The world’s largest species of hornet, known for its particular fearlessness and aggressiveness, lives in East Asia: it can often be found in the mountains of Japan. This insect feeds on the larvae of honeybees, for which the hornets ravage hives. This predator is capable of tearing apart up to 40 bee larvae in a minute with its powerful mandibles, and its 6-mm sting contains venom that dissolves body tissues.

7. Bullet Ant

Bullet Ant

The world’s largest ant gives the most painful jabs of any insect. It can be found in Central and South America. The ant’s name comes from the very intense shooting pain caused by the venom that exudes from its stomas. The suffering can last as long as 24 hours.

8. Fluffy caterpillar

Fluffy caterpillar

Fluffy caterpillar is one of the most dangerous insects in the world. The appearance of this caterpillar is quite unusual – it looks like a mop of hair the color of ochre, gray or yellow. While this creature looks cute and you want to pet it, touching it is strictly forbidden. The furry little lump, nicknamed the most poisonous of the caterpillars in the United States, can cause excruciating throbbing pain with its sting, swelling and burning of the skin, as well as cramps in the head and stomach.

9. Wandering Ants

Wandering Ants

Huge colonies of ants (up to 22 million in number) live in the forests of Africa, moving from place to place every day to kill all insects, animals and birds that come their way. These ants are very dangerous to humans: they climb on their prey from the ground or jump from trees, from where they stalk their prey. They bite with their powerful, sharp jaws and literally tear apart small specimens. Meeting with a colony of these insects, reaching 2.5 cm in length, does not bode well.

10. The Africanized Bee

The Africanized Bee

The Africanized Bee is one of the most dangerous insects in the world. An Africanized bee looks almost like an ordinary honeybee; only specialists can distinguish the two species in the laboratory. Their venom is not very strong, but the insects are dangerous for people, as they attack in large flocks.
