The World’s Deadliest Insects

There are some pretty deadly insects roaming around the globe. Although they help to keep our ecosystem wonderfully balanced, they are definitely worth avoiding! We have listed our top five deadly insects, as there were simply too many to choose from and we didn’t want to leave you terrified with a terrifying list of deadly insects. So, below are our top five. Give it a read and let us know your thoughts.

Bullet Ant

The Bullet Ant is the largest of all ant families in the world. Living in the South American rainforest and growing to around one inch long, the bullet ant is named after its painful sting. Just one bite if thirty times more painful than that of a wasp or honey bee. The pain from their sting can last 12 -14 hours, which is why the bullet ant can often be referred to as the ‘24-hour ant’.

If the bullet ant comes across a predator it will release an unpleasant odour to drive it away. If that doesn’t work, bullet ants will attack predators in big groups with their powerful stings.

Fire Ants

There are 285 different species of fire ants in the world and they are not pleasant. If they are disturbed, they will sting the intruder repeatedly. Hence their name, the fire ant sting is very painful and can even last for a couple of weeks! Their venom has been known to cause several skin problems and it can result in allergic reactions.

Fire ants are noticeable by their reddish-brown colour. Fire ants live in mounds by their thousands. Some colonies have been known to contain over 200,000 ants. Fire ant colonies are typically comprised of female worker ants and one queen, who is responsible for laying the eggs. Workers create underground tunnels that can extend up to 25 feet away from the mound. It can take several months for a colony to grow a mound that is large enough to be visible.

Killer Bees

Killer bees, also known as Africanised honey bees, are one of the most aggressive and dominant insects in the world. When provoked, the bees become alert for the next 24 hours and will attack anything that comes within their range. Following their victim for more than 1 mile, killer bees will attack in groups by repetitively stinging. Killer bees mainly target the face and eyes of human for maximum impact.

Driver Ants

Driver ants have the largest colonies of any other insects in the world. Every colony of driver ants can have up to 22 million members. Their numbers are so great that even elephants would run away from a group attack. They are also sensible to run away as driver ants will try to finish off any animal that comes across their path. In a single raid, driver ants normally kill thousands of different animals by using their strong mandibles and making repetitive wounds. Driver ants also raid the nests of other insects for food and kill them.


Mosquitoes are the most dangerous insect species on Earth. More deaths are associated with mosquitoes than any other animal on the planet. They cause 1 million deaths every year by transmitting malaria into their victims. Mosquitoes carry malaria germs from one place to another and they transmit the germs into their victims by biting them. As well as spreading malaria, mosquitoes also spread dengue fever, yellow fever, encephalitis and west Nile virus.

Only female mosquitoes feed on human blood because they need protein for their eggs and must take a blood meal to reproduce. Since male mosquitoes don’t reproduce, they tend to feed from flowers instead. Basically, male mosquitoes are not as scary.
