Ants living on top of trees get enough rain or moisture from the atmosphere to stay alive without water. But the ants on the ground will not have this luxury. They will have to consume water, or they might dry up.

´╗┐Ants can generally live up to two weeks without water. Any more than that, and they will be dehydrated and dry up.

Ants generally look to find water wherever it’s available. They can drink water from the ground or the stagnant water on the leaves. Any source of water is okay for the ants and beneficial for their nests.

Can Ant Colonies Survive Without Food or Water?

Ant colonies generally do not survive without sufficient food and water for a long time. Ants might even get a new queen to sit at the helm by removing the previous queen from a majority group.

They will start with larvae with just what food they are left with for survival. No matter how many ants are part of a colony, they will not survive without any incoming food for more than two weeks.

The ants will scavenge whatever food they can find to try to avert this catastrophe. They’ll eat all the food in their colony. Within two weeks, if there is no incoming food, they will die.

How Long Do Ants Live? (Caste System and Lifespan of an Ant)

Ants live in a society that follows a strict caste system, and the life expectancy of an ant depends on their caste. Ant society is classified into males, females, and the queen.

Each of these castes has its own adjusted life span. The male ants have only one job: to mate with the queen.

 How Long Do Ants Live Without Food or Water?,

Due to their limited purpose, they generally live one to two weeks at most. To avoid unnecessary reproduction, the female ants are sterile. They are the worker ants whose job is to collect food, protect the colony, and take care of the queen.

The lifespan of worker ants greatly depends on available food sources and conditions. It generally ranges from a couple of weeks to a couple of months. There have also been cases where the worker ants lived for several years.

How Long Does a Queen Ant Live? (Lifespan of a Queen Ant)

The queen ant has a long lifespan. A queen ant can live up to a decade and keep reproducing and laying eggs. Some queens can live for fifteen years, while some have even touched the age of twenty-eight.

The worker ants tend to live longer as compared to other castes. They have a life span of about two weeks to two months. The males generally live for about a week or two.

The queen, on the other hand, breaks all boundaries and limitations. Living for more than ten years is a lot compared to normal ant lifespans.

What Do Ants Eat?

Ants have diverse preferences. They eat various things like animal matter, carcasses, human garbage, and plant matter such as aphids and other insects. They also feed on sugary things that are spilled or leftover by humans, like drinks and other food.

The worker ants try to gather as much food as possible all the time. The queen demands a lot of food. It also has to be enough to feed the whole colony.

Thus, the worker ants are the hardest working ants in the colony as they relentlessly work to find food. They even protect the entire colony.

What Do Ants Use Food or Water For?

Ants have two main uses for food: eating and feeding their larvae. Insects relentlessly gather food for the survival f their colony.

Ants that live on high trees or rocks are more energetic than those living on the ground. Thus, they do not need as much food or water as they have a continuous moisture supply around them.

Foods provide essential vitamins and proteins. These are necessary for the ants to become healthy for significant activities like reproduction.

Ants need food to survive, and the most common practice for ants is to eat foods rich in proteins and vitamins. Ants will store unused extra food in chambers known as granaries.

Feeding the larvae is another important task for adult ants. The worker ants find food and paste the food into their mouths. This way, it becomes easy for the larvae to consume the food.

The larvae are allotted aphids and sugar to give them enough energy for growth. Without this nourishment, the larvae will die as they cannot live on their own before adulthood, that is, before hundred days.

When the ant colony runs out of food, the queen is forced to live off her fat reserves. Eventually, she will lay unfertilized eggs that will turn into males.


Hence, in conclusion, the question of how long can ants go without food, ants can go without food for a long time. They have been known to survive for up to two years without food. However, they will eventually die if they do not have access to food.

They cannot live for long abstaining from food and water consumption. As mentioned earlier, ants need food for eating, and the young larvae can survive for four to ten days without it. They need water for hydration and energy restoration like any other organism and can live for about a week or two without it.
