Why Do Ants Fight?Colony Stasis

One of the things most people know about ants is that their colonies have one queen that lays eggs. It’s been long speculated that one of the reasons ants fight in their own colonies is to protect the status of their queen when another female starts to lay eggs. However, recent evidence suggests that one of the reasons ants fight is to keep their colony healthy.

When an ant colony grows too large, it can cause a scarcity of food, putting the health of the colony at risk. There is evidence that ants fight and kill other ants in order to maintain a sustainable colony size.


Ants are similar to humans in a variety of ways, including their reasons for conflict. When two ant colonies go to war, it is for reasons that should be familiar to humans: Resources.

If two large ant colonies are located in the same area, it means they will be competing for resources — especially food. As you might expect, this easily leads to conflict between colonies, and usually all-out warfare. Ant colonies require a large amount of food to survive, and will fight in order to acquire this food.


Another way ants are similar to humans is that they are extremely territorial, and this is another reason that ants fight. If a colony believes it is being invaded by another group of ants, they will fight to the death to protect their colony. Typically, ants fight by swarming, which is when multiple ants surround and attack a single ant.

While ants will most commonly fight to protect their colony from other species of ants, they will also work together to defend their home against other invasive species. So, much like humans, ants will fight as hard as possible to protect their home.
