The Bull Ant is large with long, powerful jaws and a potent, venom-loaded sting. Many species of bull ants have bright red or orange colours on the head or/and abdomen.

The combination of appearance and ammunition emphasises this insect’s fearsome reputation. The Bull Ants build their nests underground, which can extend several metres in depth, and fiercely protect its boundaries. If an intruder of any size comes too close, the ants are known to follow and even chase the intruder away.

Their sting is extremely painful. The ant grips the intruder with its jaw, curling its abdomen to reveal a stinger before injecting their venom, often multiple times.

In some species these war-like insects have no colony workers. Instead, a raiding queen invades the nest of another species, kills the resident queen and takes over the colony. Invade and conquer obviously a motto with this species.

Along with the Honey Bee, the Bull Ant can kill because of the anaphylactic reaction some people can have as a result of the sting.

So when out and about: be alert and keep your distance when coming in close proximity to a Bull Ant nest.
