Killer ants are a species of highly predatory and aggressive ants that attack in large numbers if their mounds are disturbed or if they spot an immobilized animal, even deer. Apparently, more deaths are caused by these ants than by any other predatory animal. If their ant hills are disturbed, the first ant who attacks leaves a hormone in the air. Sensing this, other ants come and attack. So at one time, there is a possibility of more than 5000 ants attacking. This, of course, depends on the size of the colony.
Types of Killer Ants
Fire Ants
Fire ants are one of the deadliest ant species. They attack en masse, in large numbers all at once. They are found in many regions of the world and are highly aggressive. Their sting is very painful. A few hours later, the stung site develops white, pus-filled blisters.
They vary in size from 1/16 to 1/5 inches long. They are dark-red in color and have a brownish abdomen. Their mounds are roughly 15 inches high with a diameter of 15 inches, and are up to 5 feet deep. Fire ants are known to kill small animals and even calves. As mentioned above, if one ant bites, there is a possibility that the entire colony will attack. Humans can die due to anaphylaxis, and animals who can't get away fast enough are often consumed.
The Argentine Ant
These dark ants are native to Argentina but were introduced to different parts of the world by humans. They are known to invade other ant mounds and human settlements. They are of great importance to the medical world, as it is believed that they are capable of carrying pathogens into hospitals.
Argentine ants are about 0.12 inches long. They have one queen ant for every 10,000 workers. They multiply mainly by dividing their colonies and relocating. They are known to destroy the habitats of other animals and ants in the ecosystem. It is believed that they are responsible for the declining numbers of the horned lizard found in California. They also protect pests in farmlands in exchange for a substance known as honeydew, which means damage to crops also increases with their presence.
Bulldog Ants
Bulldog ants were once widespread across the globe, but today they are only found in Australia. These ants attack bees and local ant colonies. Their favorite food source is the carpenter ant. Unlike other ants, they are not very cooperative amongst themselves, the only thing they do as a group is tend to the larvae. They have very sharp vision and are known to be very aggressive towards intruders, including humans.

5 quick questions. How much do you know about the world's most dangerous ants?
Bullet Ants
Bullet ants have the deadliest and most painful sting in the world. They are huge in size, about 1 inch long. The intense pain from the sting lasts for about 24 hours. They get their name from the fact that being bitten by them is similar to getting shot by a gun.
Some young boys of South American tribes have to go through this ordeal for their initiation into manhood. The ants are woven into gloves made of leaves, which the boys wear. They have to endure the bites for up to 10 minutes. The arms of these boys quiver for almost a day and are nearly paralyzed during that time.

The Siafu Ants
Siafu ants are the killer ants of Africa and are amongst the deadliest species. They do sting, but what is worse than that is the hold of their jaw. It is said that once the ant bites, the only way to save yourself is to 'break' its body from the jaw and run. When food is in short supply, colonies of up to 50,000,000 ants migrate through the African plains, killing anything that is edible, including animals and humans who can't get away fast enough.
In fact, the Maasai tribesmen use these ants as emergency wound sealers. They make the ant bite on either side of the wound and then break its body. The jaw can hold the wound shut for days.
The social lives of ants are surprisingly complex, even a species this deadly runs on intricate chemical signals.
